ELGIN PELICAN® SERIES NP SWEEPER

The Pelican NP Sweeper efficiently cleans large, paved areas, such as streets and parking lots. It can be equipped with a broom on each side to increase total sweeping path. Side brooms also help to bring debris out of the gutter and onto the conveyor.

DESCRIPTION

DESC

RIPTIO

N

D-2

WHY SWEEP?Street sweeping is an essential part of sanitation. In health, ecology and aesthetics, the community benefits from clean streets. Clean streets reduce dust and dust-borne contaminants, bacteria from decomposition of organic matter, pollutants entering stormwater systems and accidents due to debris in the roadway. Community pride is enhanced by a clean environment. People are less likely to litter in a clean area. Tourists have a positive first impression of the community, which may encourage them to stay longer and return more often.

MECHANICAL/BROOM SWEEPERSMechanical, or broom, sweepers remove debris by sweeping it onto a conveyor. The conveyor carries the debris to a hopper. The No-Jam™ hopper conveyor of Elgin Pelican was originally patented. This revolutionary design sweeps debris up onto the conveyor, eliminating the problems of jamming.

PELICANThe Pelican is the world’s most popular sweeper. This three-wheel design is flexible enough to get into tight corners and around parked cars, yet capable of picking up large objects, such as branches, hub caps and bottles. When the hopper is full, the Pelican hopper dumps straight ahead into a dump truck or onto the ground. This straight ahead approach uses only one lane, to avoid blocking traffic.

PRINCIPLES OF OPERATION

D-3

DES

CR

IPTI

ON

WATER SPRAYA water spray system controls dust during sweeping. Nozzles spray water at the front edge of each side broom to moisten the dust being swept by the brooms. The amount of water sprayed is adjustable through use of a knob inside the cab.

A 220-gallon (830 L) tank supplies water to the spray system.

BROOMSHydraulically-driven brooms sweep the debris on the street onto the conveyor. The main broom is located behind the lower edge of the conveyor and directs the debris toward the conveyor. Side brooms are available on both the right and left sides. For sweeping these are lowered and rotated to move gutter debris to the conveyor.

The pattern that the brooms produce when the sweeper is stationary is a tool to evaluate the most efficient positioning of the brooms. The brooms can be adjusted to produce the best pattern and result.

CONVEYORThe heavy-duty, multi-ply reinforced No Jam™ debris conveyor (Figure D-1) transports debris deposited on it by the main broom to the hopper. Speed is in-cab controlled for variable forward and reverse.

Pavement contact is maintained by rubber dirt shoes on the sides and rubber deflectors under the chassis.

HOPPERDebris is collected in the 3.5 yd3 (2.7 m3) volumetric capacity hopper. The forward dumping hopper allows dumping to occur using only one lane of traffic. The dumping height is variable up to 9 ft 6 in. (2895 mm).

After dumping the hopper should be washed down for maximum efficiency and long life.

CABVisibility is a full 360° in the cab of the Pelican NP (Figure D-2). The door windows, full-width windshield, and rear windows allow the operator to see everything that is happening while sweeping.

CONTROLSAll sweeping functions, including brooms and hopper, are powered through in-cab controls (Figure D-3), located comfortably within reach.

For a complete description of all controls, see the Operations Section.

DRIVE WHEELSThe Pelican NP features a unique wheel motor design (Figure D-4) to provide power to handle all road conditions including steep grades. Sensors adjust the power required according to the load.

Ensure that the front of the machine is clear 9. before moving it forward. During operation of the sweeper, monitor the front round mirrors for people outside of your direct field of view.

! CAUTIONDo not lean out the opened window while sweeping. Doing so may result in injury by low-hanging branches, etc.

While sweeping, to keep the sweeper evenly 10. aligned with the curb, choose a focal point on the front of the sweeper, such as the edge of the mirror or a place on the hopper, and line it up with the edge of the curb ahead of the sweeper. This eliminates any tendency to oversteer the sweeper.Often check the level of water in the spray water 11. tank. Sweeping without water will result in poor dust suppression. The water gauge is visible through the right-hand, front, low cab window (Figure O-25).

