Chapter 2: Lifting Operations and Precautions for Dump Trailers for Sale

1. Operation sequence for lifting a dump trailer in Philippines: Open the tarpaulin or lid of the carriage - open the locking device - depress the clutch with the transmission in neutral and wait for 5 seconds - combine the power take-off - hang Low speed gear (below 4th gear) - put the air control valve handle in the raised position - release the clutch and the vehicle starts to lift. You can step on the engine accelerator appropriately but must control it within 1500 rpm - when the cylinder reaches the maximum stroke or the limit valve When dump trailer for sale in Philippines works, put the air control valve handle in the neutral position.

2. Vehicle descent operation sequence: Depress the clutch and wait for 5 seconds - Disengage the power take-off - Disengage the transmission gear - Release the clutch - Slowly turn the air control valve handle from the parking position to the descending position (Dayun The pneumatic control valve of the hydraulic lifting system of the rear-turning dump trailers for sale near me in Philippines is a proportional control valve, which can control the descending speed of the oil cylinder. The closer the handle is to the lowering position, the faster the cylinder descends) - wait 30 seconds after the car body is completely lowered to turn on the pneumatic control valve. The valve handle is in the neutral position.

3. Precautions for lifting the dump semi-trailer

The hydraulic cylinder of the rear dump trailer in Philippines is a special cylinder for lifting. The dump trailer for sale in Philippines is strictly prohibited to use the cylinder as a stable support for the body; the cylinder should not be left in the air for more than 2 hours in the lifted state (not more than 30 minutes in humid air). ), otherwise it will cause oxidation and corrosion of the cylinder barrel; dump trailers for sale near me in Philippines is strictly prohibited to disassemble and adjust the relief valve on the lift valve, otherwise the hydraulic system will lose its safety protection function and cause an accident;

4.When loading cargo, ensure that the vehicle is evenly loaded front to back and left and right. Loading dump trailers in Philippines too far forward will cause the hydraulic system to be overloaded. Loading cargo too far back will cause the vehicle to tip over when unloading. Unbalanced loading of dump trailers for sale near me in Philippines  to the left and right can easily strain the cylinder and roll over; the dump trailer for sale in Philippines When unloading, be sure to ensure that the unloading ground where the vehicle is located is solid and flat in the front, rear, left and right, that the dump trailers for sale near me in Philippines remains level and that the main vehicle and trailer are in a straight line.
