Gantry crane specifications and crane parts and components

 Why to buy gantry crane? What is the advantages of gantry cranes? To buy gantry crane with low gantry crane cost is available for Dongqi Hoist and Crane. Check advantages to buy gantry crane from Dongqi crane manufacturer.

As the economy continues to struggle, companies are reluctant to make large investments, especially in the material handling industry. Large permanent lifting solutions are costly, so companies are looking to solve their material lifting needs without making large investments. Gantry cranes are a great alternative to large, permanent systems because gantry cranes offer up to a 15 ton lifting capacity and are completely mobile.

  • Gantry cranes with the runway located on the floor can be used where the overhead crane or bridge is not practical.
  • Gantry cranes are more cost-effective comparing with the overhead crane system.
  • Gantry cranes have a wide application. Gantry can be used indoors and outdoors. Gantry cranes can be used when the existing factory structure which cannot bear the wheel loads of the overhead crane; or loads needs to be handled outside the crane span and when the relocation of the crane is required after the work at a certain site is completed.
  • Quick assembly with bolt-together components. All types of gantry crane components are available.
  • Gantry crane is versatile. Gantry crane be easily customized to your application.
  • Available power drive kits.
  • Gantry cranes can be used indoors or outdoors in steel or aluminum with adjustable heights, spans, or treads. With adjustable heights, spans, and treads allow loads to fit easily through doorways or around obstacles during transportation.

To buy a gantry crane can simply be rolled into an employee’s workstation and be lifting in seconds. If the gantry will always follow the same path, fixed-path gantry cranes make moving the gantry crane simple and fast. If space is an issue, a single leg gantry crane can provide a lifting solution using a wall-mounted I-beam and a single A-frame leg. Different wheel options allow the gantry crane to have the right wheels for specific applications.
Power drive kits further is a compliment to the versatility of gantry cranes.

How to buy gantry crane

Considerations on buying gantry crane

When considering to buy gantry crane, the following things should be taken into consideration:

  • When buy gantry crane, the first is overall consideration of the industrial gantry crane use scope, working frequency, utilization, rated lifting capacity, traveling span, lifting height and other factors.
  • After working out the gantry crane buying plan, the crane buyers have to confirm the baisic information of the gantry crane with  the gantry crane manufacturer and supplier, such as what is the gantry crane lifting height? What’s the maximum lifting capacity? What’s the longest traveling distance? How is the gantry crane operation environment? And the gantry crane working frequency (working hours)?
  • After know about the above technical parameters of the needed gantry crane, Dongqi Cranes will provide gantry crane purchaser with good and suitable gantry crane solution apply to the lifting requirement.

Gantry Crane terms on buying gantry crane

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.

  • 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,.
  • Gantry crane lifting height: It is the distance between spreader upper limit position and lower limit position.
  • Crane Span:It means distance between the wheel vertical centerline at both sides of the crane.
  • 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.
(2) Gantry crane traveling speed: it is the crane traveling speed when crane traveling mechanism motor at rated speed.
(3) Gantry crane 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, 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).
  • 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 supply

The supplying of the gantry crane components and parts also plays a part in buying gantry crane. 

1. Gantry crane mechanical parts: Including three mechanisms namely the lifting mechanism, trolley traveling mechanism and gantry crane traveling mechanism.

  • 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.

2. Gantry crane metal structure part: It is mostly consisted of gantry frame and trolley.
3. Gantry crane electrical parts: It consists of the electrical equipment and electrical lines.

Gantry crane parts

  • 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.
  • Gantry crane traveling mechanism: It consists of crane motor, brake, reducer, coupling, transmission shaft, angle bearing box, wheels and other component parts.
  • Lifting trolley: consists of trolley frame, lifting mechanism and trolley traveling mechanism.
  • 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.
  • 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.
