Launching Gantry Crane

Bridge gantry crane

Launching Gantry Crane is mainly used for lifting equipment in the construction of railways, highways and bridges. Because the position is not fixed and the walking is relatively large, the connecting parts are connected in the form of connecting rods, which are easy to disassemble and transport.

Launching Gantry Crane mainly include Bridge Building Crane, Bridge launching gantry Crane, and Girder Launcher.

Launching crane is mainly used for general loading and unloading and intermediate handling in construction plants such as roads, bridges, and power plants.

Types and features of launching portable gantry crane

Features of girder launcher

Unique pin connection, firm and reliable, easy to install.

A-type fracture surface, continuous girder with low center of gravity, convenient and reliable.

The machine can accomplish the build of girders with carrying and erection at the same time.

Low deflection and high stiffness.

Safe and reliable, High efficiency.

Safety Features

Safety is the most important issue for cranes. To ensure the safety,the following safety devices are equipped in BL crane.

Crane traveling limit switch.

Overload protection device.

Lifting height limit device.

Voltage lower protection function .

Phase sequence protection function.

Emergency stop function.

Rain cover for outside hoist, driving units, electric cubicle.

Warning indicator : flashing nights and warning sounds.

Wire-less infra-detector for anti-collusion.

Features of Bridge Building Crane

1. Horizontal operation landing the beam in place at one time;

2. Suitable for the construction of inclined(curved)bridge;

3. Light weight, convenient and quick transportation, installation and removal;

4. Safe and reliable work, small longitudinal cantilever deflection;

5. The legs are not landed on bridge deck when longitudinal moving, reducing the pressure on the beam/bridge deck.

Features of Bridge launching gantry Crane

1. The crane adopts colloidal pin wheel reducer, soft start motor and eight wheel four-way drive, which has stable operation and high safety.

2. Good crane height design, large operation area of trolley mechanism and high utilization rate of enterprise plant.

3. Stable structure, light weight of the whole machine, reasonable drum diameter, pulley block magnification and reducer support structure

4. High precision electrical management, AC variable frequency speed regulation + PLC program control, mechanical and electrical protection devices

5. Serial and modular design.

6. Frequency conversion management, stable starting and braking, swing prevention technology, and safer lifting of goods.
