Advantages of the Front-mounted Hydraulic Cylinder for Dump Trucks

Advantages of the Front-mounted Hydraulic Cylinder for Dump Trucks

1. Superior Lifting Performance

Small lifting force with high lateral stiffness of the carriage: for the same lifting load, the front-mounted hydraulic cylinder has a relatively smaller lifting force; that is, it has a relatively small impact on vehicle structures, such as the top seat position and girders. Meanwhile, during lifting, the carriage shows high lateral stiffness, which is conducive to keeping the carriage stable.

The front-mounted hydraulic jack adopts a large single-cylinder dump jack. It uses the lever principle in its application, which makes lifting easy.

2. Structural Design and Durability

Multi-stage sleeve design: Front-mounted cylinders normally use a multi-stage sleeve design. This not only improves the bearing capacity of the hydraulic cylinder but also makes its structure more compact.

High-quality material: Most of the materials of every stage of the sleeve are high-quality, high-precision special steel pipe materials such as 27SiMn. Through strict processing and surface treatment, for example, chrome plating, the hydraulic cylinder boasts excellent bending resistance, rust resistance, and wear resistance, so its life span is extended.

Excellent sealing performance: using new sealing rings and combined sealing structure-for example, KI 310 high-pressure main sealing ring + Y-type low-pressure auxiliary sealing ring + PRW1 scraping, waterproofing, and dustproof combined sealing structure- effectively avoids leakage that may be caused in severe environmental conditions.

3. Adaptability and Flexibility

Various connection ways: front-mounted cylinders adopt various connection ways, including double hinge shafts, and double earrings, which can flexibly meet the needs of different models of a dump truck.

They have a wide range of applications: front-mounted hydraulic jacks are especially suitable for urban muck trucks with longer body wheelbases and carriage lengths, together with dump trucks with larger cargo boxes. Simultaneously, their sturdy cylinder blocks and excellent hydraulic capability make them popular for multi-purpose construction site vehicles and heavy vehicles.

4. Reasonable Space Utilization and Layout

Reasonable layout of the hydraulic oil tank: In order to avoid excessively long hydraulic oil pipes, the hydraulic oil tank of the front-mounted jack is always laid behind the cab and at the front of the carriage. The layout of the system saves space and allows for normal operation of the hydraulic system. Stable support surface: the support surface of the front-mounted hydraulic jack is the front plate of the carriage, and a thick iron plate is usually used to lock the hydraulic jack tightly at the supporting point to ensure stability during lifting.
