Salient Features and Advantages of Wire Rope Hoist

An electric wire rope hoist is designed for safe lifting and pulling of a load. It is a major element of a typical crane system and possesses a compact design with a strong working load range to fit in multiple flange widths. These hoists are available in different versions like standard crab unit to carry medium standard weight limits, side mounted hoist for the highest hook position, monorail hoist with twin trolleys for long hook paths and a low headroom crab to use in less space.

Advantages of Wire Rope Hoist

• Modern appearance with smooth finish.
• Best-suited for multiple applications.
• Load damage can be reduced.
• Precise and safe lifting and lowering.
• Smooth acceleration is guaranteed without load swing.
• Beam size has been reduced by low flange bending stress.
• Three-wheeling has been minimised for durability and more power transmission.

Plentiful Features that Wire Rope Hoist Offers

1. Secured with a wire rope drum, the hoists have 3 heavy ductile iron clamps with additional wire rope wraps on the drum.
2. Easy and quick load holding with heavy-duty disk brakes.
3. Steel compound tread wheels that can be used on either ‘S’ beams or wide-flange for long life. One wheel is positioned on each side of trolley for positive tracking.
4. A trolley enables smooth adjustment with multiple beam flange widths.
5. Lower block with a low-headroom design for maximum lift.
6. Heavy steel frame allows robust foundation and positive alignment of key components.
7. Triple reduction hoist gearing with oil bath lubrication enclosed within a cast aluminium oil tight gear case.
8. A bearing mounted trunnion hook with 360° rotation and 180° back and forth swing for easy adjustment of load.
9. A typical wire rope hoist has one lower and two upper geared limit switches that are flexible to use and allows positive stop to a load in the directions of hoisting and lowering.

Some Major Characteristics

1. 
   
2. The multi-pin plugs and socket connections results in control boxes and motor power connections with push-button control cable and festooned terminations. Fast detachment are vibration and moisture-resistant, dust sealed and of premium quality.
3. A fragile electro-mechanical device for overload that prevents hoists from being overloaded.
4. Hardened wheels, direct drive with rotating axle, articulating end trucks and sealed lubricated bearings.
5. The magnetic actuated and self-compensating motor brakes are applied during power failure. These brakes are asbestos-free with non-polluting linings.
6. The lifetime lubricated gear trains and bearings are hardened and evenly polished.
7. Drive pinions and steel wheels with a broad and large diameter.
8. Heavy-duty squirrel cage gear motor with low torque, high inertia and variable frequency drive standard.

Grasping the above features of a wire rope hoist can guarantee you the best performance at different lifting operations. Depending on how much space you have and how much weight you need to carry, the desired hoist type can be picked for good results.
