Key Advantages of LDZ Single Girder Grab Overhead Crane
1. Handles Many Materials
This crane works well with bulk materials like coal, grain, and scrap metal. It can use different tools such as grabs, spreaders, suction cups, and chains. It is good for waste recycling, foundries, and ports because it can handle many types of loads.
2. Light but Strong
The single girder design makes the crane lighter but still strong and stable. It works best for light to medium loads and has an efficient electric grab system.
3. Saves Space
The crane runs on high rails (mounted on concrete or steel supports). This keeps the ground clear for cargo or workers. It moves along the rails to cover the whole work area without blocking the floor.
4. Flexible Controls
You can control the crane in two ways:
From the ground (remote or pendant) for safety in dangerous areas.
From an air cabin (open or closed) placed on the left or right. The cabin can be entered from the side or end to fit different workspaces.
5. Strong and Durable
Main beam: Made of U-shaped steel and I-beam for strength without extra weight.
End beams: Box-shaped welded steel for durability and even load support.
Track options: Can be welded, bolted, or fixed with hook bolts to match site needs.
6. Smooth Movement
Uses soft-start motors and disc brakes for jerk-free operation.
Travels at 20–30 m/min for fast material handling.
Hoist and crane movements are controlled separately.
7. High-Quality Electrical Parts
Uses top international electrical brands for long life and less downtime. Power is supplied through seamless sliding lines for steady performance.
8. Efficient Lifting
The conical rotor motor gives high starting torque for heavy grabs. The lightweight grab system saves energy while keeping precision.
9. Easy and Cheap to Maintain
The single girder design costs less to install and maintain than double girder cranes. Bolted parts make repairs and replacements easy.

Warehouses
Steel plants
Ports and logistics centers

How Grab Bridge Cranes Work
A grab bridge crane uses a grab as its lifting tool. It can unload, stack, transport, and feed materials. It is widely used in factories for general lifting and special tasks with grabs.
Structure
Main parts: Box-shaped bridge, grab trolley, trolley movement system, driver’s cabin, and electrical controls.
Grab: A tool to pick up loose materials.
Operation
The grab has two systems: one to open/close and one to lift.
Four steel ropes connect to these systems.
To grab material, the close system shuts the grab. Then the lift system raises it evenly.
To unload, the open system releases the material.
Differences from Hook Cranes
Except for the lift system, grab cranes are similar to hook cranes.
