USA-based The Caldwell Group has launched a custom lifting beam for applications where a crane cannot be positioned over a load due to limited travel or obstructions.
The Overhang Llifting Beam has a counterweight system that can move or be held in a fixed position; movement is powered or manual – although Caldwell recommends using a powered trolley if several lifts per day are required.
“There are a multitude of applications, such as lifting components during equipment maintenance; placing a load onto, say, the third floor of a building in a construction environment; or lifting a partial width roll of material where a monorail crane is centred for full rolls,” said Dan Mongan, senior sales engineer at Caldwell. “We anticipate finding other uses for the beam once word spreads.”
Each system is manufactured for a specific application; the largest to date has been 10,000 lbs. capacity. Customers can request the auto-leveller feature, taken from Caldwell’s Posi-Turner, which is designed to rotate bulky and hard to handle objects during manufacture or assembly processes.
The auto-leveller version senses when a load is out of level, informs the control system and energises the motor to move the trolley, enabling the operator to focus on crane operation. The auto-leveller can be turned off if required.
