Lifting Equipment 100ton Double Girder Gantry Cranes With Electric Trolley
Product Description
Lifting Equipment 100ton Double Girder Gantry Cranes With Electric Trolley is actually a gantry crane, mainly used for outdoor yard, yard cargo, bulk cargo loading and unloading operations. Its metal structure resembles a portal frame, with two legs mounted under the load-bearing girder to walk directly on a track on the ground. Gantry crane has the characteristics of high site utilization rate, wide operation range, wide adaptability and strong versatility, and is widely used in the port yard.
Product Classification
Lifting Equipment 100ton Double Girder Gantry Cranes With Electric Trolley can be classified according to the door frame structure form, according to the main beam form, according to the main beam structure, according to the use form.
1. According to the frame structure is divided into gantry crane and cantilever gantry crane;
2. According to the main beam form, it is divided into single main beam and double main beam;
3. According to the main beam structure, it is divided into truss beam, box beam and honeycomb beam.
4. According to the use of gantry cranes, hydropower gantry cranes, shipbuilding gantry cranes, gantry container cranes.
Product Maintenance
- Maintenance of metal structure
The main thing is to check the girder, every ten days. Check the connection weld for open weld cracks, and the main girder for residual deformation and instability.
- Repair and maintenance of main parts
1. The wire rope should be lubricated regularly once every two weeks, and dirt should be removed before lubrication.
2. If any twist of the steel wire rope is found and more than 6 pieces are found broken, it shall be scrapped and updated immediately. (daily pre-shift inspection)
3. When the wheel wear more than 15% of the original thickness or crack, should be updated.
4. The reducer can not be short of oil, should be regularly replaced, found abnormal and noise timely maintenance.
5. The lifting mechanism of the brake before each use first check, the running mechanism of the brake check once a day before use.
6. The auxiliary lifting adopts electric hoist, which causes loose parts and metal fatigue due to improper operation. Special emphasis is placed on weekly inspection and careful recording.
- Maintenance of electrical equipment
1. This work shall be completed by the professional electrician of the gantry crane manufacturer, and the electrician maintenance record shall be filled in.
2. Keep the electrical equipment clean, such as resistor, control screen, contactor, etc. Remove internal dust and dirt to prevent the occurrence of bad phenomena such as electricity leakage, breakdown and short circuit. Check by electrician everyday, fill in duty record.
3. Often observe whether the motor rotor sliding line, brush contact is good.
4. Whether the sound emitted by motors, electromagnets, power breakers and electromagnetic switches is normal or not.
5. When the operating conditions are bad, the insulation resistance of motors and wires should be measured regularly. Attention of gantry crane manufacturer: conductive slide wire, bracket insulation and various housing grounding.
6. The electric hoist rail clamp and all parts of the connection bolts in action will be loose, so every week to each part must be carefully checked.
