20t Single Girder Overhead Crane(Standard clearance hoist)

描述

20t Single Girder Overhead Crane(Standard clearance hoist) Description:

The single girder overhead crane is based on the European lightweight and modular design concept and advanced production and manufacturing technology. It suspends the electric hoist lifting mechanism on the main girder, which can realize the three-dimensional movement of materials and objects in the space. The product is technologically advanced and designed according to international standards: DIN (Germany), FEM (Europe), ISO (International), with advantages of strong rigidity, light weight, outstanding structural design, etc. It can effectively save factory space and investment costs. The unique walking structure is your best choice.

The single girder overhead crane has a lifting capacity from 1 ton to 20 tons, and the span can reach 28.5 meters. It is an ideal choice for industrial applications and is very popular in the market. It has superior performance, compact structure, light weight, green and energy-saving, quiet, low wheel pressure, safe and reliable, and high energy operation, which can help you effectively utilize available space, save the overall investment cost of the plant, improve production efficiency, reduce daily maintenance, and save operational energy consumption, achieving better investment returns.

  1. Designed according to FEM and GB3811 standards.
  2. The series product is used in conjunction with European-style electric hoist.
  3. The main girder is a box girder with computer optimization design and steel structure finite element optimization design, with light weight.
  4. The end beam is an anti-twist box type, realizing modular design, with light weight and small volume.
  5. The wire rope electric hoist has a small height dimension, allowing the hook to be closer to the edge, increasing the service working area.
  6. Provide high-flexibility flat cable power supply for the trolley, with grounding protection.
