Generally speaking, in the same construction site will not, and should not be used for several consecutive days without stopping. Sufficient time must be reserved to strengthen the maintenance of the boom pump truck. Let Xiao Sa introduce you to some tips for the maintenance of boom pump truck.

(1) Maintenance of the pumping part of the boom pump truck. For example, check the oil quality and oil level of the hydraulic oil every 8 hours when the boom pump truck is working, and supplement and replace it if necessary. The newly added hydraulic oil must be consistent with the oil brand number in the oil tank. The hydraulic oil filled in the boom pump truck is Esso H46 when leaving the factory.
Generally, 20000 cubic meters of commercial concrete should be pumped or used for half a year, and the oil should be completely replaced. When changing the oil, the oil tank must be cleaned and the oil cylinder in each part should be drained.
(2) Check the oil level of lubricating oil every 8 hours when the boom pump truck is working. It is recommended to use 00# non-extreme pressure semi-fluid lithium base grease for the pumping part of the boom pump truck. During pumping, lubricating oil should overflow at the places where the concrete cylinder is connected to the water tank, the S-tube size bearing seat and the stirring end seat.
(3) boom pump truck in the pumping 3000 should be adjusted after the gap between the glasses plate and the cutting ring, such as serious wear and tear must be replaced immediately. Check that the commercial concrete shall be well sealed and no mortar shall penetrate into the water tank.
(4) boom type pump truck in the use of 500 hours should check the S tube and S tube bearing position wear condition, boom type pump truck pumping part maintenance when necessary to replace the shaft sleeve and taper sleeve.
(5) Check the vacuum gauge indication of the suction filter of the boom pump truck. If the position of the vacuum gauge pointer reaches the red area (that is, more than 0.04Mpa), the filter element must be replaced.
(6) When starting up, each system must be checked to see if the system pressure is normal and check whether the hydraulic system is leaking.

(1) The gear oil in the rotary reducer of the turntable shall be completely replaced after 100 hours of first use of the boom pump truck, and each subsequent oil change shall be carried out at intervals of 1000 hours (or half a year). The brand recommended for maintenance on the boom of the boom pump truck is Nanhai 85W-90 heavy gear load oil with a filling amount of 8 litres.
(2) The lubrication of the arm frame, each hinge of the outrigger, the bearing of the large rotary gear ring and the grease nipple at the shaft end of the rotary reduction gear shall be checked and oiled every 60 working hours. The lubricating grease used is 3# calcium-based grease.
(3) Boom-type pump truck boom installation and 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 delivery pipe, the correct pipe clip and safety lock.
(4) The boom of the boom pump truck is installed and maintained. In order to make the wear uniform and the service life of the conveying pipe longer, the conveying pipe can be rotated regularly: for every pouring of about 5000 square meters, the straight pipe turns 120 degrees clockwise and the elbow turns 180 degrees.
(5) The boom-type pump truck shall carefully check the welds of the rotary table, boom and outrigger after working for a period of time. If the welds crack, contact our company immediately for proper handling.
(6) After the work of pumping commercial concrete is completed, the entire boom pump truck shall be cleaned, and it is strictly prohibited to leave commercial concrete in the conveying pipe.
(7) The boom of the boom pump truck is installed and maintained. In order to ensure the safety of the equipment, the front end of the boom pump truck is only allowed to connect 4 meters of hose, and no other pipes are allowed.

(1) Commercial concrete boom pump truck chassis maintenance. If it is used for the first time for 50 hours, the oil should be replaced, the oil filter and diesel fine filter should be replaced at the same time, and the diesel coarse filter and air filter should be cleaned. Replace it every 250 hours.
(2) Commercial concrete boom pump truck chassis maintenance, such as the usual oil level is insufficient to add, must use the same brand and model of oil to meet the requirements.
(3) commercial concrete boom type pump chassis maintenance, every 10 hours or every day to check the oil level, such as the amount should be injected in a timely manner.
(4) The chassis of the commercial concrete boom pump truck shall be maintained. The gear oil of the power take-off transfer case shall be replaced after 200 hours of use. Each subsequent oil change shall be carried out at intervals of 1000 hours (or half a year). The butter in the power take-off transfer case bearing shall be filled every 1000 hours.
