XCMG bulldozer hydraulic cylinder

#### **Product Overview**

This product is a high-performance Hydraulic Actuator specially developed for XG/XT series crawler bulldozers of XCMG. It is made of military-grade materials and features a heavy-duty structural design, suitable for extreme working conditions such as mining and earthwork projects. It meets the high-strength power requirements for the lifting, tilting of the plow and the operation of the loosening device. 

#### **Core Advantages** 

**1. Super-strong bearing structure**

- 45# steel fully forged cylinder (wall thickness ≥ 25mm)

- Ultra-sonic spraying WC coating on piston rod (hardness ≥ HRC65)

- Dual safety valve redundant design (main valve 35MPa + emergency valve 42MPa) 

**2. Intelligent Control System**

- Three-stage hydraulic buffering (Patent No. ZL2023XXXXXX)

- Load-sensitive flow regulation (energy saving by 18%)

- Optional electro-hydraulic proportional control (±0.5° angle accuracy) 

**3. Adaptation to Extreme Conditions**

- Mining version: Anti-crush armor cover + ceramic coating

- Cold region version: -45℃ low-temperature starting system

- Tropical version: Resistant to 120℃ high temperature sealed components
