Duties of crane operator
Personal protective equipment to be provided by the user
See chapter 2, Safety instructions.
Requirements for workplace
•
The operator must not stand in the hazard area.
•
The hazard area must be clearly visible.
•
The movement of the load in all directions must be clearly visible.
WARNING
Danger of bodily injury
When working with chain hoists, the following points must be observed:
•
The crane operator must observe the load, or if the crane is unloaded, the load
suspension equipment during all movements of the crane if they could cause danger.
If it is not possible to observe the crane, the crane operator may only control the
crane by following signals from a signaller.
•
Wear ear protectors in noisy environments.
•
Start lifting load with the slowest hoisting speed.
•
The crane operator must give warning signals as necessary.
•
Loads attached by hand may only be moved by the crane operator after an un-
ambiguous signal from the person attaching the load, the signaller or another person
responsible appointed by the user. If signals need to be used to communicate with
the crane operator they must be agreed between the person responsible and the
crane operator before being used.
•
Every day before starting work, check brakes and limit switches and inspect the
system for any visible defects.
•
Stop working with the crane if there are any defects which might prejudice its safety in
operation.
•
At close of work, secure cranes which are exposed to wind with the wind safeguard
mechanism.
•
Do not move loads above people.
•
Before starting work, ensure there is sufficient workspace.
•
Do not leave suspended loads unattended, the control pendant must be within easy
reach.
•
The slipping clutch is a safety device. It must not be activated in normal operation.
•
Do not load above the permitted maximum working load.
•
Pulling loads at angles, dragging loads, or towing vehicles with the load or load
suspension equipment is forbidden!
•
If the chain is slack, tauten it at minimum speed before lifting.
•
Do not jerk free any loads which are jammed.
•
Do not place your hands between edges which could pinch or cut.
•
Approach final positions for hoisting, lowering and travel in normal operation only if an
operational hoist limit switch is fitted.
•
Inching operation (repeated brief activation of the motor to achieve small movements)
is not permissible. Motors and brakes could be subjected to an impermissible temper-
ature rise. This would lead to the temperature control disconnecting and the load
could then not be set down for some time. Switchgear and motors could be damaged.
•
Do not move in the opposite direction until the hoist has come to a stop.
•
Observe the safety instructions, see chapter 2
