General
 Hoisting is a high-risk activity and requires high skills.
 Before hoisting, check the environment carefully to ensure that the anchor points are
stable.
 Before hoisting, check the tools carefully to ensure that they are intact.
 Read the technical notice before viewing the following techniques.
 It is important to fully understand the information provided in the technical notice
before using this complementary information
 Mastering these techniques requires training and practice.
 Consult a professional before attempting to perform these techniques on your own.

SAFE Hoisting
Introduction

Each added pulley will
reduce 50% of load

Hoisting Material
Guide Rope
Traction Rope
Limit ≥ 25Kg
Pain points:
• At least 03 person
• 100Kg load = 100Kg effort
• Release rope = material drop
• Pulley anchor by hook (slide)

Hoisting Material
Guide Rope
Traction Rope
Limit ≥ 25Kg
Pain points:
• At least 03 person
• 100Kg load = 100Kg power
• Release rope = NOT drop material
• Pulley anchor by EYE (NOT HOOK)
Rope move in one direction only

To use of blocking knot require
practice training in order to get
ability.
The knot must be strict adjusted
according with requirements,
otherwise it will not work properly!

Hoisting Solution
Safe + Mechanical Advantage

Traditional Solution – 04 PERSON
Guide to prevent the antenna from
shaking and collide with the tower.
Antenna >25kg
Worker on tower watch and help hoisting,
Worker on ground hoisting,
Worker on guide rope support to reduce the swing
Guide Rope
Traction Rope
Limit ≥ 25Kg

Traction Rope

Self Guided Hoisting – 03 PERSON
Antenna
>25kg
Using cam pulley or locking knot as fall
arrestor, preventing material down when the
pull staff want to rest or lost the rope control.

Using cam pulley or locking knot as
fall arrestor, preventing material
down when the pull staff want to
rest or lost the rope control.
The traction rope guide and avoid that
antenna shake and collide with the
tower
Antenna
>25 kg

Fall arrestor VS fixed pulley with the progress capture
locked up
15
Fall arrestor
 At the equipment side
 Low efficiency,85%
 Cannot adjust
 On the top
 High efficiency , 95%
 Easy to lock or unlock
Fixed pulley with the progress capture locked up
Both fall arrestor and fixed pulley with the progress capture locked up could reduce the fall risk, help
workers have rest when hoisting
