Concrete pump boom long 37-45m

The concrete pump boom truck was modified on the chassis of the truck, it equip power transmission, pumping and stirring device, cloth device and other auxiliary devices on the chassis. The power of the boom concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer box, and the hydraulic pump pushes the piston to drive the concrete pump to work. The concrete is then transported to a certain height and distance using the boom and the conveying pipe on the concrete pump truck. In addition to driving the pump truck, the engine of the small concrete pump truck is also used to drive the working device such as the pumping mechanism, the stirring mechanism and the distributing mechanism.



The displacement of the concrete pump truck depends on the number and diameter of the concrete cylinders, the reciprocating speed of the piston and the volumetric efficiency of the concrete cylinder suction. Check and keep the manual grease pump tank filled with grease before each pumping and after pumping. After pulling the grease tank, pull the handle of the grease pump and observe the agitated bearing and S tube clean grease can be spilled. During the work of boom concrete pump, the manual grease pump handle is pulled 10 times every 1 hour. The lubrication system of concrete pump trucks should be kept clean to prevent dust and other impurities from entering, and should not be in contact with acid and alkali substances. The system should be cleaned once every 500 hours. When the coating of the conveying cylinder (0.2-0.25mm) is not worn away and the concrete slurry or sand is present in the water tank at the rear of the piston, it indicates that the piston has been ground and the sealing body, the guiding ring and the dust ring of concrete pump boom need to be replaced immediately.
