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.YFjHenan Weihua Machinery Co., Ltd

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.YFjHenan Weihua Machinery Co., Ltd

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.YFjHenan Weihua Machinery Co., Ltd

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:YFjHenan Weihua Machinery Co., Ltd

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.YFjHenan Weihua Machinery Co., Ltd

Lifting height

The lifting height of the truss gantry crane referes to the distance between spreader upper limit position and lower limit position.YFjHenan Weihua Machinery Co., Ltd

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.YFjHenan Weihua Machinery Co., Ltd

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).YFjHenan Weihua Machinery Co., Ltd

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 neededYFjHenan Weihua Machinery Co., Ltd

Single Girder truss gantry crane 

Single girder crane truss refers to the gantry crane with one truss main girder and used with CD or MD type electric hoist to lift heavy goods. The single girder crane truss can be applied on many different work occasions, such as port, shipyard, railway line and material yard. Truss semi gantry crane only has two support legs on the one end and the other end of the crane needs support from building or other structures, and it can travel along the track.YFjHenan Weihua Machinery Co., Ltd

Features of single girder truss gantry crane

• The structure of main girder is triangular truss, which strengthens the whole structure, lightens the weight, and enhances wind resistance. Wind resistance is class 6, non-working wind resistance is 11;
• Thermal expansion seamless steel legs are jointing with (or truss legs) and the main girder, ground girder by the bolt or pin connections. Stable structure, easy installation and removal.
• The design and manufacture of the truss crannies to meet the national requirements of rules and standards which is effective currently and the need for using under special meteorological conditions.
• It’s environmental machine, which complies with environmental requirements relevant laws and regulations;
• Both main and auxiliary legs can be dismantled so as to transport conveniently and save cost on shipping.
• The crane truss can adopt ground control or cab control.

Double girder truss gantry crane

Double girder crane truss has two truss main beams and its trolley usually travel along the track on the top of the beams, and the crane truss travels along its track on the ground. When the double girder gantry crane has cantilever, there should be saddle equipped with the crane; if there is no cantilever, there is no need to set the saddle on the crane truss.YFjHenan Weihua Machinery Co., Ltd
