SAFE OPERATION
3.2
SAFETY EQUIPMENT - PPE
Safe systems of work should be appropriate for the working conditions that the hoist is being used in with method statements stating what
the hoist is being used for, the authorisation of staff to operate hoists and the PPE requirements in place. In general overalls, safety shoes,
hearing protection and gloves are normal but other sites will require safety glasses and hard hats.
3.3
LIFTING GEAR BELOW THE HOIST
Where lifting gear is connected into the bottom hook of the hoist it should be sized for at least the capacity of the hoist and physically fit well
into the body of the hook allowing the safety catch to close.
Where a larger item such as a spreader beam is used this may have an effect on the lifting capacity of the hoist, so the SWL should be
reduced to reflect this.
3.4
MOUNTING ON TROLLEYS
▪
Ensure that the trolley is properly mounted on the beam and set correctly for the beam with adequate wheel clearance.
▪
Ensure that the stops for the trolley mounted on the runway beam are correctly positioned and securely installed.
▪
Ensure that the top hook or link plate of the hoist fits properly on the suspension point of the trolley and is assembled properly
with the hoist at the centre of the load bar.
▪
Ensure that the load bar and tie bar nut have been secured and the trolley side plates are set parallel to the beam web.
▪
Ensure that the tie bars are correctly adjusted in the slots with the anti-tilt roller close under the beam with enough clearance to
allow the trolley to run along the beam.
3.5
OPERATIONAL BREAKDOWN OR ACCIDENT
If an unloaded hoist stops working then it should be removed from location and sent for repair if none of the remedies in the trouble
shooting guide have an effect.
When the hoist is still holding a load then an additional hoist should be used to take the weight of the load so it can be safely lowered and
the faulty hoist removed for repair. If another hoist cannot be used to lower the load it is possible to release the brake by slackening the
brake cover screws but this should only be done by a RRL engineer or after discussions with Red Rooster as it is not always possible or
safe to do so.
The main air supply line to the hoist should be fitted with an easily accessible valve to cut off the air supply to the hoist in case of
emergency or for maintenance. Pendant control hoists also have a main air shut off valve.
There should be a safe access to the hoist to carry out maintenance, inspection and lubrication.
