The gantry crane is a deformation of the bridge crane. Gantry cranes are suitable for use in yard and no corners in the factory. The form is divided into semi-gantry cranes and gantry cranes with a maximum tonnage of 300 tons. Apply to the port, yard, etc., to complete the outdoor freight yard, yard cargo, bulk cargo handling operations. Its metal structure like a door frame, carrying the main beam under the installation of two legs, you can walk directly on the ground track, the main beam at both ends can have extended cantilever beam.
Gantry crane work level A: It reflects the crane in the load state and the busy level, two aspects of the working characteristics.The division of the work level is determined by the utilization level U of the crane and the load state Q. They are divided into A1 ~ A8 eight levels. Crane working level,
That is, the metal structure of the work level, according to the hoisting mechanism to determine, divided into A1-A8 level, if the provisions of the crane with the type of work,Roughly equivalent to: A1-A4- light; A5-A6-; A7-heavy, A8-heavy weight.
Maintenance and servicing of Motorized Mobile Gantry Crane 5 ton 10 ton 15 ton 20 ton 25 ton
The performance and longevity of the various mechanisms of the gantry crane are largely dependent on lubrication.Lubrication, the maintenance of mechanical and electrical products, lubrication see their manual, travel carts, heavy truss, etc. should be a weekly grease. Hoist filling industrial gear oil (SY1172-80) 200, should always check the oil level, timely added.
Should pay attention to wire rope broken wire situation. If broken wire, broken stock or wear to meet the retirement standards, should be replaced by new rope.
The spreader must be checked regularly.
Mainly check the rope groove wear and tear, whether the collapse of the rim and pulley in the shaft with or without jamming phenomenon.
Periodically check the rim and tread, replace the new wheel when the rim part is worn or cracked to a thickness of 10%.When the tread on the two main drive wheel diameter difference over D / 600, or tread on the occurrence of serious scars should be re-car light.
Each class should be checked once.
Brakes should be accurate, the pin is not allowed to jam phenomenon. Brake shoes should be properly fit brake wheel, brake clearance when the gap should be equal
Seven, reducer leakage causes and preventive measures
Common reducer leaks for three reasons:
1: As the manufacturer's design is unreasonable: in the design process without special ventilation holes or ventilation holes are too small design defects will cause uneven reducer internal and external pressure leakage and failure, eventually leading to reducer lubricants leak malfunction. There may be in the long-term use of the reducer caused by the connection surface seal is not strict cause leakage.
2. The limited level of processing technology caused by the contact surface of the box and other precision is not enough, resulting in poor sealing performance and oil spill occurred.
3. As the operator or maintenance personnel in the daily use of the maintenance process inappropriate, resulting in internal congestion and internal pressure above the external pressure, while excessive oil, fasteners are not tightened, etc. will cause between the two boxes Of the joint surface is not strict caused by oil spill.
