product superiority of 20tons Electric Hoist Box type Single Girder Gantry Crane A3 A4
The gantry structure is divided into two types: box-shaped and truss. The box-shaped technology is good and easy to manufacture; the truss has light weight and strong wind resistance. The whole machine has the characteristics of light weight, simple structure, convenient installation and maintenance, etc. It is suitable for outdoor places such as factories and mines, freight yards and warehouses within the range of small and medium lifting weights for general loading and unloading.Multifunctional box gantry crane are suitable for general loading and unloading in outdoor places such as factories, mines, cargo yards and warehouses within the range of small and medium lifting capacities. It is forbidden to work in an environment full of flammable, explosive and corrosive gases.
Multifunctional box gantry cranes are usually cheaper than truss gantry cranes because:
1. Compact structure, small size, easy to ship and low freight
2. Exquisite design and easy installation
3. Mature production technology, shorter construction period
4. Continuously reform technology, save manufacturing costs, and lower product prices
The multi-functional box gantry crane has reliable safety performance, and has safety configurations such as weight overload protection device, crane travel limit switch, low voltage protection function, emergency stop system, current overload protection function, etc.
