Product Description

Truck cranes Hydraulic frame support Cylinder for sale

1. High Load Capacity & Durability

• Heavy-Duty Construction: Made from high-strength steel to handle extreme bending and compressive forces.

• Long Stroke Lengths: Supports multi-stage telescoping booms (up to 50+ meters in large cranes).

2. Precision Control & Smooth Operation

• Proportional Valve Compatibility: Enables fine-tuned load positioning (critical for overhead powerline work).

• Buffered End-Stops: Reduces shock at full extension/retraction, preventing structural damage.

3. Compact & Lightweight Design

• Hollow Piston Rods: Reduce weight while maintaining strength (common in knuckle boom cranes).

• Space-Saving Integration: Fits within tight crane chassis designs.

4. Corrosion & Wear Resistance

• Hard-Chrome Plated Rods (25+ µm thickness) + Stainless Steel Options for marine/coastal use.

• Dust-Proof Seals protect against abrasive particles.

5. Safety Features

• Load-Holding Valves: Prevent dangerous drift during power loss (ISO 4413 compliant).

• Burst Protection: Reinforced welds and pressure relief valves for overload scenarios.

 

Primary Applications in Truck Cranes

1. Boom Telescoping & Luffing

• Main Boom Cylinders: Control extension/retraction in truck-mounted cranes.

• Jib Cylinders: Adjust auxiliary boom angles for precision lifts.

2. Stabilizer & Outrigger Systems

• Horizontal/Vertical Outrigger Cylinders: Provide stability on uneven terrain (up to 500+ kN force).

3. Load Moment Control

• Overload Protection Cylinders: Integrate with LMI (Load Moment Indicator) systems to prevent tipping.

4. Hook & Winch Positioning

• Telescopic Hook Cylinders: Enable remote hook height adjustment (used in utility cranes).

5. Specialized Functions

• Rotator Cylinders: For grapple/log cranes in forestry.

• Tilt Cylinders: Adjust platform angle in aerial bucket trucks.
