PREFACE

Jinlong Europe, a revolutionary evolution!

Reliability, quality, safety, and high technology are the success of Yongmaos topless

tower cranes all over the world.

In Europe all our cranes are CE approved. This is the result of a constanttechnological research.

Because of our relentless efforts to improve our products, technical updates are from

time to time necessary. Therefore, the technical data in this manual are subject to

change without warning.

Topless tower cranes, a revolutionary evolution.

1.3. CONCRETE FOUNDATION FOR FOUNDATION ANCHORS

1.3.1. PREPARATION

TOBEPREPAREDBYCLIENT:

The concrete foundation of the foundation anchors must be executed on basis of

the parameters in Table 1-3-1.

ATTENTION: The listed parameters are minimum values to be observed,

taking account of the stability requirements of the crane

Please contact us in case of deviating conditions.5

-27- RCVC.2.0.ENG

1.3.2. INSTALLATING THE CRANE FOUNDATION

The foundation must be defined taking account of:

- Type of crane

- The height of the crane

- The soil resistance

For this, we refer to table 1-3-2.

The crane reaction forces must at all times be less than the soil resistance.

ATTENTION: Incorrect installation of the foundation anchors may cause

crane instability, which, in turn, may result in an accident.

1.3.4. DIMENSIONAL FEATURES OF THE FOUNDATION ANCHORS

The foundation anchors must be placed symmetrically in relation to the

axes of the block and have to form a 2m square according to the dimensionof the mast they have to support.(fig. 3-3-1 en fig. 3-3-2)

ATTENTION: Please respect the 300mm distance between the mounting

plates and the fixing angles. See fig. 3-3-1.

1.4. COUNTER-JIB BALLAST

1.4.1. INTRODUCTION

The counter-jib ballast consists of various reinforced concrete blocks A, B orC. The counter-jib ballast is governed by the length of the jib. These blocks are

suspended one by one at the rear of the counter-jib.

Make sure that during erection the counter jib ballast will not be damaged.

The permissible weight tolerance is 500+ kg per block.

The manufacturing drawings are added in annex.

- Ballast 4000 kg fig. 5-1-1



NOTA: We recommend weighing the concrete blocks and marking their

weight with paint on a visible side of the concrete block.

1.5. REEVING (ZIE 2-5-8)

1.5.1. FROM DUAL REEVING TO SINGLE REEVING

- Bring the trolley against the jib foot and fasten it.- Lower the hoist hook down the ground (vertical position).- Remove the connecting pin (8) so that the single and dual hookblock

separate.

- Reinstall the connecting pin (8) on the single hookblock and secure itwith cotter pins.

CHAPTER 3. SLEWING MECHANISM

3.1. EXPLANATION OF THE SYMBOLS:

R T C

3.1.1. DESCRIPTION:

Select the slewing speed according to the required displacement. Increase or decrease

slewing speed gradually. Slow down gradually instead of stopping abruptly by means

of the slew brake.

The slewing brake may only be used to position the jib when hoisting at wind speeds

< 13 m/s.

To prevent damage to the hoist rope, avoid simultaneous slewing and hoisting (rope

twisting risk)

3.2. SLEWING MECHANISM

3.2.1. DESCRIPTION

The slewing mechanism RTC consists of:

1/ A squirrel cage motor turning at constant speed in the desired direction;2/ An electrodynamic coupling/brake producing the speed changes;

3/ A reduction in which the clutch engages directly on the slewing ring;4/ Safety brakes mounted on the electrodynamic coupling/brake;5/ Tacho-dynamo, for speed control;

6/ Slewing limiter;7/ The crane can be put in weathervaning both manually and electrically.


46/58


46- RCVC.2.0.ENG

3.2.2. OPERATION

1/ Make the motor run in the desired direction.2/ The brake releases.3/ The electrodynamic brake inductor is supplied with direct current.

4/ An amperage change in the inductor produces a speed change. In that way, thedesired speed can be obtained by means of the control box.

AT STANDSTILL:

- The power supply to the motor is switched off, power is supplied

to the inductor of the electrodynamic brake and the jib is brought

to a stop;

- The safety brake only locks when, in case of necessity, the operator

presses the thereto-provided button.

ATTENTION: Stopping the jib by counter-slewing is prohibited.

At the end of the workday, the jib must be placed in weathervaning.

Name

RP: Potentiometer

IC: Signal amplifier

Operation:

The control signal of the potentiometer RP (slewing mechanism RTC) is converted

through the amplifier IC to a single and three-phase AC-voltage that directly controls

the driving motor.

The slewing direction is controlled through a separate signal.

3.4. MALFUNCTIONS

1/ The slewing mechanism is provided with an electronic control device that:- Controls slewing acceleration and deceleration;- Prevents changing of the slewing direction by a control error;

2/ If a malfunction occurs, working with the crane must be stopped and its causemust be eliminated.

Table 5-3-1

Operation Normal Abnormal

Slewing movement from 0position on joystick. Slewing starts gradually up toits maximum speed. Slewing starts abruptly. Thetower deforms.

Slewing movement towards

0 position.

The slewing movement slows

down and stops after 7-10

seconds.

Slewing stops instantly. The

tower deforms.

Shunt bridging. Free slewing. Slewing stops suddenly.

NOTE: These malfunctions can have the following causes:

1/ Incorrect connection of the 380 VAC/48 VAC power supply; excessivevoltage fluctuations;

2/ Potentiometer and joystick are not compatible or are incorrectlyadjusted with reference to the resistance (O-R/2);

3/ Check if the inverter is intact and operates properly within theparameters;

4/ Check the connections of each part for damage and/or impropertightening;

5/Check if the control box still works within the given parameters.

4.2. TROLLEY BRAKE(ZIE FIG. 6-4-1)

4.2.1. DESCRIPTION:

The electromagnetic brake starts operating as soon as the power supply is

cut. Brake clearance in the active range is automatically adjusted.

Brakes:

When the current is cut, the electromagnetic atrractive force disappears.

The brake spring (8) pushes the pressure plate (6) back on the brake disc

(1-2). This closes the brake.

Opening the brake:

When the excitation coil (7) is excited, the pressure plate (6) is attracted

by which the brake compression spring (8) is pressed in. By this, the

brake discs (1 and 2) open up.

Brake clearance:

Normal brake clearance is 0.8 to 1.2 mm. Check brake surfaces for

soiling (oil- grease).

Brake moment adjustment:

The brake moment is set at the factory.

Opening the brake manually:

The brake can be released manually by loosing the brake yoke (9 en 10).

ATTENTION: It is prohibited to work with a manually opened

brake.

4.2.2. MAINTENANCE

1/ Every 200 hours or once a month:2/ Check brake clearance and brake moment, as well as the condition

of the brake discs. Normal brake clearance is normally 0.8 to 1.2mm.

3/ Attention: replace brake discs before they are completely worn.4/ Check if there is any foreign matter in the brake and if it is free

from oil and grease.

ATTENTION: The brake must immediately be inspected if:

-It does not work properly-It is overheating-Abnormal vibrations are noticed-Braking torque is insufficient
