Simulation Phases
Equipment Details
Come-A-Long / Lever Hoist
A manual lever-operated hoist used for pulling, tensioning, and aligning loads. Unlike chain blocks, come-a-longs are primarily used horizontally for straightening structural members.
Key Components
Lever handle with ratchet mechanism
Load chain with calibrated links
Top hook (anchor point connection)
Bottom hook (load connection)
Free-wheel selector (engage/disengage)
Clutch / Ratchet Mechanism
How the Clutch Works
The free-wheel selector controls chain direction. In ENGAGE position, lever pumping pulls the chain and the ratchet holds tension between strokes. In RELEASE position, the ratchet disengages allowing the chain to run free. This simulation demonstrates both modes.
Pre-Use Checks
⚠ Mandatory Inspection
Before each use: Check chain for wear, twists & damage. Inspect hooks for cracks & safety latch operation. Verify WLL tag is legible. Confirm ratchet engages properly. Test free-wheel function.
Safety Requirements

AS 1418.2 – Serial hoists and winches
AS 4991 – Lifting devices
AS 2550 – Safe use of cranes
WHS Regulations – High Risk Work
⚠ Critical Safety Rules
Never exceed rated WLL. Never use as a crane or vertical lift unless rated. Always ensure load path is clear. Use tag lines where required. Inspect before every use. Remove from service if damaged.
