Product Introduction

Gantry cranes or Goliath Cranes are very versatile cranes used typically for activities in steel warehouse, precast yards, construction sites, port, train station, powe plant and other outdoor applications.

Include single girder gantry crane, double girder gantry crane, semi gantry crane, trussed gantry crane. Suitable for indoor and outdoor usage.

These cranes can be completely customized for SWL, span, lifting height, speeds, control method and class of duty to suit the actual applications.

In general, truss gantry crane have three kinds of uses.:

First, trussed gantry crane usually used in concrete beam yard, for lift beam girder which is used in bridge build.
Second, trussed gantry crane will used near to the bridge approach, for construct bridge approach, after finished, engineer gantry crane also for lift concrete beam from ground transporter to bridge transporter, help launcher crane to build the whole bridge.
Third, engineer gantry crane is used for disassemble and re erect launcher crane.

In order to facilitate move the gantry crane from one erect point to next erect point and save cost, usually, we will provide moveable steel box foundation for engineer gantry crane.

Technical Features

Gantry cranes are more quickly and easily for installed and disassembled, it is ideal choice for use in a rented factory or in multiple work place
Equipped with all the necessary safety device： overload limit switch, travel limit switch, height limit switch, hook safety latch
High reliability component:hook, winch, drum, wheel, motor etc
High work duty, can bearing heavy capacity and longer span
Needn’t any column, runway beam, just travel on the ground's rail
Suit for both of outdoor and indoor
Trussed structure is best choice for open yeard.

Safety Feature

No.	Safety Measures	Foundation
1.	Loss of pressure fault phase protection	When the voltage is too low, the electricity will disconnect. When the phase is changes, the electricity will disconnect.
2.	Over voltage or over current protection	When the voltage is too big, the electricity will disconnect. When the current is too big, the electricity will disconnect.
3.	Overload limit switch	1. When the lift capacity is more than the max rated lift capacity, the electricity will disconnect, crane will stop work.
4.	Weight limit	Supervise the decrease of hook. There is a limit height. The hook cannot fall any more if reach this limit.
5.	Fire limit	Supervise the up and down limit position of Hook. Avoid the over increase and over decrease, protect hoist.
6.	Crane travel limit switch	Supervise the travel of crane, and stop crane travel more than rated travel distance.
