Rope reeving
Winches are reeved from 2parts to 16parts depending of the capacity. Rope are selected
according to FEM standards. Elimination of reverse bends minimize rope wear. Stable positioning of the load is attained with true vertical lift. Accessible rope dead end allow the rope to be easily adjustable and replaced.
 
Extended Speed Range(ESR)
The use of Dawson’ Hoist frequency controls enables the use of the ESR option. This feature allows operation at speeds up to 200% of nominal with reduced load (maximum of 20% of rated load)

 

Auxiliary hoist
Adding a special tow trolley can provide an auxiliary hoist. The tow trolley is connected to the main unit by pinned connections, This arrangement ensures optimal hook approaches.

 

Optional rope guide
A rugged rope guide ensures proper rope winding on the drum. Upper and lower limits are adjusted with rotating limit switch. Process limits added with rotating limit switch.

A wire rope hoist is a hoist that utilizes wire rope as the lifting medium. 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 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. 
Selection Criteria

 

The size of the hoist is determined by the load spectrum, average operating time, safe working load and rope revving.

 

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 ?
