Truss gantry crane

Truss crane overview

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.IIGHenan Dongqi 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.IIGHenan Dongqi 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.IIGHenan Dongqi 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:IIGHenan Dongqi 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.IIGHenan Dongqi 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.IIGHenan Dongqi 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.IIGHenan Dongqi 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).IIGHenan Dongqi Machinery Co., Ltd

Wheel load

The maximum vertical pressure that trolley weight and rated weight function on the crane traveling wheels, when gantry frame weight and trolley are in extreme position.IIGHenan Dongqi Machinery Co., Ltd
