Brief Introduction

Girder machine is a specially designed for bridge construction of a gantry crane.Truss girder machine is mainly composed

of main girder, leg, crown, etc, with pin shaft and highstrength bolt connections between components, easy installation, and transportation; Compared with the ordinary gantry crane, installation fast and convenient,more conomical and practical.It is

widely used in the bridge construction.

Advantage and Components

Advantage

Gantry cranes have advantages such as highusage of area, large working area,

widely application, high optimized for general use;

it’s widely used at seaport working yards and outdoor storage nowadays.

Components

a) Steel structure: main bridge beam, ground beams with wheels driven by motors.

b) Hoisting mechanism: electric winch and trolley mounted on main bridge beam.

c) Electrics: electric box/cables/operator.
