Gantry cranes how to maintain and care

Gantry crane maintenance:
1. Lubrication
Crane agencies depend largely on the performance and life of lubrication.
Lubrication, maintenance of mechanical and electrical products, lubrication specification see its own, running carts, hoist girders vehicles should note once weekly grease. Fill hoist industrial gear oils (SY1172-80) 200, should regularly check the oil level, replenish.
Second, the wire rope
It should be noted the case of broken wire. When, if broken wire, broken or worn amount of shares to be scrapped, it should be replaced with new ropes.
Third, the spreader
Spreader must be checked periodically.
Fourth, the pulley block
Mainly the rope groove wears, whether the crack and pulley rim on the shaft or without jamming.
Five wheels
Regular inspection flange and tread, when part of the rim should be worn or cracked up to 10% of the thickness replace the new round.
When the tread surface of the two driving wheel diameter difference of more than D / 600, or tread surface appear serious injuries when the car light again.
Sixth, brake should be checked once per shift.
Brakes should be accurate action, not allowed to have a pin stuck phenomenon. Shoe should fit properly brake wheel, brake shoe clearance should be equal when loose.
Seven, gear oil spill causes and preventive measures
Common gear oil spill for three reasons:
1. The manufacturer unreasonable design: no special ventilation holes are too small holes or other design flaw can cause internal and external pressure reducer is not balanced and leakage fault in the design process, resulting in gear lubricant leakage malfunction. There may be cause gear head connection Mifengbuyan and other long-term use process caused leakage.
2. The level of processing technology resulting in limited contact surface casing and other precision is not enough, thus causing poor sealing performance and produce oil spills happen.
3. Due to the operator or improper maintenance maintenance personnel in daily use, resulting in internal blockage much internal pressure higher than the external pressure, but too much oil, fasteners not tightened so will result in the cabinet between the two The combination of surface oil spills caused by lax.
In order to effectively prevent oil leakage reducer, manufacturers should enhance the level of technology and design optimization: You can take in the filling hole cover plus a breather device is provided which can guarantee smooth internal and external pressure equalization. At the same time in the design process should improve the housing bond between two surface craft precision, since the contact surface to prevent oil spills caused by lax failure. While in daily use has to do maintenance work on the vent, fuel, housing, fasteners and other periodic checks whether it is a conventional state.
