Launching Gantry Crane
Hoist & Crane Trolley
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 Gantry Crane is mainly used for general loading and unloading and intermediate handling in construction plants such as roads, bridges, and power plants.
|Launching gantry crane types||Structure||Feature||Parameter|
|Bridge launching gantry crane||Composed of gantry, winch trolley, crane operating mechanism, driver's cab and electrical control system||Slow working speed, truss gantry, light structure, strong wind resistance，closed cab||Lifting capacity：＜200ton crane,|
|Bridge building crane||Composed of machine arm, crane trolley, outrigger, hydraulic system, electrical system, generator set, and safety monitoring system.||Lifting transportation beam, longitudinal movement, variable frequency walking mechanism, high mechanization||Lifting capacity:450t-900t, 500 ton Bridge Building crane|
Span：32m, 24m, 20m
|Girder launcher||A gantry crane, composed of assembled main beams, outriggers, trolley||Easy to disassemble, install and transport, economical and practical, high safety performance||Lifting capacity：＜1000ton crane, 450 ton crane, 250 ton crane, 100 ton crane|
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 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.
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.
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.
