KSQZ300 12Ton 4 Section Square Boom Truck Mounted Crane, Full Hydraulic 360° Rotary Lifting Crane for Municipal & Rural Construction

Product Description

KSQZ300 full hydraulic truck mounted crane is a practical and cost-effective lifting equipment developed for medium and small-scale daily hoisting demands. Equipped with a 4-section synchronous telescopic square boom, the machine features a compact body and flexible operation, solving the hoisting difficulties of narrow working spaces where large cranes cannot operate. The optimized boom design realizes stable telescopic movement and moderate working coverage, fully meeting conventional construction, municipal maintenance and cargo handling requirements.

The whole machine adopts high-quality structural steel welding and reinforced square boom integration technology, with excellent rigidity, anti-deformation and anti-torsion performance under medium load operation. Matched with a high-efficiency standard hydraulic motor and precision slewing reducer, the crane achieves smooth lifting, stable 360° continuous rotation and accurate positioning. The reasonable outrigger layout provides stable supporting performance, effectively ensuring operational safety during daily full-load working conditions.

This crane is equipped with a practical heat dissipation system to avoid hydraulic overheating during continuous daily operation. It supports dual operation modes of on-site manual control and wireless remote control, with simple operation and sensitive response. All core hydraulic components and structural parts undergo strict factory pressure testing and quality inspection before delivery. With low failure rate, convenient maintenance and long service life, it fully adapts to long-term frequent daily commercial and engineering applications.

FAQ

Q1: Is KSQZ300 a complete crane or auxiliary spare parts?

A1: The KSQZ300 is a complete finished truck mounted crane unit, not accessories or spare parts. It is fully assembled, hydraulic tested and factory debugged, ready for direct installation on medium-duty truck chassis and immediate field operation.

Q2: What is the actual lifting capacity and working range of KSQZ300?

A2: This is a 12-ton medium-duty crane with a maximum lifting torque of 300kN·m, maximum working height of 19.8m and maximum working radius of 17.2m. The 4-section telescopic boom fully meets daily small and medium-sized engineering hoisting and high-altitude operation demands.

Q3: What is the advantage of square boom crane compared with hexagonal boom?

A3: The square boom features simpler structure, lower cost, more convenient maintenance and lighter body. It is more suitable for daily frequent conventional hoisting and narrow-site operation, with higher cost performance for small project use and equipment leasing.

Q4: What operation modes does KSQZ300 support?

A4: It supports dual operation modes of wireless remote control and manual emergency operation. The remote control enables flexible and safe long-distance operation, while the manual mode serves as a backup to ensure normal operation in special situations.

Q5: What kind of truck chassis is suitable for this crane?

A5: The KSQZ300 adopts standard universal interface, compatible with most mainstream medium-duty truck chassis. It features light weight and small installation space, with low requirements for chassis bearing capacity, suitable for various daily transport and engineering trucks.

Q6: What export certificates can you provide?

A6: We can provide CE, ISO9001 certification, factory test reports, quality inspection documents and complete customs clearance materials to support smooth export and global customs clearance.

Q7: How about the delivery cycle and packaging?

A7: Standard models are in stock with delivery within 7-12 working days. Adopt professional export anti-rust treatment, waterproof packaging and fixed reinforcement to avoid damage during long-distance transportation.

Q8: What after-sales support is provided?

A8: We provide 1-year full machine warranty, lifelong free technical consultation and remote fault guidance. We support fast supply of matching accessories to ensure long-term stable operation of the equipment.
