Abstract

A lifting beam for picking up sheets by suction has all the necessary controls provided on it, can be connected to a hoist or the forks of a fork lift truck and is battery operated to avoid the need to connect to any external power source. Preferably, control and non-return valves and vacuum sensors are provided.

Description

BATLIFT' DESCRIPTION
2337982 THIS INVENTION RELATES TO A BATLIEFT - BATTERY OPERATED VACUUM LIFTLNG BEAM.
USERS OF STEEL/ALLOY PLATES & SHEETS FREQUENTLY EMPLOY A FORKLIFT TRUCK FOR GENERAL HANDLING OF PLATE/SHEET MATERIALS. THE MAIN DRAW BACK OF THE FORKLIFT IS THAT FORKS HAVE TO BE APPLIED TO THE UNDERSIDE OF THE MATERIAL BEING LIFTED, OFTEN CAUSING DAMAGE AND NECESSITATING USE OF WOODEN SPACERS OR SIMILAR TO ALLOW FORK ACCESS.
ACCORDING TO THE PRESENT INVENTION WE PROVIDE A STRUCTURAL LIFTING BEAM/RESERVOIER COMBINATION EQU1PPED WITH 2 OFF SUCTION PADS AND VACUUM PUMP. THE BEAM IS PROVIDED WITH 2 OFF FORK SHOES FOR LOCATING OF FORK LIFT TRUCK FORKS.
A SPECIFIC EMBOD1EMENT OF THE INVENTION WILL NOW BE DESCRIBED BY WAY OF EXAMPLE WITH REFERENCE TO THE ACCOMPANYING DRAWING ENTITLED' BATLIFT TYPE 500' THE DRAWING SHOWS A SQUARE STRUCTURAL SECTION RESERVOUPLIBEAM WITH BATTERY PACK/ PUMPISENSORS AND ALL OTHER COMPONENTS MOUNTED ON THE SYSTEM. 2 OFF SUCTIONPADS ARE ALSO MOUNTED ON THE UNIT.
THE BATLI1FT IS SWITCHED ON VIA INTEGRAL CONTROL PANEL AND THE VACUUM PUMP THEN STARTS TO EVACUATE AIR FROM THE RESERVOIR. THE VACUUM LEVEL IS MONITORED BY 2 OFF VACUUM SWITCH WHICH ENSURES ADEQUATE RESERVOIR VACUUM PRIOR AND DURING OPERATION. ONCE ADEQUATE VACUUM IS ACHIEVED THE RED WARNING INDICATOR LOCATED ON TOP OF THE CONTROL BOX WILL STOP FLASHING THE UNIT IS NOW READY FOR USE. THE FORK LIFT OPERATOR LOCATES HIS FORKS INSIDE THE FORK SHOES AND TIGHTENS THE RETAINING BOLTS LOCATED WITHIN THE FORK SHOES. THE BATLIFT IS NOW AN INTEGRAL EXTENSION OF THE'FORK LIFT FORKS AND THE OPERATOR PLACES THE LIFT BEAM ON THE PLATE/SKEET TO BE HANDLED - OPERATES THE CONTROL VALVE - VACUUM LIFTING FORCE IS THEN APPLED VIA THE 2 OFF V45145 SUCTION PADS ONTO THE TOP SURFACE OF THE TARGET PLATE/SHEET. THE OPERATOR THEN RAISES HIS FORKS AND THE PLATE/SHEET IS LIFTED.
