Product Description

Function

As the core actuator of the truck-mounted crane, the luffing cylinder controls the pitching angle of the boom precisely through telescopic movement. It realizes boom lifting, amplitude adjustment and heavy load hoisting, determines the working radius and lifting height, and provides stable thrust to ensure safe and stable lifting operations.

Advantages

1. High Strength & Durability: Adopt high-strength alloy steel, suitable for heavy-duty and impact working conditions with long service life.

2. Stable Operation: Equipped with premium sealing parts and hydraulic lock, no cylinder slipping or jitter during operation.

3. High Safety: Built-in load-holding and overload protection devices, effectively avoid accidental risks.

4. Compact Design: Lightweight and compact structure, no impact on the vehicle’s load capacity.

5. Wide Adaptability: Compatible with mainstream straight and folding boom truck cranes, customization is available.

General Flow & Hydraulic Parameters

• Recommended system flow: 65–100 L/min
• Rated working pressure: 25–32 MPa (Standard: 31.5 MPa)
• Cylinder bore: 100–200 mm
• Piston rod diameter: 70–140 mm
• Standard stroke: 500–2500 mm
• Luffing angle: 0°–75° (up to 80° for folding boom cranes)

This parameter range fits luffing cylinders for 5–20 ton truck-mounted cranes of XCMG, Sany, Zoomlion and Furukawa full series.

Note: The flow rate can be matched with appropriate hydraulic pumps and valves according to crane tonnage and actual working conditions.

Internal Parts of Luffing Cylinder

We provide original-quality luffing cylinder assemblies as well as genuine internal spare parts for luffing cylinders. Custom service is also available for both complete cylinder assemblies and internal components.

You only need to send us the relevant parameters and dimensions, and we can arrange production and order processing according to your requirements.

There are numerous brands of truck-mounted cranes on the market. Each brand adopts different dimensions for its luffing cylinder and internal spare parts, so it is impossible to set a unified fixed price.

The prices shown on the website are for reference only. Please contact us for an accurate quotation before placing your order. We will offer you the exact price based on your specific model, size and actual demand.
