150 Ton Trussed Type Bridge Launcher Girder Crane for Road Construction
Product Description
150 Ton Trussed Type Bridge Launcher Girder Crane is used for erecting concrete box girders for high speed (250km, 350km) passenger railway lines. This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m, 50m. The rear part has two supports. One of the supports is "C" shape column with rotary and foldable technology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.

Maintenance
Mainly check the main beam, check every ten days. Check whether there are cracks in the welding seam of the connection, whether there is residual deformation and instability of the main beam. If problems are found, stop using them and repair them.
1. The steel wire rope should be lubricated regularly every two weeks, and the dirt should be removed before lubrication.
2. If you find any twists on the wire rope and find that there are more than 6 broken wires, you should immediately scrap it and update it. (Check before class every day)
3. When the wheel wear exceeds 15% of the original thickness or there is cracking, it should be renewed.
4. There must be no shortage of oil in the reducer, it should be replaced regularly, and any abnormality and noise should be found for timely maintenance.
5. The brake of the lifting mechanism should be checked once before each use, and the brake of the running mechanism should be checked before each use every day.
6. The auxiliary hoist uses electric hoist. Due to improper operation during use, parts loosen, metal fatigue and other reasons occur. Special emphasis is placed on checking once a week and careful recording.
1. The professional electrician of the Bridge Launcher Girder Crane manufacturer is responsible for this work, and fill in the electrician maintenance record.
2. Keep electrical equipment clean, such as resistors, control screens, contactors, etc. Remove internal dust and dirt to prevent leakage, short circuit and other shortcomings. Check by the electrician every day and fill in the duty records.
3. Often observe the motor rotor slip line, brushes are in good contact.
4. Whether the sound from the motor, electromagnet, circuit breaker, electromagnetic switch, etc. is normal.
5. When the use conditions are bad, the insulation resistance of the motor and wire should be measured regularly. Attention of Bridge Launcher Girder Crane manufacturers: conductive slide wire, support insulation and grounding of various shells.
6. The rail clamp of the electric hoist and the connecting bolts of various components will loosen during the action, so each part must be carefully checked once a week.
