Gantry Crane Specification
To buy a gantry crane, you have to learn the gantry crane specifications, such as, lifting capacity, lifting height, span, mechanism operating speed, working class, gantry crane total weight and wheel load.s0RHenan Dongqi Machinery Co., Ltd
1. Gantry crane lifting capacity: It referes to the maximum allowable lifting capacityunder normal work conditions. Dongqi gantry crane max. lifting capacity is up to 1,000 ton,.
2. Gantry crane lifting height: It is the distance between spreader upper limit position and lower limit position.
3. Crane Span:It means distance between the wheel vertical centerline at both sides of the crane.
4. Gantry crane each mechanism operating speed
(1) Gantry crane lifting speed: it is the extract device full loaded lifting speed when lifting mechanism motor at rated speed.s0RHenan Dongqi Machinery Co., Ltd
(2) Gantry crane traveling speed: it is the crane traveling speed when crane traveling mechanism motor at rated speed.s0RHenan Dongqi Machinery Co., Ltd
(3) Gantry crane trolley traveling speed: it trolley traveling speed when the trolley traveling mechanism motor at rated speed.s0RHenan Dongqi Machinery Co., Ltd
5. Working class: Indicators of the whole crane lifting full load level and lifting numbers degree, working class divided into A1-A8 total of eight levels, light duty (A1-A3), intermediate duty (A4, A5), heavy duty (A6, A7), extra heavy duty (A8).
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.
Gantry crane components and parts
1. Gantry crane mechanical parts: Including three mechanisms namely the lifting mechanism, trolley traveling mechanism and gantry crane traveling mechanism.s0RHenan Dongqi Machinery Co., Ltd
Hoisting mechanism of the gantyr crane is used for vertically lifting,
Trolley traveling mechanism is used for laterally move with loads;
Crane traveling mechanism used for the lifting trolley and the items longitudinal move, in order to achieve handling, loading and unloading in a three-dimensional space.
With those travelling machannism, gantry crane can efficiencty transfer and lift your loads.s0RHenan Dongqi Machinery Co., Ltd
2. Gantry crane metal structure part: It is mostly consisted of gantry frame and trolley.s0RHenan Dongqi Machinery Co., Ltd
3. Gantry crane electrical parts: It consists of the electrical equipment and electrical lines.s0RHenan Dongqi Machinery Co., Ltd
Gantry crane parts
1. Gantry crane gantry frame: It consists of two main beams, two end beams, walkway, railings, supporting legs and other component parts. Its structure including two: box type gantry crane and truss type gantry crane.
2. Gantry crane traveling mechanism: It consists of crane motor, brake, reducer, coupling, transmission shaft, angle bearing box, wheels and other component parts.
3. Lifting trolley: consists of trolley frame, lifting mechanism and trolley traveling mechanism.
4. Gantry crane lifting mechanism: consists of motor, brake, drive shaft, coupling, reducer, drum, fixed pulley block, wire rope and other component parts. Include single brake and double brake.
5. Gantry crane driver’s cabin: the crane operator’s work place. Inside equipped with control device (linkage or cam controller), power protection box, signal equipment and lighting device. Only after the cabin door closed, the crane can start (limit protection). This prevents causing injury when crane start traveling while there was someone working on the crane or operator have not entered the cabin.
How to select gantry crane
1. Selection of gantry crane
Under normal conditions, the lifting capacity less than 50 ton, span less than 35m, no special use requirements, you can choose single girder gantry crane. If demands of large width between gantry legs, high operating speed, or often lifting heavy and long pieces object, you should choose double girder gantry crane.s0RHenan Dongqi Machinery Co., Ltd
2. Crane span and length of cantilever
Gantry crane span is an important factor affecting crane self-weight. During selection, under satisfy the crane operating conditions and under the premise of fit the specifications of span series, should try to reduce the span.s0RHenan Dongqi Machinery Co., Ltd
3. Judge criterion of wheelbase
(a) Meet the requires of security and stability along the gantry crane track direction;
(b) Dimension and shape of the object can realize smoothly through the supporting legs flat steel structure;
(c) Make the span S with the wheelbase B in a specific proportional relationship, usually take wheelbase B = (1 / 4-1 / 6) S.

4. Determine the distance scale of gantry crane
During operation, between gantry crane external, yard goods and transport vehicles channel, there should be left certain spatial scales, in order to facilitate loading and unloading operations. Usually delivery vehicles loading and unloading within the span, it should keep more than 0.7m distance with the gantry legs. When the crane spreader is not in operation, it should keep a distance of more than 0.5m with the delivery vehicles, when lifting object through gantry legs, there should be a distance of more than 0.5m.s0RHenan Dongqi Machinery Co., Ltd
5. Gantry Crane working environment
When select gantry crane, the working environment is also a decisive factor for gantry crane selection. The working environment includes climatic factor, rainproof factory, anti-corrosion factor, windy facotor Hanging piece volume factory, etc.s0RHenan Dongqi Machinery Co., Ltd