Often check the amount of debris in the hopper, 12. and dump the hopper before it becomes overloaded. See Dumping The Hopper in this section for the procedure.

SWEEPING PATTERNSBroom sweeping patterns are a guideline of sweeping performance. Patterns should be checked daily.

A pattern may be wrong because of incorrect broom down pressure, incorrect broom angle, or excessive broom wear.

A pattern narrower than that in Figure O-29 indicates that there is too little down pressure, which will result in poor sweeping performance. A pattern wider than that in the diagram indicates excessive down pressure, which will cause the broom to wear too fast.

If a side broom is set too flat, debris will be scattered instead of being directed to the path of the conveyor. If a side broom is tilted at too large an angle, debris will trail or be scattered, and the broom will wear too fast. If the main broom is not kept parallel to the swept surface, the broom will wear into a coned (tapered) shape and will give poor sweeping performance.

If a broom’s bristles have worn to less than half of their original length, the broom will produce a small pattern and poor sweeping performance. To check the sweeping patterns:

Park the sweeper on a level, paved surface. 1. Where available, dark pavement is preferred.If the sprayers have been set to operate, set 2. the side broom water switch(es) (65 and/or 81, Figure O-30) to stop water spray.Set the MODE SELECT switch (77, Figure O-30) 3. to the SWEEP position.If the brooms have not been set for sweeping, 4. take the following steps.

Depress the MB/CONV HEIGHT switch a. (75) and the side broom height switch(es) (64 and 82) to lower the main broom and side broom(s). Each broom will lower to sweeping position, which depends on the down pressure setting (Figure O-30).As needed, use the side broom rotate b. switch(es) (67 and 79) and MAIN BROOM ROTATE switch (74) to start rotation of the brooms (Figure O-30).

Using the ENGINE THROTTLE SWITCH knob 5. (62, Figure O-30), set engine speed at 1500 to 2000 RPM.Sweep in one spot for 15 to 30 seconds.6. Stop broom rotation and raise the brooms by 7. setting the MODE SELECT switch (77, Figure O-30) to the TRANSPORT position.Drive forward far enough to reveal the patterns 8. left on the pavement by the brooms.Check that the side broom patterns are crescent-9. shaped and 3 to 4 inches wide at the widest part. The side broom patterns must overlap the path of the main broom (Figure O-29) to prevent trailing of dirt.Check that the main broom pattern is of an even 10. width along its whole length (does not taper). The pattern should be 4 to 6 inches (10 to 15 cm) wide. After sweeping, the broom bristle tips should have an even amount of dirt on all of them (Figure O-29).

If the patterns do not conform to those in Figure O-29, take one or more of the following steps as instructed in the Service Procedures section.

As needed, adjust down pressure of the brooms. •Adjust tilt of the side broom(s). •Adjust extension of the side broom(s). •Replace badly worn brooms with new ones. •

After taking any of the above steps, check the sweeping patterns again.

While checking the sweeping patterns, also check the dirt shoe (Figure O-31) on each side of the main broom. The dirt shoe housings should be flush with main broom, shoes should be level with the ground.

Procedures for adjusting the shoes are in the Service Procedures section.

FAULT DISPLAYSWhen the sweeper’s control system detects an electrical fault, it causes an audible alarm to beep and lights the fault warning indicator (33, Figure O-35) on the right-hand indicator panel (11, Figure O-35). These signals alert the operator to read fault codes being displayed in the code display window (13, Figure O-35) and to take appropriate action.

Codes will be repeated at intervals that depend on the urgency of action to correct the fault. For example, the code for a fault that could start a fire will be repeated more often than the code for a fault that only causes inconvenience.

Codes and their meanings are listed in the Electrical Section of the Services Manual.

HYDRAULIC SYSTEM

The hydraulic system of the Pelican NP is spline shaft driven. There are no belts to break or pulleys to adjust.

There are three basic hydraulic systems:

Hydrostatic drive system1. Hydraulic sweep system2. Hydraulic steering system.3.

