Routine maintenance of aluminum mast lift
1 product activation should be replaced after six months of hydraulic oil, after making use of the frequency and extent of contamination of hydraulic oil for occasional replacement. Replacing the hydraulic oil should thoroughly clean the tank wall, can not let the metal particls, cotton yarn, fiber and other foreign matter into the tank.
2 must strictly prevent contamination of the hydraulic fluid, without water, acid, alkali and other impurities in the oil, the fuel tank may not oiled.
3. Use should always check the tightness of the lifting arm drive chain group, if the situation is obviously not flush found between the upper end of the lifting arm when not raised, or when the process up the chain tension is inconsistent with the group since the chain should adjust length. Raised from the platform when adjusting a height to be adjusted to look for screwing the lower end of the arm section of the nut (M8 × 1), while adjusting the edge inspection, until it meets the requirements
(4) If the solenoid valve due to the occurrence of the phenomenon of foreign objects blocking the card, then remove the hydraulic system failure electromagnet, with 24MM socket wrench extension electromagnetic spool rotation, immersed in kerosene gently rotating spool, cleaning out which card live foreign body, then gently pull out the valve, check valve kit exhibits objects and injuries, post-processing, carefully loaded into the spool, the spool smoothly slide valve kit. Pay attention to maintaining the accuracy wife, then together into the valve body, and then loaded on to the electromagnet.
5 If you happen platform with automatic fall phenomenon, check jettisoning switch is loose, tighten clockwise case. If it is not a one-way check valve seal is reliable, or whether the check oil soft fiber resulting in a one-way valve failure, with 24MM socket wrench to unscrew the check valve, and if so, replace damaged seals seals, such as spool foreign body is diesel or kerosene to clean the spool, the spool will exclude foreign body Refit and tighten.
6 swap lift arm roller set or clear the foreign object after the installation of the roller set, the first platform to be raised to a certain height, the roller set to be swapped into the skid rail in the lift arm position, and the relative movable rail parts fixed platform using the roller group fall into the elevator arm, and then raised platform, installed lift arm end portion of the protector block, repeated several times up test, no abnormality, the exchange assembly work is completed.
7 non-professionals do not arbitrarily overhaul hydraulic system components. If unsure, do not self-study, could be entrusted to the factory for repair.
8 aerial lift platform should be kept clean. When not in use, should be parked in the rain, sun, dry and ventilated place.
9 aerial lift platform requires lubrication, maintenance parts should always raise N32 machine oil: chain sprocket friction parts; sprocket, chain wheel friction parts; lift arm roller friction parts; under the chassis casters, directional wheel rotating parts .
