   • Applications: Warehousing, manufacturing, construction.
2. Winches:
   • Function: Used to pull or lift loads horizontally.
   • Types: Manual winches, electric winches, hydraulic winches.
   • Applications: Marine, construction, off-road recovery.
3. Slings:
   • Function: Used in conjunction with lifting devices to secure loads.
   • Types: Web slings, chain slings, wire rope slings.
   • Applications: Various industries including construction, shipping, and manufacturing.
4. Jacks:
   • Function: Used to lift heavy objects a short distance.
   • Types: Hydraulic jacks, mechanical jacks, pneumatic jacks.
   • Applications: Automotive, industrial maintenance, construction.
5. Lifting Beams and Spreaders:
   • Function: Distribute the load evenly when lifting with a crane.
   • Applications: Heavy lifting in construction, manufacturing, and shipping.

Cranes

Types of Cranes:

1. Mobile Cranes:
   • Function: Portable and can be moved to different locations.
   • Types: Truck-mounted cranes, rough terrain cranes, all-terrain cranes.
   • Applications: Construction, infrastructure projects, logistics.
2. Tower Cranes:
   • Function: Fixed cranes with a long horizontal jib, commonly used in the construction of tall buildings.
   • Applications: High-rise building construction.
3. Overhead Cranes:
   • Function: Fixed installation cranes that move along tracks installed on the ceiling.
   • Types: Single girder, double girder.
   • Applications: Manufacturing, warehousing.
4. Gantry Cranes:
   • Function: Similar to overhead cranes but supported by freestanding legs.
   • Types: Full gantry, semi-gantry, portable gantry.
   • Applications: Shipyards, rail yards, manufacturing.
5. Jib Cranes:
   • Function: Have a horizontal arm (jib) that supports a moveable hoist.
   • Applications: Workshops, industrial facilities, maritime.
6. Crawler Cranes:
   • Function: Mobile cranes mounted on a set of tracks (crawlers).
   • Applications: Heavy lifting in construction, particularly on soft ground.
