INTRODUCTIONS

           Chain Blocks With Geared Trolleys normally refer to ultra low headroom construction manually operated hoist minimizing beam-to-hook distance that use small force to lift, lower, and pull loads, Chain Blocks With Geared Trolleys which have looped hand chain connected to hand chain wheel or sprocket are brilliant for accurate load spotting done, with strength steel construction, premium quality and durability, they are perfectly suited for confined space.

           With a geared beam trolley fitting wide flange or S-type  I-beams coupled with lifting chain block used on overhead equipment beyond  operator’s reach, the load in traversing direction is moved by an operator simply  and the trolley will travel in the opposite direction by pulling a hand chain,  then hand-exerted small force across chain pulley block gears inside the  hoisting unit which facilitate wheel movement to multiply into one large force enough  to raise or lower the designated load, or over a pulley, drum, sheave to  leverage the force strong enough to lift, so heavy loads can be lifted by bottom  load hook attached to a chain, rope, or wire through manual force of worker  using hand chain, when the operator’s hands are released, the load will be held  in place by mechanical disk brakes (Weston-style brakes) which secure the load  once it has been lifted and control the descent of the load when it has been  lowered to make the next pull, safety catches is included in both top and  bottom hooks to ensure the load and the hoist is secure once suspended and  lifting.

           Although test load is 1.5 time of rated load, we still suggest  customer to use within maximum rated load and operators should never attempt to  lift a load heavier than it, 

           Headroom is the distance from the bottom  of the load hook to the top of the hoist, it is “H” in the diagram on above PDF down load file and is the minimum vertical space needed for chain block to hang freely and operate correctly. 

           Lift is the maximum vertical distance for moving a load by hook, if lifting height is 3m, normally manufacture needs 3.7-3.8m loading chain for one loop since extra chain is inside the chain pulley block.

           Pull force describes the force needed to lift a load. If a 1 tonne chain block specifies a pull force of 304N, then  operator needs to be able to pull a 304N weight in order to lift the maximum 1 ton  load. 

           Chain pulley Block With Geared Trolley is  a tool integrating low headroom manual trolley or manual-chain operated gear  trolley making it ideal for applications where longer hook travel is required  that widely used in maintenance, production processes, construction, transportation,  mining, manufacturing and other material handling industries and low headroom  for work in tight spaces, please contact RAMHOIST in advance if you want hand  geared trolley hoist to suit in hazardous environments.

           They are also called Manual chain hoist with geared trolley, Geared trolley chain blocks, Manual hoist With Geared Trolley, hand chain hoist and geared trolley, hand geared trolley hoists, Monorail trolley hand chain hoists, Trolley mounted hoist, geared travel monorail hoists, chain travel monorail hoists, Monorail trolley mounted hand chain hoists, manual geared trolley hoist, chain hoist geared trolley, push pull trolley hoist, Pull travel hand chain hoist, Chain travel hoist, Geared hand chain block, Extra low headroom chain hoist (Gear and push travel), Compact trolley hoist (Push and geared travel), Low Headroom Hand Chain Hoist, Ultra low trolley hoist, low headroom combination chain hoist/trolley, push hand combination chain hoist and trolley mount, triple spur gear chain pulley block, lifting gear chain block and spur gear chain block.

           Default one is refer to above low headroom, but chain block can also assemble with normal Geared trolley with much lower price, Please keep me informed when you place order.

Technical info

China Chain Blocks With Geared Trolley.jpg

Chain Blocks With Geared Trolley is a very compact trolley lifting device, it includes an applicance with pull cart intergration chain hoist. One of the most important factor is the hook can increase to just close to the beam flange.

The device is composed of solid steel into a gourd accessories with high quality. Suitable for horizontal beam or model of the beam wing edge spherical profile wheels, EN818-7 standard high strength galvanized lifting chain, 3m hoisting height standard lifting chain and operating hand zipper length of 2.5m.

It is ideal for applications where longer hook travel is required,also ideal for demanding industrial lifting applications within confined spaces.
