Clarity around lifting roles is one of the biggest determinants of whether a pick happens safely or turns into a tangle of assumptions. On UK sites the Appointed Person (AP) and the Lift Supervisor are complementary, not interchangeable. One engineers and coordinates the lift; the other makes it happen on the day. When those lines blur, plans get bent by programme pressure, change control falls apart and people drift into risk without realising.
TL;DR
/>
– The Appointed Person plans and coordinates the lift end-to-end, including crane choice, ground checks, load path and interfaces.
– The Lift Supervisor runs the lift on the day, briefs the team, verifies the setup matches the plan and stops if conditions change.
– The AP appoints competent people and signs off the plan; the Lift Supervisor manages slingers/signallers, comms and exclusion zones.
– Changes mid-lift go back through the AP unless it’s an immediate stop for safety; shortcuts are where incidents start.
The roles in plain English: planning versus supervision
/> The Appointed Person owns the lift from a planning standpoint. They decide how the lift will be done and put it in writing, with drawings and a method that fit the site. That includes selecting the crane type and configuration, checking ground bearing and mats, confirming access and traffic management, and specifying lifting accessories, slings and rigging arrangements. The AP coordinates with site management, temporary works and utilities to make sure the lift doesn’t clash with excavations, scaffolds, overhead lines or other operations. They also nominate the Lift Supervisor and slingers/signallers, and make sure competence, appointments and briefings are handled.
The Lift Supervisor is the site lead once the crane shows up. They verify the crane and rig match the plan, control the exclusion zone, check weather and comms, and deliver the brief so every person in the team knows the signals, load path and abort points. If anything is off — ground soft, loads different from what’s stated, radios flaky, traffic encroaching — the Lift Supervisor pauses the work and escalates to the AP to resolve, rather than “making it work” on the fly. They keep the lift aligned to the plan, maintain contact with the crane operator and slingers/signallers, and manage the pace so programme pressure doesn’t erode control.
How it unfolds on a live UK job
/> Civils job in winter, mobile crane booked to install precast manhole rings beside a live access road. The AP’s plan shows outrigger positions, mats, a segregated route for site traffic and a single pick point to avoid slewing over an excavation. Utilities have been scanned and marked, and the Temporary Works Coordinator has confirmed the ground bearing assessment. On the day, the Lift Supervisor arrives early, checks the mats are the right grade and in the right place, and finds that overnight rain has softened a verge near an outrigger location. They halt the setup, ring the AP and agree a minor reposition within the planned envelope that still keeps clear of the excavation and services. The briefing is re-run with the new outrigger marks sprayed, traffic marshals hold deliveries for 30 minutes, and the lift proceeds under radios with hand signals as backup. A gusty shower later prompts a stop for ten minutes until conditions settle.
Interfaces that make or break the lift
/> Lifts rarely happen in isolation. The plan needs to lock in who controls the work area and how other trades and deliveries are kept out. Load paths, slewing limits and landing areas must match the actual site rather than an idealised drawing. Ground conditions, temporary works, buried services and proximity to edges or openings must be accounted for. Radios and hand signals should be agreed and tested, with a simple, understood abort call. Weather limits and “no-go” triggers belong in the briefing, not buried in paperwork. And if the lift involves public interfaces or highways, traffic management needs to be booked and set before the crane outriggers go down.
# Pre-lift interface checklist
/>
– Appointment letters for AP, Lift Supervisor and slingers/signallers are in place and checked for competence.
– Walk the load path and mark the exclusion zone; put barriers and signage in before the crane rigs.
– Confirm ground bearing assessment, outrigger mat size and placement; get temporary works sign-off where needed.
– Verify lifting accessories match the plan and inspections are in date; reject anything ambiguous.
– Test radio channels and confirm hand signals as fallback; make sure everyone can hear instructions.
– Deliver a clear brief including load weights, landing points, slew limits, weather thresholds and abort wording; record attendees.
