Slings — Technical Guide
Chain Sling
Chain Sling
The toughest sling on site. Built for heavy, hot, rough, or abrasive loads. Alloy steel links with pear master link and clevis hooks.
Grade 8 / Grade 10LOLER 6-month exam
4:1
Safety Factor
–40° to 200°C
Temp Range
G8 / G10
Grade Stamp
Use When…
Heavy, rough, or abrasive loads
High-temperature environments
Steel, castings, or fabrications
Repetitive short-distance lifts
Do NOT Use When…
Polished or sensitive load surfaces
Temperature exceeds 200°C
Grade stamp missing or unreadable
Any link cracked, bent, or stretched
Step-by-Step — How to Use
1
Inspect every link — lay the chain flat. Check each link for cracks, nicks, gouges, bending, or twisting. Confirm grade stamp is present and readable.
2
Check the ID tag — every chain sling must show WLL, grade, length, and number of legs. No tag = remove from service immediately.
3
Select correct number of legs — 1-leg for vertical lifts, 2-leg or 4-leg for balanced loads. Confirm in the lift plan before rigging.
4
Attach to load lift points — hook each leg through designated attachment points in the approved hitch configuration. Never use a knot.
5
Master link to crane hook — seat fully in the bowl. Engage the safety latch. Confirm before signalling hoist.
6
Take up slack slowly — hoist until all legs are taut. Check balance. Lower and re-rig if the load tilts.
7
Store on a sling rack — never throw, drop, or drag chain slings. Impact causes invisible internal damage.
Discard Criteria
Any crack, nick, or gouge in any link — even hairline cracks cause sudden failure under load
Links bent, twisted, stretched, or opening — WLL has been exceeded
Wear exceeding 10% of original link diameter — measure with a calibrated gauge
Blue or yellow heat discolouration — chain has been overheated internally
Missing, illegible, or damaged identification tag
LOLER: Chain slings must be examined by a competent person every 6 months. Written examination report must be retained on file.
Wire Rope Sling
Wire Rope Sling
The industry all-rounder. Strong, flexible, and versatile — the most common sling on UK construction and industrial sites.

Safety Factor
Steel / Fibre
Core Type
To +100°C
Max Temp
Use When…
General construction and industrial lifting
Loads with rough or unfinished surfaces
Repetitive production lifting operations
Wet or oily working environments
Do NOT Use When…
Polished or easily marked surfaces
Sharp edges without corner protection
Broken wires visible anywhere on rope
Any kink, crush, or birdcage present
Step-by-Step — How to Use
1
Full-length inspection — uncoil and run your hand along the rope. Feel for broken wires, flat spots, kinks, and corrosion. Inspect ferrules at both eyes.
2
Check ferrules and eyes — swaged ferrule must be intact. Eye loops must not be stretched, deformed, or show wires pulled from the ferrule.
3
Identify all sharp edges on the load — fit corner/edge protectors before rigging anywhere the sling will contact a sharp edge.
4
Rig in the correct configuration — straight, basket, or choke per the lift plan. Do not change hitch on site without AP approval.
5
Seat eyes correctly on hook — eye must seat fully in the bowl of the hook, not balance on the tip. Engage safety latch.
6
Check sling angles before full hoist — both legs must be at least 30° from horizontal. Below 30° — stop and reposition.
7
Store hanging on a rack — never drag across the ground or expose to heat, grinding sparks, or corrosive environments.
Discard Criteria
6 or more broken wires in any one rope lay length — immediate discard
Any kink — a kinked rope cannot be straightened safely. Discard immediately
Birdcaging (strands splayed outward) — rope has been shock-loaded
Corrosion pitting or discolouration throughout the rope length
Crushed or flattened section, or ferrule cracked or pulled from eye

WLL values are for straight hitch. Basket hitch doubles WLL. Choke hitch reduces WLL by 20%.
Discard Criteria
Any hole, cut, or abrasion through the outer protective sleeve
Inner yarn visible — sling has lost its protection. Out of service immediately
Hard, lumpy, or uneven feel inside — possible internal yarn damage from overload
Chemical contamination — acids or alkalis destroy polyester yarn invisibly
Hitch Configurations
A hitch is the method of attaching a sling to a load. The same sling in different hitch configurations gives different WLL values. The lift plan specifies the required configuration — never change it on site without AP approval.
Straight Vertical Hitch
Straight / Vertical
WLL = 100%
Sling hangs vertically. Maximum rated WLL. Attachment must be directly above load CoG.
Basket Hitch
Basket Hitch
WLL × 2 (at 90°)
Sling loops under the load, both eyes to hook. Doubles WLL but load can rotate.
Choke Hitch
Choke Hitch
WLL × 0.8 (−20%)
Sling passes through itself and tightens. Ideal for cylindrical loads. Never on sharp edges.
Critical Rules — All Hitches
!
Sling angles matter — as the angle from horizontal decreases, leg load increases. Below 60°: caution. Below 30°: stop the lift — do not proceed.
!
Never change configuration on site — changing hitch type completely changes the WLL. AP approval required before any configuration change.
!
Test lift at 150mm — raise to 150mm and hold. Check balance, sling position, and load stability before continuing to height. Mandatory per BS 7121.
!
Choke hitch on edges — never apply a choke hitch over any sharp edge, protrusion, or weld bead. A sharp edge will cut the sling instantly under load.

