Why choose QDX European double girder bridge machine ?

QDX European Double-girder bridge crane is exquisitely designed and well-made, and its hoisting mechanism is light in weight, small in size, low in height, and stable in performance; it has the advantages of low cost, light weight, stable operation, and maintenance-free. Better Reduce infrastructure costs.

Product advantages and features of QDX European double girder bridge machine

• Well-designed Well-made The quality of the main beam determines the life and cost of the crane. “Sino Lifting” skillfully uses the most advanced main beam design and processing technology in Europe.
• The staple food has a long-lasting quality, which not only allows users to use it with confidence, but also reduces users’ maintenance costs.
• The upper camber curve of the main girder adopts an optimized quadratic curve to ensure that the running mechanism runs without uphill resistance under full load conditions, thereby overcoming the shortcomings of the overload operation of the running motor and the trolley running on the slope.
• The end beam is a box beam, and the middle of the end beam and the main beam is connected by high-strength bolts, which is convenient for transportation.
• The optimized structure design makes the bearing layout reasonable, can bear the horizontal force, and improve the service life of the bearing. The mechanical parts are connected by gears, which is easy to install and easy to maintain.
• In addition, the active and passive train wheels are supported on the crescent-shaped bearing box, which is convenient for disassembly and adjustment.

The difference between European Double girder overhead crane and ordinary cranes

Because the trolley of an ordinary crane is so large, the size of the bridge frame of the whole crane is required to be very large. Under the same working level, the weight of the whole machine is very different.

1. European overhead crane adopts crescent wheel, and generally adopts angular bearing box wheel Ordinary hoist double-girder cranes use angular bearing box-type wheels, and the installation accuracy is adjusted by hand. During operation, the phenomenon of rail gnawing is easy to occur; European-style hoist cranes use crescent-shaped wheels, and the end beams are made of boring holes. The installation method Simple, the accuracy of the machine tool is used to ensure the installation accuracy, which is more reliable, and the phenomenon of rail gnawing is not easy to occur.
2. The European-style overhead crane work level is high, and the ordinary work level is low.  The traditional MD1 type fixed hoist used by ordinary hoist double-girder cranes can only achieve A3 maximum working level, while the European hoist is designed with foreign advanced technology, and its working level can reach A5.
3. European double girder overhead crane has low noise, and ordinary noise is high.  The noise of the traditional MD1 type fixed hoist reaches 85db, and the maximum noise of the European hoist is only 70~75db.
4. The European hoist gear adopts hard tooth surface, and the ordinary hoist gear adopts medium hard tooth surface. In the traditional MD1 type fixed hoist, in the production process, the gears are processed with medium-hard tooth surfaces, which have low bearing capacity and low working level. The European hoist is designed with foreign advanced technology, the gear is designed with hard tooth surface, and the working level is A5.
5. The European-style hoist gear adopts frequency conversion design, and the ordinary hoist gear adopts two-speed design The traditional MD1 type fixed hoist is driven by the sub-motor, the shaft of the small motor is easily broken, and the large ring gear is easily damaged. The European-style hoist adopts the frequency conversion motor design, the output torque is stable, and the buffering is small.
6. European three-in-one drive, ordinary motor + reducer + brake.  The trolley operation of the common crane adopts the structure of motor + reducer + brake, which widens the size of the entire walking platform and increases the weight. The failure rate is high. The operating mechanism of the European crane adopts a three-in-one drive, which is small and precise. The quality of the product can be easily guaranteed.
7. The European-style bridge crane cart has a small track, and the ordinary cart has a large track. Because the whole machine of ordinary cranes is heavier, and the maximum wheel pressure is larger, heavier rail models must be used. The whole machine of European bridge crane is light, the maximum wheel pressure is small, and lighter steel rails can be used.
8. The power of the European-style bridge crane is small, and the power of the ordinary machine is large. At the same working speed, the dead weight of the ordinary bridge crane is high, and the power of the whole machine is also large, while the dead weight of the European crane is small, and the power of the whole machine is also small.
9. The limit size of the distance between the two hooks of the European style is small, and the limit size of the distance between the two common hooks is large. Due to the large size of the trolley of the ordinary hoist double-girder crane, the distance between the two lifting points must be increased. The size of the European hoist trolley is small, and the distance between the hooks is small.
10. The size of the European end beam is small, and the size of the ordinary end beam is large Because the ordinary hoist double-girder crane adopts the angular bearing box structure, the size of the end beam must be large. The European-style hoist crane adopts crescent-shaped wheels, and the size of the end beam is small, which can save the structural size of the workshop.
11. The European lifting limit adopts the cam limit, and the ordinary lifting adopts the traditional fire limit. The precision of the cam limit is high, and there is no potential safety hazard. The traditional fire limit is a collision limit. If the fire fails, there is a great safety hazard.
