L48A1 Mast Section Lubrication characteristics and key parts of lifting machinery
Lifting machinery refers to lifting or lifting heavy objects and materials handling, transporting, loading and unloading materials on a certain line, such as: tower cranes, cranes, elevators, hoists, conveyors, hoists, handling and loading vehicles, etc.. Now we say, lifting machinery lubrication characteristics:
1 Due to the wide range of use of lifting machinery, the environment and working conditions are different, including indoor or open-air environment, room temperature and high temperature environment. Therefore, there are often great differences in the selection of lubrication materials, lubrication methods, and replacement replenishment cycles. Therefore, for two identical devices, different lubrication materials are often selected due to different operating conditions. Some medium-and small-tonnage bridge and door cranes often use decentralized lubrication. Some rolling bearings and sliding bearings that are not easy to fill are often lubricated by centralized grease, and some large crane reducers are commonly used for centralized oil supply systems. Including oil bath lubrication or oil supply from oil pumps.
2 Lubricating materials used in lifting machinery usually require water resistance, high temperature, low temperature resistance, and anti-rust and anti-extreme pressure characteristics.
The selection of lubrication materials must follow the instructions and relevant data, and combine the actual conditions of use of lifting machinery for comprehensive consideration.
The lubrication materials of different parts of lifting equipment are quite different. Therefore, must not mix, otherwise will cause equipment accident, leading to parts damage.
The key parts of lubrication of lifting machinery are roughly distributed as follows:
1 thrust bearings at both ends of the hook pulley shaft and under the hook nut.
2 Fixed two ends of pulley shaft(on cart stand).
3 wire rope.
4 Each speed reducer(a vertical speed reducer with a large center, and a single lubrication point at the high-speed first and second bearings).
5 Each gear coupling.
6 Each bearing box(including wheel group angular bearing box).
7 motor bearings.
Each hinge on the 8 brake.
The piston part of the 9-stroke brake electromagnet(MZSI type).
10 roller.
11 Cable reel, cable trailer.
12 Grab the upper and lower pulley oil and guide the roller.
Gears, rods and joints on 13 clamps.
