6.3 Ton Knuckle Boom Truck Mounted Crane

6.3-Ton Knuckle Boom Truck-Mounted Crane (F130K-04)

When operating in urban streets or confined job sites, telescopic boom cranes often require significant space once extended, making them ill-suited for tight lifting environments. You may require lifting equipment that is lightweight and compact to install, yet capable of supporting various attachments. The F130K-04 knuckle boom crane was developed precisely for these needs. It features a maximum lifting capacity of 6,300 kg, a rated lifting moment of 13.0 ton-meters, 400° continuous rotation, and a maximum hydraulic working outreach of 9.8 meters. Weighing 2,200 kg and requiring only 1,050 mm of mounting space, its compact folded design fits mainstream medium-duty truck chassis while preserving ample cargo bed space. As a truck-mounted knuckle boom crane, it belongs to the land-based application category, distinct from ship-based telescopic or knuckle boom cranes. The unit includes an interface for attachments, such as a grapple, enabling it to function as a forestry crane for log handling and transport. Optional features—including remote control, a hydraulic winch, an aerial work basket, and a load moment limiter—are available to meet specific requirements. Suitable for applications ranging from construction material handling and municipal maintenance to logistics loading and unloading, the crane delivers stable hydraulic performance and is built for long-term, high-frequency field operations.

Product Features

1. Lightweight main structure (total weight: 2,200 kg) reduces chassis load; designed to handle both cargo transport and lifting operations.

2. Features continuous wide-angle rotation and a 9.8m operating radius; ideal for lifting tasks in confined spaces such as narrow alleys or courtyards.

Usage Tips

1. Fully extend outriggers and level the vehicle before lifting; strictly adhere to the load chart during operation—exceeding rated moment limits is prohibited.

2. Hydraulic system pressure is 28 MPa; recommended power input is 22 kW. Regularly inspect hydraulic lines and promptly replace aging seals.

FAQ

Q1: Does the hydraulic system have specific flow rate requirements when connecting to the vehicle's PTO (Power Take-Off)?

A: The system requires a flow rate of 35 L/min. Use this as the benchmark when selecting the PTO; proper flow matching ensures stable crane operation speeds.

Q2: Is the hydraulic system pressure-tested and calibrated before the crane leaves the factory?

A: Yes, the entire unit undergoes hydraulic pressure testing and no-load functional testing before shipment. It is only dispatched after passing all inspections; upon delivery, only the PTO and hydraulic line connections are required.

Q3: Are there additional structural reinforcement requirements when using an optional man basket for aerial work?

A: When using a man basket attachment, the moment limiter must be activated, and the basket's rated load strictly observed; additionally, inspect the hinge pins for wear.

Q4: Are the hydraulic interface standards compatible if I need to replace or add attachments later?

A: The hydraulic interfaces use industry-standard specifications. Adding attachments—such as a grapple—requires only connecting the hydraulic lines; no modifications to the crane's main structure are necessary.
