European standard overhead crane for Bangladesh textile industry customer

6 ton and 10 ton European standard single girder overhead crane for Bangladesh textile industry customer. European standard single girder overhead crane small dimension and light dead weight. European cranes are suitable for long hours of high frequency operation.

European standard single girder overhead crane

European standard single girder overhead crane is a kind of lifting equipment which is used in workshop, warehouse and yard to lift the materials or loads. It has such design concepts as small dimension, light dead weight. Compared with traditional cranes, the limiting distance is smaller from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height is much higher, which increases effective working space of workplace. New workshops can be designed smaller and have more functions, because the dead weight is very light and the wheel pressure is small. Smaller size workplace means saving a huge amount of money from initial construction investment, long-term heating, air conditioning and other maintenance free.

European Crane Advantages and Structure Features

The concept of European cranes is formed in recent years in the industry, the purpose is distinguish from the previous so-called domestic, Soviet (Soviet), traditional cranes. Mainly include: overhead cranesgantry cranescantilever cranes, flexible beam cranes, explosion-proof cranes and other industrial cranes.

Europe machinery crane is a high-end type of crane, there is no this definition in technical concept. It is a summary of domestic crane (based on the Soviet design and manufacturing technology) reliable, versatile, low prices, combined with advanced Europe Crane advanced technology, compact structure, light weight, energy saving, low noise and other characteristics by Chinese end users.
It is a new definition of high-end bridge gantry crane according to the use of China's proposed characteristics of the bridge gantry crane. There is a clear market demand for this type crane.

Europe machinery cranes are based on the European lightweight and modular design concept and advanced manufacturing process, so that the entire crane compact, smooth operation, weight loss, height reduction, energy saving, greatly reducing the user's crane construction costs and crane Operating costs, improve the crane's overall quality and performance.

Advantages of European cranes

  • Reduce customer investment, make full use of plant space, improve production efficiency
  • Good combination, various specifications, product lines is complete, you can cover most of the needs of customers
  • Safe and reliable, advanced design concepts, mature technology to ensure product design
  • Advanced control technology and high quality key components ensure excellent crane performance
  • Reliable performance, low failure rate, lower use and post-maintenance costs
  • Intelligent equipment, set aside a variety of functional interfaces to make functional expansion easier

European Crane Main girder section


  • The main beam is designed with a box shaped Ankang h-shaped steel structure, which is similar to the traditional first simple driving type, and weighs more
  • Non-destructive inspection of the main welds
  • Steel plate materials use domestic general steel (Q235B)
  • Vertical winding is the national standard of China
  • As with traditional Chinese cranes, all steel plates are pretreated to achieve Sa2.5 standardization
  • Carefully inspect and clean the steel plate before welding, it usually by automatic welding (MIG or semi-automatic welding)

European Crane End Beam section


  • The end beam is welded and formed with rectangular steel tube or steel plate. After forming, the end beam is positioned at a time in the CNC machine tool to reach the allowable deviation range to ensure the national dimension precision and tolerance
  • Each end beam is equipped with double wheel rim of the wheel, the buffer and the derailment protection device
  • The double beam crane is in the direction of main beam driving side layout maintenance platform (maintenance walkway)
  • The main beam and the end beam are connected with high strength bolts to ensure the accuracy and smooth operation of the whole machine
Europe type cranes will become the mainstream of the development trend of cranes and market demand.

Once we get the above specifications, we talked with our designer engineer and conclude the technical & commercial offer for them.
Lifting capacity and lifting height are the normal specifications and no problem.The gauge is the rail to rail distance of the traveling trolley. As our standard double girder overhead crane is from 1.5meters to 2meters.After our discussion, we can customized the 1.1meters gauge for them.
We select the ABM Germany three-in-one motor and Schneider electrics for them. Three-in-one motor is the reducer motor which means motor, reducer and gearbox together as one. All electrics such as the contactor, inverter and switches are come from Schneider France.
Finally we satisfied all the questions for the Peoples’ Steel Mill, then we get the 5 ton electric crane trolley order.
Once we get the original irrevocable letter of credit from our customer, we start the production. Production last 25 working days. Below please take reference of some actual pictures.

About this kind European lifting mechanism, there is no any welding and all the connections are by the high strength bolts. All the motors are the variable speed motor and the shell box is stoving varnish technology.

Crane Cross Limit Switch Introduction

Most customers are curious to know what kind switches used for the hoist. We used are the below cross limit switch for the traveling. Cross limit switch is the cross shape. During the worktime, it can take two times protection for the crane traveling, the first stop will lower the traveling speed and the second stop will make the crane stop smoothly, in this way, we can reduce the damage which is taken by the collusion.

5 Ton European Type Electric Trolley Package and Delivery

After production, we send the client pictures for reference, then arrange the package.About the package, our company policy is package the hoist and electrics by wooden box. Once we load the box into the container, we will fix the box by rope again to avoid the damage from shipment collusion.
