Power Electric Cable Hydraulic Puller
This SA-YQ420 Hydraulic Puller has an electronic control engine that strictly complies with the current Tier 3 emission standard of both European and American non-road mobile machinery.
Furthermore, our product provides numerous functions. For instance, the automatic braking function can ensure the safe operation, in case of the hydraulic failure caused by the sudden flameout of motor or other reasons.
Due to the hydraulic type rope clamping device, the reel can be changed conveniently. By utilizing the steel wire rope automatically winding device, it is really easy for loading and unloading. Also, the rope can be arranged automatically.
This SA-YQ420 Hydraulic Puller possesses infinitely variable pulling speed and traction force. The pull in the rope can be visually read on the line pull gauge. Additionally, our product has the overload automatic protection function. Users can set the maximum traction force in advance.
A hydraulic tractor is a mechanical device that uses a hydraulic system, usually used to pull and move heavy goods, vehicles, or machinery. The main function of this machine is to use the power provided by the hydraulic system to generate strong traction, which allows it to move and operate large loads efficiently in a variety of terrains and environments.
The working principle of the hydraulic tractor is to drive the hydraulic motor or cylinder through the high-pressure liquid generated by the hydraulic system, which generates enough force to push or pull the cargo. These machines usually have good control performance and can adjust the speed and traction as needed to adapt to different working scenarios.
The main features and advantages of hydraulic tractors include:
1. Strong traction: The hydraulic system can provide efficient and stable power output, so that the hydraulic tractor can produce strong traction and easily move large goods.
2. Flexibility and adjustability: hydraulic tractors usually have adjustable traction speed and force control functions, which can be adjusted according to actual needs, and are suitable for different work scenarios.
3. Wide applicability: hydraulic tractor can be used in a variety of terrain and environment, including flat, slope, uneven terrain, etc., with strong adaptability and versatility.
4. High safety: the hydraulic system has good control performance and stability, which can ensure the safety during operation and reduce the occurrence of accidents.
5. High efficiency and energy saving: compared with traditional mechanical transmission systems, hydraulic systems usually have higher efficiency and energy conversion rates, which can save energy consumption and operating costs.
In general, the hydraulic tractor is a powerful, flexible and reliable mechanical equipment, which is widely used in construction sites, logistics warehousing, port terminals and other occasions, providing an effective solution for cargo handling and movement.
