Car routine maintenance crane crane technology
The concept car is the car and crane combination forms can not assemble themselves directly to work. Feature is convenient and flexible, high efficiency, fast transitions, improve work efficiency. Disadvantage is that the terrain, large equipment can not be completed. Mainly used in construction.
hoist equipment at normal operating circumstances, at regular intervals (about a year) for a major overhaul or a period after the overhaul, replacement of worn bearings and other wearing parts, usually found the problem to any maintenance.
lift hoist in operation, always observe and inspect the brake, clutch, stopper role and wear, timely troubleshooting.
3 truck crane hoist long-term need, and then when you should be building a new installation of winches or overhaul inspection test methods, transportation maintenance construction hoist, should be stored in a dry place, the components should have good moisture, corrosion and other measures.
4 in the disassembly process, pay attention not to damage the mating surfaces, check friction surface wear, ministries gears, bearings, the various rotating parts, couplings and electrical components for wear, etc., such as the impact machines should be replaced.
hoist equipment hecking electrical equipment off before turning the power switch, electrical appliances must be kept clean, this must regularly remove dust, dirt, grease, etc., not allowed to have contact with oil, burning or oxidation of the contacts application of thin sandpaper, insulation rings are not allowed to wash with gasoline, in order to prevent the armature core contact surface rust, should be regularly lubricated with machine oil, then wipe clean cast iron resistors each section should be inspected regularly for cracks.
