Daewoo bulldozer hydraulic cylinder

#### **Product Overview**

This product is a high-strength Hydraulic Actuator specially developed for the DAEWOO series crawler bulldozers. It is used to precisely control the lifting, tilting of the bulldozer blade and the operation of the loosening device. It is made of military-grade materials and features a heavy-duty structural design, meeting the high-strength operation requirements in extreme conditions such as mining and earthwork engineering. 

#### **Core Advantages** 

**1. Super-strong Impact Resistance Structure**

- The cylinder block is forged as a whole (made of 42CrMo alloy steel)

- The piston rod is laser-coated with WC layer (hardness ≥ HRC62)

- Dual safety valve redundancy design (35MPa main valve + 40MPa emergency valve) 

**2. Intelligent Hydraulic Control**

- Load-sensitive Flow Regulation (Energy Saving by 15%)

- Three-stage Buffer System (Patent No. ZL2023XXXXXX)

- Optional Electro-hydraulic Proportional Control (±1mm Accuracy) 

**3. All-weather Adaptability**

- Cold-weather type: -45℃ low-temperature start kit

- Tropical type: Sealed group resistant to 120℃ high temperature

- Minefield version: Armor sleeve resistant to stone impact
