The role of PTO system (power take-off) in trailers is to provide additional drive capacity for the trailer by extracting power from the main engine of the vehicle, driving hydraulic pumps, compressors and other equipment, thereby enhancing the versatility and operational efficiency of the trailer
Features of the PTO system:
1. Versatility: PTO system can extract power from the vehicle’s main engine to drive hydraulic pumps, compressors and other equipment, improving the vehicle’s versatility
2. Safe operation The use of PTO systems must strictly comply with safety regulations, as high-speed rotating drive shafts and components may cause serious mechanical damage or personal injury. Operate with a clear view of all personnel away from the rotating part and the device in a secure lock
3. Control mode: PTO switch is the core device that controls the start and stop of the PTO system, and the driver starts or stops the PTO function by pressing or toggling the switch, which is usually operated when the vehicle is stopped or driving at low speed
electrohydraulic proportional valve-controlled motor
Electro-hydraulic proportional valve is an electronic control element in a hydraulic transmission system, which inputs electrical signals into the electromagnet and controls the movement of the valve core through electromagnetic force, thereby changing the on-off state of the valve port. Electro-hydraulic valves are suitable for applications that require high-precision control and fine adjustment.
Electro-hydraulic valves are suitable for applications that require high-precision control and fine adjustment because they can continuously and proportionally control the force, speed and direction of movement of hydraulic mechanisms, and can prevent shock phenomena caused by changes in pressure or speed or when the direction of motion is changed
It enables high-precision control and regulation for complex hydraulic systems
Sistema de frenos de aire air brake system: La inclusión de un sistema de frenos de aire mejora la seguridad durante el funcionamiento y el transporte. Esta característica garantiza una potencia de frenado efectiva, lo que brinda tranquilidad a los operadores al maniobrar en pendientes o durante el viaje en carreteras públicas
Due to their strong braking power and fast reaction time, air brake systems are commonly used in large trucks, buses and heavy machinery. These vehicles require more braking power and faster reaction times to ensure safety
