Bucket Cylinder

#### **Product Overview**

This product is a high-performance bucket cylinder specially developed for DAEWOO DH series short-arm excavators (such as compact models like DH60, DH80). It has been optimized to meet the specific mechanical requirements of short-arm operations, providing maximum digging force and response speed within limited spaces. It is perfectly suitable for refined operations in municipal engineering, landscaping construction, and other scenarios.

### **Core Innovative Design** 

#### **1. Specialized Mechanical Optimization for Short Levers**

- Enhanced design of short levers (increases output force by 15% compared to standard type)

- Compact structure (reduces total length by 20%)

- Dual buffer valve configuration (suitable for high-frequency rapid reversing) 

#### 2. Precise Motion Control

- Starting force ≤ 0.3 MPa (Precise Micro-operation)

- Speed fluctuation rate < 5% (Continuous Speed Adjustment)

- Built-in displacement sensor (Optional) 

#### 3. Enhanced Durability System

- Supersonic喷涂 piston rod (HV1000+)

- Triple composite seals (main seal + emergency seal + dust-proof)

- Impact protection sleeve (polyurethane material
