Double Girder Electric Wire Rope Hoists SHA Type
Electric dual rail built-up hoist trolley hoist is typically used for double girder cranes with heavy capacity available.
Nante can provide double girder trolley crab hoist with stability and good performance. A heavy capacity wire rope hoist is a hoist that utilizes wire rope as the lifting medium. Usually with heavier loads, we adopt steady and tough material for the trolley frame. It is often powered electrically or pneumatically. This lifting device is made up of a rope storage drum, motor(s), gear box and braking system, and is suspended from a monorail or bridge beam(s) by means of a trolley. It may also be stationary mounted.
A overhead crane is a machine used for lifting and lowering a load, and moving it horizontally. A crane's drives may be manual, powered or a combination of both. Cranes are typically used when there is insufficient (or intermittent) flow volume such that the use of a conveyor cannot be justified. They provide more flexibility in movement than conveyors, and less flexibility in movement than industrial trucks. Loads handled by cranes are more varied with respect to their shape and weight than those handled by a conveyor. Most cranes utilize hoists for vertical movement, although manipulators can be used if precise positioning of the load is required.
Many different types of cranes are used for material handling applications. These include overhead cranes as well as cherry picker type boom lifts, mobile and self-propelled cranes, straddle and counterbalanced (cantilevered) cranes. Portable and mobile floor cranes can be equipped with fixed or telescopic booms as well as mast rotation when equipped with outriggers. Lifting can be performed with the boom itself or a winch operated cable lift.
The size of the hoist is determined by the load spectrum, average operating time, safe working load and rope reeving.
1. What are the operating conditions ?
2. What is the specified safe working load ?
3. To what height must the load be lifted ?
4. What is the required lifting speed ?
5. Do the loads need to be lifted and lowered with great accuracy ?
6. Is horizontal load travel necessary ?
7. How the hoist to be controlled ?
Whether chain hoist or wire rope hoist, electric or pneumatic; our line of powered hoists are ideal in manufacturing, power generation, and industrial facilities where heavy items are lifted and positioned as part of production or warehousing. Our new model high-capacity wire rope hoist complements our line with capacities up to 50 Tons. We offer a full line of manual hoists, both hand chain and lever tools, which are used primarily for maintenance and construction activities.
