INTRODUCTIONS

            VA Lever Hoists are kind of portable and versatile hand -operated loading and pulling appliance, light and small, multi-purpose manual lifting equipment, whch have exceptional advantages particularly for pulling in every limited narrow places, in the upper air high above the ground and at any angles. With compact design and robust, deep drawn, stamped steel construction, high quality materials ensure light weight without infringing reliability, VA lever hoists require small lever forces even at full load and the can provide excellent performance for lifting.

           VA lever hoists adopt Japan manufacturing technology, which shows perfect performance and longevity.

           VA lever hoists are equipped with heat treated steel plates, gears and shafts for enhanced strength; forged bupper, lower hooks with forged steel safety latches and high tensile alloy steel chain. They have tight structure and graceful outline so they enjoy great reputation among markets. What’s more, people can operate it easily even in narrow place. The whole hoists are made of high strength low carbon alloy steel which is sturdy, corrosion-resistant and durable. Within auto-clutch, worker can handle the load chain with one hand when there is No-Load.

           The load chain wheel of VA lever hoists is made of  high quality alloy with precision machining process. So the load chain and the wheel work smoothly. The braking mechanism, which makes up heart of the hoist, is enclosed in a double cover: the wheel and the brake covers. These protective covers not only keep out weather elements but also help to prevent mud and dust from entering internal mechanisms, which make blocks high durability and high safety. The lever hoists have fine and elegant appearance but hard and can resist crash, and not easily to break. Thanks to the newly designed forged hooks, the top hook is quite safe, and it has the quality of sowing bending, which  ensure thay they will not break suddenly when the overload appers and ensure the safety of operators.

            VA lever hoists are produced and inspected strictly by international standard, which ensures the longevity and quality of the electric hoists. The surface of the metal sleeve is hardened and grinded to improve the mechanical efficiency and reduce the strength of the hand lever. The rubber covered handle grip are comfortable to operate, and labor-saving, the special texture of grip prevent gripping. All design adopts the advanced precise construction, and accord to the human. VA lever hoists have compact short handle design, but it also keeps the hand lever operation which saves a lot of effort. It is an ideal tool for building and general industrial users, especially suitable for use in restricted space.Cause the high quality alloy steel, they are durable. The maintenance of our products is available and we provide with operators with complete after-sale service.

           They are widely applied in construction sites, factories, mines, farms, agricultural production, and in wharfs, power plants, shipyard, boat manufacturing, docks and storages for fixing machines, lifting cargos, and loading and unloading goods, installing equipment, tightening goods, dragging loads, and they are especially advantageous for lifting work in the open air and places where no power supply is available, narrow space, open air and over-head places for pulling and stretching at angle and can be attached to a trolley of any type as a traveling chain block.

           They are also called VA series lever chain blocks, high quality VA blocks, VA type hand lever blocks, VA manual chain lever hoists, VA manual lifting lever hoists, VA lever manual lifting equipment, VA vertical lever stand chain blocks, hand chain lever hoists, VA lever chain hoists. 3/4 ton, 1/2 ton, 1 ton, 2 ton and 3 ton are most choosen by customers.

Detailed Description

1. Hook
         After forging, it will not break. The lower one can rotate 360 degree, which has safe insurance to ensure safety. Both hooks adopt high quality and high intensity material. The top and bottom hook are made of forged high strength alloy, accomplished by heat treatment process. The hooks also have three stretch indicators. However if by any chance the hook is overloaded there is no fear of it breaking, it will simply gradually start straightening out, avoiding any load drop or personal injury. The design of the bottom hook, with relatively large dimensions, makes it easy to stabilize a load in proper position.
