The Timars Gravity Centraliser the crane operator is able to adjust and set a correct lifting point to ensure the cargo is handled in a safe and correct way. This means a reduced risk of jammed containers in cell guides and collisions due to side way movements from uneven loads. The Centraliser can operate with any brand of fixed frame 20ft or 40ft container spreaders. The centraliser has an extremely low tare weight of only 425 kg.

​

The Centraliser is equipped with 2 x master links 400x200x50 50T (grade 8) and 2 x shackles KL-8 M42 40T (grade 8) for attaching to the crane twin-hook.

​

The attachment to the fixed frame spreader is via a 32mm chain, grade 8, The chain is 2976 mm long (the chain is used to provide load centralising) and is supplied with anchor shackle KL-8 M42 40T to each end, connected to 2 x 2-part wire slings to the spreader.

​

Safety Wheel Blocking system (SWB-system): 
The chain wheel has a patent pending integrated safety wheel blocking system that automatically prevents the chain wheel from turning when the main sling/chains are under tension from the load. 

In order for the crane operator to change the lifting position, the lowering of the gravity Centraliser will provide slackness to the chain. Then the chain wheel will be unblocked and the lifting point can be changed by slewing the crane and passing chain through the chain wheel until the correct position is obtained.
