Generally speaking, in the same construction site are not, and should not be carried out for several consecutive days without stopping to use, it is necessary to retain sufficient time to strengthen the maintenance of the boom pump truck. Let Xiaosha introduce you to a few boom pump truck maintenance tips.

(1) boom pump pumping part of the maintenance, such as boom pumps work every 8 hours to check the oil quality and oil level of the hydraulic oil, if necessary, supplement and replacement, the new addition of hydraulic oil must be the same as the oil tank in the oil grade, boom pumps factory-filled hydraulic oil for Esso H46.
General pumping 20,000 cubic metres of commercial concrete or use half a year should be a thorough replacement of oil, oil change must be cleaned oil tank, and the parts of the cylinder for oil treatment.
(2) Boom pump truck work every 8 hours to check the oil level of the lubricant, boom pump truck pumping part of the maintenance recommendations for the use of 00 # non-extreme pressure type semi-fluid lithium grease, in the pumping of the concrete cylinder connected to the water tank, the size of the S-pipe bearing seat and the mixing end of the seat should be lubricant overflow.
(3) After pumping 3,000 square metres, the boom pump should adjust the gap between the spectacle plate and cutting ring, and replace them immediately if they are seriously worn out. Check the commercial concrete live should be sealed well, no mortar seepage into the tank.
(4) boom pump truck should check the S tube and S tube bearing position wear condition after 500 hours of use, boom pump truck pumping part of the maintenance if necessary to replace the bushing and taper sleeve.
(5) Check the suction filter vacuum gauge indication of the boom pumper, such as the position of the vacuum gauge pointer reaches the red area (i.e. more than 0.04Mpa) must be replaced filter element.
(6) At the time of switching on the pump, each system must be checked to see if the system pressure is normal, and check if the hydraulic system is leaking.

(1) The gear oil in the rotary reducer of the rotary table must be replaced in its entirety after the first 100 hours of use of the boom pump truck, and each subsequent oil change should be carried out at intervals of 1,000 hours (or half a year), and the recommended grade for the maintenance of the boom truck's upper arm is South China Sea 85W-90 heavy-duty gear oil, with a filling volume of 8 litres.
(2)The lubrication at each articulation of the boom and outrigger, slewing large gear ring bearing and the oil nozzle at the shaft end of the slewing reduction gear should be inspected and oiled every 60 working hours, and the lubricating grease used should be 3# calcium-based grease.
(3) Boom pump truck boom top mounted maintenance In order to reduce the danger and failure when pumping commercial concrete, it is necessary to use the correct pipe diameter and thickness of the conveyor pipe, the correct pipe clamps, and safety locks.
(4)Boom Pump Truck Boom Upholstery MaintenanceIn order to make the wear and tear even and make the life of the conveying pipe longer, you can rotate the conveying pipe regularly: for every pouring of about 5000 squares, the straight pipe is turned clockwise by 120 degrees, and the curved pipe is turned by 180 degrees.
(5)Boom pump truck should carefully check the welds of the slewing table, boom and outriggers at various places after working for a period of time, if there is any weld cracking phenomenon, you should contact our company immediately for proper treatment.
(6)The whole boom pump should be cleaned after the pumping of commercial concrete is completed, and the residual commercial concrete in the conveying pipe is strictly prohibited.
(7) Boom pump truck boom mounted maintenance to ensure the safety of the equipment, boom pump truck is only allowed to connect the front end of the 4-metre hose, not allowed to add any other pipeline.

(1) commercial concrete boom pump chassis maintenance such as the first use of 50 hours after the oil should be replaced, while replacing the oil filter and diesel fine filter, and cleaning the diesel oil filter and air filter. Subsequently replaced every 250 hours.
(2) commercial concrete boom pump chassis maintenance, such as the usual oil level is insufficient to add, you must use the same grade and type of oil to meet the requirements.
(3) Commercial concrete boom pump chassis maintenance, every 10 hours or once a day to check the oil level, such as the amount should be injected in time.
(4) Maintenance of commercial concrete boom pump truck chassis, the gear oil of the power take-off splitter box should be replaced after 200 hours of use, and each subsequent oil change should be carried out at an interval of 1000 hours (or half a year), and the grease in the bearing of the power take-off splitter box should be refilled once every 1000 hours.
