20t (Europe) Style Electric Double Girder Overhead Bridge Crane for Qd/Lh Type

20t wireless remote control European(Europe) Style electric double Girder Overhead Bridge Crane for QD/LH type

Henan Eternal Win is mainly engaged in all kinds of cranes ,such as single girder overhead crane ,double girder overhead crane ,single girder gantry crane ,double girder gantry crane ,jib crane ,port crane ,hydraulic crane , its accessories, hoist ,winch ,rail and so on .It is the remember unit of China Quantity Inspection Association and also the vice-chairman unit of China Heavy Machinery Industry Association.

Double girder electric overhead crane has the advantages of compact shape dimension, low building headroom height, light weight,small wheel pressure and so on. It uses together with CD1 or MD1 electric hoist. It is suitable for transporting, assembling ,repairing and load; unload works in mechanical processing workshop,metallurgy auxiliary workshop, storage, yards, power station and so on. It can replace normal double-beam bridge crane and being used in workshop of textile industry and food industry. The work type can be divided into two kinds- light class and intermediate class, the temperature of working environment is -25ºC-40ºC,

The European type overhead crane is designed based on international standard: FEM (Europe), DIN (Germany), ISO(International), equipped with many advantages such as: strong rigidity, light dead weight, low power, outstanding structure design etc. 

The configurations are very advanced, such as Sch neider electrics, ABM/Nord / SEW triple gear motor (three in one: motor, gear box, brake), galvanized high strength wire rope, self-adjusted disk brake, hard tooth reducer, programmable lifting limit switch, and so on.

Overhead crane (Bridge Crane, EOT crane) is composed of bridge, travelling mechanisms, trolley, electric equipment. The bridge frame adopts box welded structure, the crane travelling mechanism adopts separate drive withe motor and speed reducer. 
It is characterized by more reasonable structure and higher strength steel as a whole.

LD Single Girder Overhead Crane is used together with CD1 model MD1 model electric hoist as a complete set.The single girder overhead crane is widely used in plants, warehouse, material stocks to lift goods.

LH Double Girder Overhead Crane is applied in open warehouse or rail sideways to conduct common loading unloading and material handling works. It is a heavy duty type overhead crane that satisfy frequenty using.

Main Features for European style overhead crane:

•  high reliability, safety, free maintenance rate;
      a) work duty: FEM2M, M5
      b) Protection class: IP55
      c) Insulation class: F 
      d) continuing rate: 60% ( for the high class motor)
      e) Cooling rate: 30% than normal crane
      f) Over temperature protection: 170ºC
  2.Compact design, small size, low self weight, low headroom
  3.low noise
  4.Power-saved. The total motor power is much lower than normal design.
  Main Girder:
  1. Main girder uses bias-rail box type structure, with optimized design and light dead weight. 
  2. Steel material. Q235B / Q345B.
  3. The cover and web plate should get surface rust removal by roller-way conveyor blasting machine before welding; this blasting machine can perform blanking, sandblasting, painting and drying.

• 4. The welding work of main girder should be performed on work platform (welding assembly unit). In order to avoid distortion of main beam, we adopts U-shaped welding assembly unit to assure that vertical deflection degree between the top cover plate and joint edge of stiffened plate and web plate is no more than H/200, and also effectively reduce the partial wave of web plate.
  
  End Carriage:
  1. Material use Q235B/ Q345B.
  2. It is made of rectangular steel-pipe or steel plate by welding, the finished end carriage get 1-time positioning process on numeral control machine in order to ensure dimension accuracy and fit tolerance.
  3. Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.
  
  Control:Pendent button control or radio remote control is on customer's request.

Safety Devices for overhead crane:

To guarantee the normal operation of crane and avoid the personal casualty and mechanical damage, the safety device we provide are not only the electric protective devices or alarm bell but also other equipments as following:

1.Overload Limit Switch

2.Rubber Buffers

3.Electric Protective Devices

4.Emergency Stop System

5.Voltage Lower Protection Function

6.Current Overload Protection System

7.Rail Anchoring

8.Lifting Height Limit Device
 

Advantages of a single girder overhead crane design:

• Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams

• Most economical option for light to medium-duty cranes

• Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.

• Better hook approach for both trolley travel and bridge travel

• Easier to install, service, and maintain

• Ideal for workshops, warehouses, material yards, and manufacturing and production facilities

• Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time

• Great for facilities with low headroom

Production workshop for double girder beam overhead crane


Advantages of Overhead Cranes are:

• Can be used where overhead runways are not practical.

• A much greater bridge weight than an equivalent overhead crane.

• Overhead Cranes are generally used for moving heavy loads,often outdoors.Eternalwin has designed and built many large gantries with features such as rotating hoists, multiple hoists and enclosed cabs.
