F500KC-07 25 Ton Knuckle Boom Loader Crane

F500KC-07 25-Ton Seven-Section Knuckle Boom Loader Crane

In confined spaces, standard telescopic boom cranes are often restricted by their physical dimensions, making precise lifting operations difficult. Many buyers find it challenging to select a crane that balances unit weight, lifting capacity, and versatility across various operational environments. Our F500KC-07 25-ton knuckle boom loader crane addresses these issues. Featuring a seven-section folding boom, a 62.5 ton-meter lifting moment, and a 360° continuous slewing system, it offers a maximum working radius of 14.5 meters. With a total unit weight of 7,850 kg, it operates flexibly within limited installation spaces, effectively replacing multiple single-purpose lifting devices to meet a wide range of engineering requirements.

This knuckle boom crane utilizes a hydraulic system with a rated pressure of 31.5 MPa and a recommended flow rate of 80 L/min. It supports various optional attachments, including remote control systems, hydraulic winches, personnel baskets, and grapples. When equipped with a grapple, it functions as a material-handling machine; by swapping in a timber-handling attachment, it transforms into a forestry crane. It is ideally suited for tasks such as civil construction in tight areas, self-loading and unloading of cargo, maintenance of power and telecommunications infrastructure, and the relocation of factory equipment. Its compact, folded configuration ensures a small footprint, allowing for easy transport when mounted on a truck chassis. Capable of handling lifting, aerial work, and material handling, this crane is an excellent solution for international and domestic engineering contractors, logistics fleets, and municipal agencies.

Product Features

1. Equipped with a 7-section folding boom, offering a 62.5 ton-meter (t·m) lifting moment and a maximum rated lifting capacity of 25 tons. It features 360° continuous rotation with no blind spots and a maximum working radius of 14.5 meters.

2. The unit weighs 7,850 kg and has an installation width of 1,500 mm. Its lightweight design minimizes the impact on the chassis's payload capacity, making it compatible with a wide range of mainstream truck chassis.

3. Highly versatile with excellent expandability; it supports various attachments—such as personnel baskets, grapples, and hydraulic winches—allowing a single unit to perform multiple types of operations.

Tips

1. Before beginning operations, ensure all outriggers are fully extended and the unit is leveled. Always verify the safe lifting capacity for the specific working radius by referring to the load chart; overloading is strictly prohibited.

2. When the unit is to remain idle for an extended period, fully retract and fold the boom. Protect hydraulic lines and pivot points from dust and debris, and apply grease regularly.

FAQ

Q1: What is the key difference between this model and a telescopic boom crane?

A1: A telescopic boom crane relies on a straight, extending boom, which is advantageous in open areas. This model features a folding (knuckle) boom, offering superior flexibility in confined spaces—such as narrow lanes, low-ceiling workshops, or dense urban environments—and is capable of performing lifts at negative angles (below the horizontal plane).

Q2: What is the warranty period, and is technical support available for overseas purchases?

A2：The unit comes with a standard warranty. A full set of technical drawings and hydraulic schematics is included. We provide remote video-based commissioning guidance, and spare parts can be shipped separately.

Q3: Can this be converted into a marine knuckle boom crane for use on a vessel?

A3: While the core structure of the crane is the same, marine applications require additional anti-corrosion and waterproofing upgrades. We can provide a modification plan tailored to marine operating conditions.

Q4: Are attachments like grapples or forestry (timber-handling) grapples included as standard equipment?

A4: Grapples and log-handling attachments are optional accessories. You may confirm the list of attachments when placing your order, and they will be supplied, installed, and tested as part of the delivery.

Q5: Which components should be the primary focus for routine maintenance?

A5: Regular inspections should focus on the cleanliness of the hydraulic oil, cylinder seals, the slewing bearing, and the lubrication points at the arm-section joints. Additionally, ensure that hydraulic oil filter elements are replaced on schedule to prevent hydraulic system malfunctions.
