3.0 t and 5.0 t. Cite. The user information for this serial wins.

Retractable. Op Fam from Preston. Install is a licensed lift.

Crane-set. Anchors or MULTIPROP — host. User information for this serial.

Powered retractable. Install is a crane lift. Daily extend is host.

PURPOSE

Give the crew one method for installing, repositioning or striking a cantilever loading platform by crane. Rails, props, clamps and daily extend / retract stay with the host.

SCOPE

Operator, rigger and signalperson on a Doka, SuperDeck, CantiDeck, PERI RCS MP, DOC or other OEM loading platform. Not a how-to for propping, clamping, through-slab anchors, or rolling a SuperDeck in. Those belong to the manufacturer and the host. Landing materials onto a deck already in service is a separate lift — this SWP still names the WLL rule.

This document is the method — the steps. Hazards, consequence and residual risk for the same work are in the JHA library. A procedure is not a hazard analysis. A hazard analysis is not a procedure.

CITE — TYPICAL SYSTEMS. THIS SERIAL AND THE TYPE PLATE WIN.

SYSTEM	KIND	SERVICE / WLL	WHAT THE CRANE FLIES
Doka 3.0 t — 2.45 × 3.20 m	Fixed cantilever	3 000 kg	Empty. Dead weight ~1 580 kg + rigging. Not the service load.
Doka 5.0 t — 2.95 × 4.50 m	Fixed cantilever	5 000 kg	Empty. Dead weight ~2 670 kg + rigging.
Preston SuperDeck 2.2 / 2.6 / 3.2 / 4.2 m	Retractable drawer	5 000 kg typical	Empty. Host extends and retracts. Install is the crane lift.
Conquip CantiDeck Fixed Flush	Fixed cantilever	Type plate — often 5 000 kg	Empty. Props released before any hoist.
Conquip CantiDeck Super Roller	Retractable	Type plate	Empty. Stacked floors. Flush when retracted.
PERI RCS MP 375 / 550	Material platform	This serial	Empty. Host anchors or MULTIPROP.
DOC	Powered retractable	4 t	Empty. Host 110 V. Install / relocate by crane.

HITCH RULES THAT REPEAT. OEM USER INFORMATION STILL WINS.

RULE	WHO SAYS IT
Four designated lifting points. No improvised picks.	Doka. CantiDeck.
4-leg chain as the OEM. Doka: 3.20 m, β ≤ 30°.	Doka. CantiDeck.
Empty only. No material. No persons.	Doka. CantiDeck. SuperDeck install.
Do not lift until props / clamps are released.	CantiDeck. Doka reposition.
Tag lines. Doka: one. CantiDeck: front and rear, opposite corners.	Doka. CantiDeck.
One platform at a time.	Doka.
Reposition wind — Doka 72 km/h, or the lower of crane / this SJP.	Doka. Chart.
Disconnect only after the host says landed — jacks tight, rails pinned.	CantiDeck. Doka.
Daily SuperDeck / Super Roller / DOC extend and retract is host. The crane is not hooked.	Preston FAQ. CantiDeck. DOC.

PROCEDURE

01
GATE
OEM user information for this serial at the lift. Type plate. Engineered drawing if the site has one. Dead weight known (14.36) — empty, plus rigging. Not the service WLL. Pick points only as the OEM names. Wind — the lower of crane, manufacturer, this SJP. Doka cites 72 km/h while repositioning; a lower number still wins. GOSPEL-SJP-003 / FRM-053 filled. Critical lift plan. Radios tested. Pre-lift meeting immediately before this lift. Retractable or fixed — said. If any of that is missing, the hook does not take the deck.
02
HITCH
Four designated lifting points. Doka: welded points on the main beams. CantiDeck: the four points the user guide names. 4-leg chain as the OEM. Chain shorteners only if that guide uses them for hang. No two-point fly on a four-point deck. Inspect the hitch. Tag lines on — Doka one; CantiDeck front and rear, opposite corners.
03
EMPTY
No material. No persons. Doka: reposition empty only. SuperDeck install is empty. Loose gear off. One platform at a time. Fall protection at the slab edge (Part 11). Exclusion below.
04
RELEASE
Host releases props, clamps or through-slab anchors to the OEM. This procedure does not invent that sequence. CantiDeck: do not lift until the props are released. Take a little load, confirm free, then hoist. Do not strip with the crane.
05
FLY
Test lift. Hang as the OEM. Path. Tag lines. Wind. Hoist clear, then travel. A deck is a sail. Stop on any change. Do not fly over people (14.44).
06
LAND
Guide onto the slab. Host swings rails and props, pins them, clamps between slabs or sets through-slab anchors as the OEM. Doka: low storey — props laid flat only if that user information allows it. CantiDeck: screw jacks tight, thread as the guide. Do not disconnect until the platform supervisor says it is landed. Then release.
07
IN SERVICE
Landing materials onto the deck is a different lift. Chart capacity and remaining platform WLL both have to take the load. Unsupervised load on the deck is prohibited. The deck WLL is not a second chart for a pick the crane cannot hold.
08
RETRACTABLE
SuperDeck, CantiDeck Super Roller, DOC: daily extend and retract is host. Preston: no crane licence to roll it. The crane is not hooked while it moves as a drawer. Install, reposition and strike stay this SWP — empty, four points, props released.

RESPONSIBILITIES

This program

The published method for the work. Stop-work is named in it. It does not own the site.

Supervisor

Confirms the plan, the crew, the zone and the stop criteria. Owns whether the hook moves.

Crane operator

Runs only the machine they are competent on, to the chart, after inspection. Stops on an unclear signal or a broken plan.

Rigger

Selects, inspects and applies the hitch. Does not guess weight, centre of gravity or angle.

Signalperson

One set of hands on the crane. Holds the zone. STOP means stop.

Worker

Works to this program and to site rules — whichever is stricter. Uses the three rights. Reports damaged gear.

Platform supervisor (host)

Rails, props, clamps or through-slab anchors to the OEM and the engineered drawing. The crane crew does not invent a propping sequence. Says when the deck is landed and in service.

Prime contractor

Coordinates floors, exclusion, and who may land on the deck. Not a spectator.

REQUIRED COMPETENCY

BC Crane Safety certificate for this crane class
Critical-lift brief — everyone can repeat the abort
Knows the four designated lifting points on this serial, not last floor’s memory
Can say whether this deck is fixed or retractable, and who extends it

EQUIPMENT

This crane, this chart
4-leg chain and hardware as the OEM — Doka 4-part 3.20 m, β ≤ 30° if that is this serial
Tag lines
Radios on the named channel
GOSPEL-FRM-007, GOSPEL-FRM-009, GOSPEL-FRM-053

PPE

Hard hat
CSA-grade footwear
High-visibility clothing
Eye protection
Task-rated gloves
Hearing protection where required
Fall protection where the work exposes a fall

PROHIBITED PRACTICES

People or material on the deck while it flies
Flying the service WLL as the pick weight
Improvised pick points, missing legs, or a two-point fly on a four-point deck
Hoisting with props or clamps still in
Disconnect before the host says landed
Using the crane to retract or extend a SuperDeck
Last floor’s SJP for this serial

EMERGENCY RESPONSE

Deck hung up, dumped at the edge, dropped object, person in the zone, wind pickup, lost radio — stop. Land if it can be done without a second incident. Do not pull. First aid. Notify the site and the employer. Hold the scene.