Roles & Duties
Appointed Person
CPCS A61 · TAP001 or equivalent competence
Planning AuthorityLegal Duty Holder
1
Plan every lift — produce a written lift plan before any operation. Cover load weight, CoG, rigging method, crane radius, ground conditions, and exclusion zone.
2
Calculate loads and sling tensions — verify gross load including all rigging. Calculate leg tensions based on hitch configuration and sling angles at the correct safety factor.
3
Select and specify all lifting equipment — confirm all items hold valid LOLER examination certificates with adequate WLL for the planned lift.
4
Assess all site conditions — inspect ground bearing capacity, crane access, overhead obstructions, underground services, and weather constraints.
5
Classify the lift — determine whether routine, complex, critical, or tandem. Governs planning depth, personnel required, and supervision level.
6
Brief all personnel — confirm each person understands their role, hazards, communication method, abort signal, and emergency procedures.
7
Sign off and retain records — sign the lift plan as the competent AP. All documentation retained for inspection by the HSE or LOLER enforcing authority.
8
Remain independent — not subject to programme or financial pressure. Has absolute authority to suspend or cancel any lift considered unsafe.
Crane Supervisor
CPCS A60 — covers on-site Lift Supervision duties
On-site ControlComplex & Critical
1
Confirm crane setup — verify crane is positioned per the lift plan. Outriggers fully extended, pads on firm ground, crane level within manufacturer's tolerances.
2
Verify capacity at the required radius — check the load chart. Confirm gross load is within rated capacity. Never exceed 90% of chart capacity without specific AP approval.
3
Liaise directly with the AP — confirm the lift plan is fully understood. Report any deviation before operations begin.
4
Brief the lift team — deliver the pre-lift toolbox talk. Confirm each team member understands their role, communication method, and abort procedure.
5
Coordinate all disciplines — direct the crane operator, slingers, and banksman. Only one authorised signaller communicates with the operator at any time.
6
Inspect all lifting accessories before use — confirm slings, shackles, hooks, and rigging gear are in-date, correctly rated, and undamaged.
7
Monitor the lift throughout — watch for load swing, wind, bystander intrusion, or unexpected load behaviour. Ready to call an immediate stop.
8
Immediate authority to stop the lift — can suspend operations at any point for any safety reason without requiring prior AP approval.
RCI
Crane Operator
CPCS A02 (mobile) · A04 (tower) · NPORS N108
Machine ControlCertified Only
1
Complete pre-use inspection — carry out the manufacturer's daily checklist before operation. Record all findings. Report any defect before beginning lifting.
2
Operate strictly within the load chart — never exceed the crane's rated capacity at the working radius. If load weight is uncertain, do not lift without written confirmation from the AP.
3
Accept signals from one designated signaller only — if signals are unclear or stop unexpectedly — stop and hold the load until clarified.
4
Maintain smooth load control — slow, controlled movements. Never slew a load over personnel.
5
Monitor the RCI/ASLI at all times — do not silence, bypass, or override any load warning system without explicit instruction from the Crane Supervisor and AP.
6
Report unusual behaviour immediately — lower the load safely before any investigation of unusual noise or movement.
7
Never leave the cab with a load suspended — remain at the controls at all times while a load is attached and off the ground.
Slinger / Signaller
CPCS A40 · NPORS N009 · BS 7121 hand signals
Load AttachmentSignalling
1
Inspect all accessories before every use — visually check every sling, shackle, hook, and rigging component. Remove any defective item from service immediately.
2
Attach the load in the specified configuration — rig slings exactly as specified in the lift plan. Protect slings at all sharp edges with corner protectors.
3
Confirm load is fully secure before signalling — all shackle pins tightened and moused. Hook safety latches engaged. Load visually balanced.
4
Give clear BS 7121 standard signals only — use only the standard code or agreed radio method. Never improvise. Only one slinger gives signals at any time.
5
Manage taglines safely — never wrap taglines around hands, wrists, or any body part. Release before the load rises beyond safe reach.
6
Control the exclusion zone — challenge any person attempting to enter beneath or adjacent to the load path. Call an immediate stop if the zone is breached.
7
Control landing and detachment — confirm load fully set on adequate supports before releasing slings. Never stand beneath a suspended load.
8
Emergency stop authority — give the emergency stop signal immediately the instant any unsafe condition is observed. This authority overrides all other instructions.
Banksman
CPCS A31 (recommended) · Site induction minimum
Zone ControlTraffic Management
1
Establish and enforce the exclusion zone — set up physical barriers and signage before any crane movement begins. Control all access points.
2
Guide crane travel and positioning — direct the crane where the operator's vision is restricted by blind spots, tight access, or congestion.
3
Manage pedestrian and vehicle conflict — prevent vehicles and workers from entering the crane slew radius or load travel path.
4
Relay signals where required — where the slinger cannot be seen by the crane operator. Only one person gives instructions to the operator at any time.
5
Monitor overhead hazards — maintain awareness of power lines, structures, and other cranes in proximity. Alert the Crane Supervisor to any potential conflict.
6
Immediate stop if zone is breached — give the emergency stop signal immediately if any person enters the exclusion zone without authorisation.
How Many Slingers?

