NLH series hoist double girder bridge crane Product advantages 1.NLH series hoist double girder overhead cranes and general crane height reduced by about 50% compared to the machine, 10 tons double girder bridge crane, wheel pressure reduced by about 30%, qd type double girder bridge crane, weight is reduced by about 35 percent, greatly reducing the construction cost of the plant user. 2. Ordinary hoist double girder crane working-level can only reach A3, A4, Bozhou double girder bridge crane, not suitable for heavy or heavy materials handling conditions. NLH series of electric hoist double girder crane working level to achieve A5, A6 or even higher. 3. hook limit smaller, bigger operating area. 4. Lifting the drive motor and reduction gear box using imported products, hardened gears, long life and maintenance-free. 5. Adopts triple gear, wheel mounting position with the overall boring processing technology, the wheel mounting high-precision, completely solve the skew problem. 6. The crane can be equipped with advanced safety monitoring system (crane "black box"). 7. towline car power supply with electrical conductivity, protect the cable, increase cable life. Bridge crane bridge crane classification can be divided into general overhead cranes, simple girder bridge crane and metallurgical dedicated bridge crane three. General overhead cranes generally consists of lifting trolley, bridge run institutions, bridge metal structures. Lifting the car and consists of hoisting mechanism, trolley traveling agencies and small frame three parts. Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer drive the drum rotation, so that the rope around the drum or the roll down to lift weights. Small holder and mounting frame is lifting mechanism and trolley traveling agencies and other parts of the frame, usually welded structure. Drive mode crane operating agencies can be divided into two categories: one for the central drive, which uses an electric motor to drive the long drive shaft on both sides of Active Wheel; the other for each drive that active on both sides of each wheel with a single a motor drive. Medium and small more using a combination of overhead crane brakes, gear units and motors into one of the "triple play" drive mode, the large overhead crane lifting capacity of the ordinary for ease of installation and adjustment, the driving device often used universal coupling .
