Truss crane mainly refers to truss gantry crane which use truss structure, welded from shaped-steel, divided into two working-level mid-level and light-level system according to the busy degree of use. Truss gantry crane is mainly used in factories, open area between fixed cross, construction and installation sites, lumber yards and other places, due to the wind size is smaller than the box-shaped structure. Truss crane is particularly suitable for large sandstorm place, generally for handling and lifting work.
Truss gantry crane main specifications
| Product Type | Truss gantry crane |
|---|---|
| Crane Truss Lifting Capacity | 1~50 t |
| Crane Truss Span Length | 12~35m |

Composition of truss gantry crane
Truss gantry crane is mainly composed of truss girder, legs, lower cross beams and other components, structure components using shaft connecting, easy disassembly and transport.
The whole gantry crane adopts single girder, trolley part using hoist or electric hoist, trolley across the upper part of the main beam, hoisting mechanism lifting rope from both sides of the main beam, which can lift shape large object. All mechanisms operating in the driver’s cabin and all set up with rain cover.

Features of truss gantry crane
Generally, the truss gantry crane has the features such as main structure with light weight, small wheel pressure and reliable performance, evolved by Russian gantry crane. Main specification of the truss gantry crane includes lifting capacity, lifting height, span, mechanism operating speed, working class, truss type gantry crane total weight and wheel load. And the detailed features of the truss crane are as follow:
Lifting capacity of truss gantry crane
The lifting capacity of the russ gantry crane referes to the maximum allowable lifting weight during crane normal work. Commonly has 5ton to 100ton.
Lifting height
The lifting height of the truss gantry crane referes to the distance between spreader upper limit position and lower limit position.
Span of truss gantry crane
The span of truss gantry crane is the distance between the wheel vertical centerline at both sides of the crane.
Truss gantry crane each mechanism operating speed
- Lifting speed: it is the extract device full loaded lifting speed when lifting mechanism motor at rated speed.
- Traveling speed: it is the crane traveling speed when crane traveling mechanism motor at rated speed.
- Trolley traveling speed: it trolley traveling speed when the trolley traveling mechanism motor at rated speed.
Working class
Indicators of the whole crane lifting full load level and lifting numbers degree, truss type gantry crane working class divided into A1-A6(A class correspond to M class) total of six levels, light duty (A1-A3), intermediate duty (A4, A5), heavy duty (A6).

Types of truss gantry crane
For different material handling needs, the truss gantry cranes are designed with different configurations. As for truss gantry cranes, there are mainly single girder crane truss and double girder crane truss, and the both the two types of cranes can also be semi gantry cranes as needed
