With the increase of the construction machinery, all construction machinery are equipped with a crane lift equipment, so today the crane editor tell you how to do maintenance work tower crane equipment.
Safety Tips
a. professionals are not free removable appliances to prevent electric shock or incorrect connections.
b. lift work platforms below overhaul must Diaozhu support the work platform lifts, lifts to prevent a sudden drop in casualties.
c. shall be arbitrarily adjust the relief valve. Each hydraulic system components are working at a predetermined pressure. After any adjustment relief valve may cause abnormal operation of the hydraulic system. Human, machine, material, there will be unnecessary damage.
between any part of the d. the hydraulic system, you must first relief, in order to avoid pressure oil spray, table suddenly decline.
Monthly maintenance
a. wheel, intermediate shafts and bearings, cylinder pin and bearing, boom hinge shaft and bearings for wear.
b. all parts are filling some of the oil, extending bearing life.
c. oil and the oil level of the hydraulic oil. Lifts the whole rises when this position should be higher than the bottom surface of the hydraulic did 40-50 mm. Hydraulic oil is a dark, sticky or gritty and other foreign matter, if found, should be replaced (32 # hydraulic oil).
Year-end maintenance
a. Check all hydraulic lines and fittings. Not damaged pipes, fittings not loose, all joints must be tightened.
b. Remove and disassemble drop valve plunger blowing with compressed air, and then into re-placement.
c. The hydraulic oil exhausted discarded, remove the connector and tighten the oil filter after cleared, cleaned with compressed air, and then back into the tank and piping connection is good.