– Confirm traffic management, permits and delivery timings; hold other work that would encroach on the lift area.
Pitfalls and fixes on planning versus supervision
/> One recurring pitfall is a “copy and paste” plan that doesn’t reflect current site reality — a scaffold has moved, a trench is now open, or a delivery route has been re-routed. The fix is simple but disciplined: APs do a site walk with the Lift Supervisor before finalising and brief with the latest drawings on hand. Another issue is competence drift: someone once deemed competent moves role or hasn’t lifted for months. Keep appointments live by refreshing evidence, observing practice and stepping people back for refresher toolbox talks when signals, rigging or documentation standards slip.
On the supervision side, the pressure to “just get it in” encourages improvisation when ground is soft, loads are heavier than thought, or the wind picks up. The correct response is pause and escalate: the Lift Supervisor owns the stop, and the AP owns the re-plan. Plan for change by writing clear “if-this-then-stop” criteria into the brief and making it culturally acceptable to use them without debate.
Common mistakes that cause confusion
/>
Treating the AP and Lift Supervisor as the same person by default
Combining roles can work on small, simple lifts, but it often overloads one person and blurs checks and balances. If combined, protect time for planning and a second set of eyes on the day.
# Omitting ground checks and temporary works input
/> Outrigger loads and ground bearing capacity are frequently guessed. This is where cranes sink, slabs crack and near-misses happen; get the right mats and sign-off.
# Assuming an experienced operator will “sort it”
/> Operators are vital but they follow the plan and the Supervisor’s instructions. Handing them the planning gap puts them in a no-win position.
# Making mid-lift changes without involving the AP
/> Shuffling mat positions, moving landing points or lifting different loads seems minor until it isn’t. Stop, call the AP and document the change — that’s control, not bureaucracy.
Keeping momentum without shortcuts
/> Clear separation between planning and supervision doesn’t slow a job; it stops rework and incident fallout. Give the AP space to plan with the site picture, and empower the Lift Supervisor to hold the line on the day. Where changes are likely — weather windows, shared access, late deliveries — plan the hold points in, not as an afterthought.
# Next week’s lift improvements to land
/> Walk the next three lifts together — AP and Lift Supervisor — and mark any site changes on the plan before issue. Swap two-way radios for headsets where hand signals are obscured, and rehearse the abort call. Move the briefing closer to the crane so everyone can see the setup being described. Put a simple “red flag” card in the Supervisor’s pocket listing stop triggers. Photograph the setup and keep it with the completed lift record to close the loop for learning.
The distinction is straightforward: the AP engineers the lift; the Lift Supervisor enforces the plan. Keep those gears meshed and you avoid the grey zones where time pressure writes the method — and that’s where enforcement attention is increasingly focused.
FAQ
# Does the Appointed Person have to be on site during every lift?
/> Not always, but they must ensure the plan is suitable and the Lift Supervisor is competent and fully briefed. For complex or high-risk lifts, it’s good practice for the AP to attend or be readily available to deal with change.
# Who decides when to stop a lift if conditions change?
/> The Lift Supervisor has the authority to stop immediately if anything looks unsafe or deviates from the plan. Any subsequent change to the method or setup should be agreed with the AP before restarting.
# Can the crane operator act as Lift Supervisor on a small job?
/> It can be done on simple lifts if competence and capacity align, but it concentrates multiple roles on one person. Make sure the supervision function isn’t diluted and that communication and exclusion zones are still managed.
# What paperwork should be in place before the crane rigs?
/> A current lift plan with drawings, appointment letters, accessory inspection records and a signed briefing record should be available. Where required by site rules, include permits and any temporary works or ground bearing confirmations.
# How do we handle conflicting work near the lift area?
/> The AP should coordinate sequencing in the plan, and the Lift Supervisor should enforce the exclusion zone on the day. If other trades or deliveries encroach, pause, re-establish controls or re-sequence; do not “thread the needle” through active workfaces.
