2.1 Tools and Equipments
A Pulley of the correct Safe Working Load (SWL), for the load to be lifted must be used and must be
of high quality; with SWL clearly marked on the pulley. (Snatch or closed Pulley block is acceptable).
Typically this will be rated at least 3x the load that will be lifted. Huawei Subcontractor must use
2000kg SWL as a minimum. The pulley shall be in good serviceable condition and fit for purpose
and visually checked before each use. Any obvious signs of damage or over use and the Pulley must
be replaced for the same type.
Only Manual Hand Winches are to be used and this must have a load capacity suitable for the load
to be lifted and must be in a serviceable condition. Typically this will be rated at 3x the load to be
lifted. Hand winches factory certified and complete with the correct leg mounting brackets (2000Kg
SWL).
For extra safety a 2000Kg nylon sling will be wrapped around the winch Leg brackets and fixed with
an appropriate Bow or D shackle (SWL 2000Kg - not tied). In addition to the above, the Operator
must be fully trained and experienced in the use of the hand winch and the rigging work must be
properly supervised by qualified And certified engineers at all times
The number of turns of wire rope on the drum should be a minimum of 4 turns and the Operator
Must be wearing good quality leather gloves and shall keep his hands away from the Winch
When in operation at all times.

The teams on site must attach Barricade Tape and place safety signs on and around the working
areas, as well as clearly identify the rigging drop zones (half the working height) these areas must
be taped and cordoned off, site access gates must be locked and secured when the rigging work is
ongoing & all engineers are made fully aware of the site safety emergency gathering area in case of
any sudden incidents/accidents.
Safety signs must include the below information:
1. Hard hat Area. (Boots, Hat, Harness, Gloves & Glasses).
2. Personal protective equipment area.
3. Emergency Call information / telephone numbers and emergency contact numbers:
4. No Access to the Public / Local community.
5. Danger men working overhead / at Heights.
Site barricading:
Red and white or yellow and Black cordon tapes can be used for marking out safety areas..

2.3 Site Worker Preparation
Work Safety Analysis:
A complete Safety Analysis is to be carried out and analyze the risks of the specific site and the
activities of the rigging & planned installation work.
The process is to simply indentify the possible site dangers / risks and the probability or likely hood
of any occurrence due to the identified site risks, the TL must then measure the risks severities and
clearly instruct the team members on how to control all site risks and place tape or cordons around
any of the identified risk areas and brief the team in them all.
Tools box talk:
Each site Team Leader must hold a site installation tools box talk with all members on site, the TL
must fully explain all of the work activities and all engineers informed of their individual roles &
responsibilities be clearly defined.
All member of the team are to be briefed in the first aid and site accident procedures and be made
fully aware of the contact call numbers in case of any incidents, all near misses are to be recorded
and reported as they occur.
Tools box talk contents:
Visual checking analysis of tower or structure condition, site condition safe from danger animals
such as snakes, bees, monkeys etc, First Aid kit check.
Documentation check and brief on the installation requirements is needed. Safety brief, tools
checking, Installation tools checks, Job Arrangements, Rigging tools checking such as Pulley, Sling,
Webbing, Full body harness, all TB talk results logged and recorded.
Engineer Certification check:
Huawei identity Pass & ID as well as WAH Certificatation must be checked: All members of the
team should carry their WAH certification (Copy) with them on all site installations, they must be
fully trained at WAH and HSE by Huawei expert, and all Riggers must hold WAH Certificate from
Menakertrans / Professional Consultant, any persons found to be on site working without the
correct certification will be immediately removed from site and their photo taken, details logged
and reported to the HSE HW manager.

4 Drop Zones, Safe working areas and emergency rendezvous areas:
4.1 Drop Zones:
The drop zone is 50% of the actual Working height, or the actual location of the installation.
Example: If the team is working at 30m height the drop zone then becomes 15m from tower base
to surrounding area.
4.2 Safe working areas:
If there are residents living or in the vicinity of the Working Drop Zone Area, inform them about the
dangers and risks involved, ensure safety arrangements are in place & tape off the the drop zone
working area, placing signs around the boundary..
4.3 Emergency Rendezvous Point:
The Team leader must chose a safe area of the site or immediate surrounding area as an
emergency gathering location for the whole team to use in case of any accidents occurring.
In case of any accident occurring or very bad weather, i.e. lightening, hard rain, all work must stop
immediately, climbers must return to ground level and wait in the safe area until the immediate
risks have been addressed or removed or the adverse weather has passed and cleared.
4.4 Site Visitors/ Inspectors:
In the case of any persons visiting the site or trying to gain access to the site whilst the work is
being undertaken, the team leader must ask the persons to wait outside the working area outside
of the cordoned off drop zone. The tea, leader must challenge the visitor for their I.D then allow
to enter site, only fully trained persons are to enter sites, they must show their professional
credentials & certification, TL must report all visitors to the HW RPM

