GETTING STARTED - INSTALLATION & TECHNICAL CHARACTERISTICS
1.4
CLOSE HEADROOM WORKING
The lower hook of the TCR / TCS / TMH hoist includes a swivel arrangement. This allows the load to turn without twisting the chain.
However, when repeatedly handling loads with the bottom hook close to the hoist, especially when rotation of the load is prevented, there is
tendency for the chain to attempt to enter the guide at an angle. This is particularly pronounced on two fall units. If this problem is noticed when
doing a trial lift, a high quality ball bearing swivel should be mounted below the bottom hook of the hoist.
CHAIN COLLECTORS
If the hoist has been supplied with a chain collector bag or bucket, and the chain has been stored within it during shipment, remove all the
chain from the collector by hand, and remove any knots or twists.
In all cases carefully feed the chain over the load wheel allowing it to fill the collector without any interference as it emerges from the wheel.
This way the collector will fill normally. If the chain within the collector is disturbed great care must be taken the next time that the chain is fed
out of the collector to ensure that it is not twisted or knotted. Chain bags and buckets are fitted with one or two brackets depending on the
model and HOL of the hoist.
See additional instructions (Section 6) for large collectors.

TECHNICAL CHARACTERISTICS
The WLL of the hoist and trolley will be marked on the hoist / trolley name plate and also in the hoist specification supplied.
The reactions on the powered hoist on the support, runway beam or crane should have been taken into account in the design of the structure.
The structure should be at least 25% stronger than when using manual equipment due to the shock loading applied by the operational speeds
and the starting and stopping of the hoist.
All Red Rooster hoists are fitted with the following safety features
▪
Overload limiter
▪
Upper and lower mechanically operated travel limits. These are ultimate stops and should not be used to stop the hoist on a regular
basis.
▪
The disc brake is spring applied so when the controls are not operated or in the event of loss of air supply the brake is applied
holding the load in position.
▪
On pendant controlled hoists an emergency stop button is fitted which connects to a normally open valve either located in the hoist
valve chamber or connected to the hoist. When the emergency stop button is pushed or if the air supply to the hoist is cut off then
the valve will close stopping the hoist.
▪
Red Rooster hoists have a 5:1 factor of safety.