All three systems share a common hydraulic oil tank (reservoir) and filter (Figure SP-3). The tank is located next to the engine on the right hand side of the sweeper. The tank is pressurized at 4 to 6 psi (30 to 40 kPa).

Check the oil level in the tank using the sight gauge on the side of the tank.

! CAUTIONHydraulic reservoir is pressurized. Opening fill cap before venting can cause personal injury. Open fill cap slowly to vent hydraulic reservoir.

NOTICEElgin Sweeper Company recommends Shell Tellus T 68 or equivalent hydraulic oil. Never mix different kinds of hydraulic oil. Use of any fluid not approved by Elgin Sweeper Company can void all hydraulic component warranties.

BROOM ADJUSTMENTBroom sweeping patterns are a guideline of sweeping performance. Patterns should be checked daily by the procedure in the Operation section of this manual.

If a pattern does not conform to the one shown in the Operation section, correct the pattern by using the following procedures, as needed. After all broom adjustments are made, the sweeping pattern should be checked again.

Clean sweeping and acceptable rates of broom wear are the final tests of broom adjustment.

SIDE BROOM ADJUSTMENTIf the sweeping patterns show that the side broom and main broom sweeping paths properly overlap, side broom tilt angles of 5 degrees outward and 5 degrees forward generally give good sweeping efficiency.

DIRT SHOE ADJUSTMENTDirt shoes ride perpendicular to the ground to act as a guide to keep debris between the main broom and the conveyor.

The main broom rotates between the two dirt shoes. Wings at the rear of each dirt shoe assure that the bristles are turned in and ride flush within the dirt shoe housings.

Both dirt shoes (Figure SP-17) should be correctly aligned, so the runners ride level with the surface of the road. If they are not correctly positioned, this should be corrected immediately.

To check for proper dirt shoe adjustment, use the following procedure.

Lower the main broom.1. Start main broom rotation.2. Drive the sweeper forward to allow brooms to 3. attain proper sweeping position.

Visually inspect the rotation of the main broom 4. between the dirt shoes.Raise the broom and drive forward to allow 5. components to attain transport position. In raised transport position the dirt shoes should be parallel to, but not touching the ground.

If the dirt shoes are not level in the raised 6. position, adjust them by moving the spring attached to the dirt shoe tow bar (Figure SP-17).

To raise the front of the dirt shoes, move the • spring attachment forward (only one hole at a time) to reduce tension in the spring.

To lower the front of the dirt shoes, move the • spring attachment rearward (only one hole at a time) to increase tension in the spring.

After leveling the dirt shoes in the raised position, watch how the shoes wear in continued use. If the shoes wear much faster at one end than at the other end, make another adjustment.

DIRT DEFLECTORSDirt deflectors are located in various places in the Pelican. They aid in keeping debris moving toward the hopper.

Dirt deflectors are installed between the conveyor and the chassis to prevent debris from spilling over the sides of the conveyor.

Two rubber deflectors span the width of the Pelican between the drive wheels. These can be removed, if necessary, during leaf removal season.

On Pelicans equipped with dual side brooms there is a center board (Figure SP-18) mounted beneath the middle of the unit. This board keeps the side brooms from throwing debris to the side beyond the path of the main broom.

ADJUSTING CONVEYOR BELTThe conveyor belt must be clean and the lower roll area flushed out prior to belt adjustment. Lower the main broom/conveyor and one side broom. Do not attempt to adjust the conveyor belt with the conveyor system in the raised position.

Proper conveyor belt adjustment involves setting belt tension and alignment. A properly tensioned belt will have good clearance between each belt cleat and the lower conveyor backing plate.

Too much slack will cause Flapping of the belt against the backing plate and result in damage to the belt.

The conveyor belt must be accurately aligned, or trained, to stay on the middle of the rollers. A misaligned belt can travel across the rollers and into the conveyor sides, where it will suffer tearing or other damage.

NOTICEIf the lower roll offset is properly adjusted before a new belt is installed, belt adjustment is easier. Proper offset can also help solve problems of alignment (TRAINING) with a belt that has been in use. See Lower Roll Offset Adjustment.