Slinger Lifted 20 Metres off the Ground
Human FactorsHigh Fatality Risk
What Happened
During a tower crane operation, a mortar tub was being lifted to upper floors. The slinger was still holding the tagline as the load rose. The tagline wrapped around his hand and he was lifted approximately 20 metres before operations were stopped.
What Went Wrong
Slinger remained holding the tagline during a live lift
Tagline wrapped and locked around the slinger's hand under tension
No monitoring of the slinger's position during vertical load travel
Key Lessons
Taglines are load-control tools — they must never control the person holding them
Never wrap taglines around hands, wrists, or any body part
Release taglines before the load rises beyond safe arm's-length reach

Tower Crane Lifting 7 Tonne Bags in One Lift
Supervision FailureOverloading Risk
What Happened
A tower crane lifted 7 tonne bags simultaneously at 25 metres using a single 4-leg chain sling. Bags were grouped without an engineered frame despite being rated for individual lifting only. Workers remained active directly below. The Crane Supervisor was advised to stop the lift but did not act.
What Went Wrong
Multiple tonne bags lifted together with no approved methodology or frame
Load CoG unstable — each bag able to move independently
Personnel remained in the exclusion zone beneath the suspended load
Key Lessons
Tonne bags are rated for individual lifting only — always check the label
Grouped loads require an engineered solution — certified spreader frame or lifting beam

Contract Lift Without Full Site Coordination
Supervision FailureSite Management
What Happened
A contract lift for HVAC units arrived to find the crane setup area occupied, access routes blocked, no exclusion barriers in place, and other trades unaware a lift was planned. Commercial pressure from the project manager pushed for the lift to proceed regardless.
What Went Wrong
Site conditions did not match the conditions described during planning
Exclusion zone not established before the crane arrived on site
Commercial pressure applied to proceed with clearly unsafe conditions
Key Lessons
A contract lift does not transfer site management responsibilities away from the client
Programme pressure is never a valid reason to lift in unsafe conditions

Lift Plan Not Fit for Purpose — Rejected at Validation
Planning FailureDocumentation
What Happened
A lift plan for a Minifor hoist contained only generic method statements. No rigging configuration, drawings, exclusion zone definition, or contingency procedures were included. The plan was initially accepted and used before being challenged.
What Went Wrong
Lift plan contained generic statements — not a specific method for this lift
No rigging configuration, hitch type, or sling specification included
Plan accepted by site management without proper critical review
Key Lessons
A lift plan must describe exactly how this specific lift will be executed
If the method cannot be read and visualised, it is not a lift plan

Tonne Bag Lifted by Knot — Not Certified Lifting Eyes
Equipment MisuseNo Supervision
What Happened
A slinger lifted a bulk tonne bag containing full gas bottles by tying a knot at the top rather than attaching through the certified lifting eyes. No supervision was present and the lift plan defined no lifting methodology.
What Went Wrong
Tonne bag not lifted from the manufacturer's certified lifting eyes
A tied knot was used as a lifting point — this has no rated or certified strength
Gas bottles lifted in a container not rated or approved for that purpose
Key Lessons
Tonne bags must only ever be lifted from the manufacturer's certified lifting eyes
A knot creates no safe or rated lifting point under any circumstances
