Truck Mounted Crane 6.3 Ton

The truck mounted crane 6.3 ton is a compact yet powerful lifting solution, designed for medium-duty applications across construction, utilities, logistics, and infrastructure projects. Mounted on a commercial truck chassis and powered by the vehicle's engine through a power take-off (PTO), this crane combines mobility with efficient, self-contained lifting capability. Available with telescopic (straight) or knuckle (articulating) boom configurations, it handles loads up to 6,300 kg with working radii up to 10–12 meters, making it a versatile choice for diverse job sites.

1. Durable Construction & Advanced Design

6.3-ton cranes are engineered with high-strength materials and proven design features:

• Hexagonal or U-section boom technology for better neutrality and cross-sectional bending resistance
• HG785 high-strength steel for lightweight yet robust boom construction

• Flange telescopic arm connection structure for increased lifting capacity

• Floating three-point bridge structure design reduces chassis frame stress during vehicle operation

2. Core Components & Hydraulic System

• Hydraulic Pump & Valves: Options from internationally recognized brands (HYDAC, Eaton, Vickers) or domestic quality suppliers
• System Pressure: Typically 20–28 MPa for reliable lifting force

• Oil Tank Capacity: Approximately 90 liters

• Hoist System: Options with imported Italian winch systems for smooth, controlled lifting

3. Safety & Control Features (XCMG SQ6.3SK2Q as example)

Leading models incorporate advanced safety technologies:

• Throttle Control System: Synchronized bilateral handle with automatic acceleration/deceleration for smooth lifting operations
• Automatic Hook Device: Minimizes preparation time and prevents crane damage during transport

• Hoisting Overwinder Device: Prevents hook block from contacting boom tip, protects against wire rope breakage

• Slewing Locking Device: Prevents boom sway during vehicle travel

• Torque Limiter (Optional): Overload protection against vehicle rollover or crane damage
