Truss Type Single Girder Gantry Crane With Hoist

Truss type gantry crane main structure is truss structure, welded from shaped-steel, with light weight, small wheel pressure and reliable performance, evolved by Russian gantry crane; it is particularly suitable for large sandstorm place, generally for handling and lifting work. Generally include single girder truss gantry crane and double girder truss gantry crane.

Main specification including lifting capacity, lifting height, span, mechanism operating speed, working class, truss type gantry crane total weight and wheel load.
1. Truss type gantry crane lifting capacity: maximum allowable lifting weight during crane normal work. Commonly has 5ton to 100ton.
2. Truss type gantry crane lifting height: distance between spreader upper limit position and lower limit position.
3. Span: the distance between the wheel vertical centerline at both sides of the crane.
4. Truss type gantry crane each mechanism operating speed
(1) Truss type gantry crane lifting speed: it is the extract device full loaded lifting speed when lifting mechanism motor at rated speed.
(2) Truss type gantry crane traveling speed: it is the crane traveling speed when crane traveling mechanism motor at rated speed.
(3) Truss type gantry crane trolley traveling speed: it trolley traveling speed when the trolley traveling mechanism motor at rated speed.
5. 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).
6. 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.