NOTICEAll belt tension adjustments should be made with no more than one-half turn of the adjusting nuts at any one time. The conveyor should then be run for several minutes (or the time specified in a procedure) with the engine operating at about 1200 RPM to check the results before making another half turn adjustment.

BELT TENSIONThe conveyor belt has correct tension when there is clearance between the tip of any cleat and conveyor backing plate. If too loose, the belt may slip on the upper roll and the cleats may show wear from dragging over the backing plate. DO NOT overtighten belt, as this will cause premature failure.

To adjust belt tension, use the following procedure.


Follow the procedure under Conveyor Access1. Loosen the jam nuts (Figure SP-20).2. As needed to achieve correct tension that is 3. uniform across the belt, turn both adjusting nuts. Turn the nuts clockwise to increase tension or counterclockwise to decrease tension. Turn each nut only one-half turn at a time.

! WARNINGContact with moving parts can cause severe injury. Do not attempt repairs or go underneath machine with engine running. Use extreme care when making checks or adjustments that require the engine to be running.

Operate the conveyor for at least 30 minutes to 4. check belt tension, alignment, and direction of travel, if any, over both the upper and lower rolls. If the belt FLAPS against the lower conveyor cover, increase overall belt tension by continuing adjustment steps on both sides of the upper conveyor roll.If alignment does not need adjusting, tighten the 5. jam nuts.

BELT ALIGNMENTProper belt alignment will require making small adjustments to the upper roll as outlined below. As a result, upper conveyor roll take-ups may not have equal final adjustments.

In some cases, adjusting the upper roll may not be sufficient to keep the belt centered on both rolls. It may be necessary to make similar adjustments to the lower roll.

NOTICEBelt tension, alignment, and centering adjustments for both rolls are interrelated. An increase in tension on one side of either roll should be accompanied by an equal decrease in tension on the opposite side to maintain proper overall tension. It is important to make small, equal adjustments and to check adjustment by operating the belt for at least 30 minutes before making another adjustment.

Reference to right or left hand side of the sweeper is relative to the operator’s position in the driver’s seat.

LOWER ROLL SCRAPER ADJUSTMENT

NOTICEThe condition of the lower belt scraper (rubber) that is part of the lower roll scraper assembly should be checked, and the belt scraper should be replaced, if necessary.

Lower roll scraper adjustment should be checked periodically and whenever the belt is removed. The square opening just above the lower roll bearing (Figure SP-23) provides access for adjustment. To adjust the scraper, take the following steps.

Loosen two nuts at each end of the scraper.1. Adjust the scraper to clear the roll by no more 2. than 1/16 inch (1.6 mm).Tighten the nuts.3.

NOTICEIf the belt splice is striking the scraper rubber during conveyor operation, the scraper needs more adjustment.

SPLICING CONVEYOR BELT! WARNING

Falling hopper can cause severe injury or death. Position both safety supports before going under raised hopper.

Before starting belt repair, follow the procedure under Conveyor Access.

A torn or damaged belt may be repaired in the field by cutting out the damaged part with a squared cut across the whole width of the belt and inserting a new section also squared off to match the length of the part removed (Figure SP-27). This requires two splices, one at each end of the new belt section added. Should damage occur near the original splice, the new section may be added at the end and only one splice need be added.

REVERSING CONVEYORThe conveyor assembly and belt adjustments are designed to train the belt in forward (sweeping) motion only. The reversing feature is only for brief use to help washing or to relieve jamming of the belt or driving mechanism. Normally the conveyor will not be run in reverse longer than 15 seconds. Longer periods of time may cause the belt to run either to the extreme right or left, causing damage to the belt.

NOTICEDo not operate conveyor in reverse for more than 15 seconds without allowing forward motion to center belt. Excessive reverse running can damage conveyor belt.

To reverse the conveyor, press the 3-position CONVEYOR ROTATE switch to OFF until the conveyor stops and then to reverse Just Long Enough to remove the jammed object.