5 Basic Lifting Processes
Before any Lifting starts, the Team Leader must make sure that the Job Safety Analysis, safety sign
and barricade tape, emergency call and Tool box safety talk safety is completed.
Print out the plan or approved method of procedure (MOP, TSSR etc) and follow the plans and
make sure all team members who are involved in the lifting activity fully understand their roles, the
plan and the approved procedures. There must be 1 Team Leader/Supervisor assigned to the site
installation, he/she is fully responsible for making sure all activities run smoothly and as planned.
Test lifts, Lift slowly under control, communicate the lift progress and stop slowly when at the
correct height. Fully check & Ensure all wire rope and blocks are running freely and not snagging or
rubbing in any way possible, if there is any rubbing or snagging of the lifting line found the TL must
re route the lines and ensure that the lines are free from hindrance free pulley blocks and lines at
all times when under stress...
Stop the activity slowly & under control for any issues that arise or that cause concern, check them
thoroughly and then proceed under control with one engineer climbing with the lift in his vision
and manage the lift until it is in the correct landing position on the structure..
6 Lifting Techniques (in Brief).
Ensure the pulley blocks are secured firmly and correctly in the tower leg, not bracings.
The Wire rope is free from any friction and rubbing and wrapped on the winch correctly (4
turns).
Let Taglines run freely under control, avoid any damage to equipment on the tower
No member below the lift Antenna /communicate well with winch controller.
Lift slowly and stop slowly under control at all times, follow the lift & climb as it rises.
Use double pulley to lift the Antenna / safety and back up.
Install blocks/pulley horizontally across the tower face.
Mark the drop zone at location and barricade off.
Stop at the correct height and lock of all winches and tag lines. (Secure the lift/make safe.).
Square Rigging Pulleys and Line
Note: Installation Pulley to tower leg, the structure must be free from corrosion, strong and firm
and then the pulley blocks attached with Nylon slings and shackles.

Pulley Block Placement:
All Pulley Blocks must be attach to the structures correctly by using webbing nylon slings and
shackle SWL 2000Kg. Pulley Blocks must be attached on the Leg & placed above a horizontal
bracing to prevent any slippage or displacement/movement of the pulley under stress.
6 Lifting Test & rigging checks.
6.1 SITE Process and Pre-Lifting checks.
1. Prepare all Lifting equipment and carry out the
Tool box talk, inform the team again for the
Plan of installation ensure all understand their
part clearly.
Team Tool Box talk briefing.
2. Attach the hand winch to the tower leg
Using the manufacturers winch mounting
bracket and a webbing sling for extra safety.
All Leg brackets must be factory, welded and
Installed correctly prior any lift testing taking
Place.

3. Attach two pulley blocks in parallel at the
Relevant working height by using the above
Attachment Techniques double pulley blocks
Are used and must be serviceable and fit for
Purpose, installed horizontally and handled &
managed with respect. Pulley blocks must sit
flush and be free of snags and any potential
Interference, all engineers MUST NOT rest their
hands arms or and tools on the wire ropes as lifting
is taking place.
The rigging engineers must keep a Safe working
distance of 1.5m when pulley blocks are in Service
and lifts are in operation and being made.
4. The antenna assembly is to be checked
thoroughly and all cables are secure and
attached correctly, then Lift the antenna slowly
until max 3m where the assembly is vertical
then stop the lift and carry out a visual check of
the wire rope runs and communicate to the
tower riggers & confirm with them that the
pulleys are running freely.
5. The winch operator must use radio for all
communication the tower riggers, the operators
must be experienced and skilled in the winch
operation and wear the correct PPE at all times.
gloves are to be worn at all times.
The excess wire rope must be managed
correctly and stored on a wire rope drum for
management and protection from any potential
damage.

QC&EHS Dept Huawei Confidential Page16/28
6. Once the above checks have been completed the
lift can continue, one rigger must climb with the
assembly and ensure that he is in communication
with the winch operator at all times, under no
circumstances whatsoever are any persons to stand
under the load when it is being raised.
7. All antenna assemblies must be attached to the
Tower legs correctly and the brackets and bolts
tightened to the correct torque settings of 30Kn.
8. Install the brackets and check that all flat, spring
washers, bolts and both locking nuts are tightened
using ratchet spanners/sockets NOT open ended
spanners as this can round of the nut. The Bolts
must protrude equally and not be twisted or
Mis-aligned in any way.
9. Make sure that the Antenna is aligned to 0 degrees
and according Azimuth plan found in the approved
site installation designs.

10. On completion of all antenna lifting Lifting and the
Antenna installation is finished, the Team leader
Must carry out a full and detailed do self inspection.
To fully check all aspects of the site installation. All
Aspects of the installation are the be in line with
the approved site designs and immediate
rectification made to any none conformances
found.
11. Site De-Rigging must be carried out in a controlled
and disciplined way, under NO circumstances are
any ropes, Pulleys, shackles etc, to be dropped or
thrown to the ground, all equipment and tools are
to be lowered to the ground in a controlled and
safe manner, all tools and equipment must be packed
and stored away correctly and Site clearing must
be made and the site left clean, tidy and secure.
No burning of any waste is to take place on any site
installation.
12. Tag Line Techniques:
Tag Lines or Holding out ropes are to be securely fastened to the antenna assembly and the far end
attached to a stable and load bearing structure (fence post, tree or equivalent), a 2000kg sling
wrapped around and Choked through itself, two 2000kg Bow shackles are then attached to the
sling loop and the Tag line fed through the shackle over itself. When lifting is in progress the
engineer simply feeds the Tag line through he shackle, the line is to be controlled carefully and
never held tight.
