Heavy duty Industrial Manual Lever Block
Lever blocks are a versatile lifting & tensioning device widely used in rigging, construction & mining.
Lever blocks can be used in any direction but must be in a straight line.
The Beaver lever block has a chain guide fitted in order to stop the load from jumping out of the pockets on the load sprocket.
The Beaver 3S Industrial Chain Lever Block mechanism and gears are enclosed in a robust all steel compact shell.
The load chain is made of high resistance, Grade 80 Alloy Steel, black finish, heat-treated, calibrated and marked according to International Standards ISO 3077 and ISO 1834.
All Beaver lever block gears are fitted with industrial Roller bearings.
The short arm lever and the gear ratio allows minimum effort to raise maximum load with maximum security.
The top and bottom hooks come complete with cast latches.
Top and bottom hooks are fitted with ball bearings to allow rotation under load.
Ergonomic and heavy free knob to ensure easy and convenient handling.
Machined and heat-treated gears, offering better durability and longer life cycle.
Every Beaver 3S Industrial Lever Block is operationally tested to its rated capacity and is supplied with a Beaver test certificate, relating to its stamped identification side plate.
Beaver ‘ID’ plates and rivets are supplied in stainless steel (a non-conductive material) in order to avoid dangerous sparking, making them ideal for underground mining.
A comprehensive range of spare parts are available, complete with full repair facilities and re- testing to Australian Standard specifications.
