Introduction to Telescopic Crane Booms

We specialize in the R&D, design, manufacturing, and sales of truck cranes, truck-mounted cranes, telescopic crane booms for various applications, and structural components for construction machinery. Leveraging superior manufacturing processes, our crane booms and structural components are widely used across numerous sectors, including construction, cement, electric power, warehousing, logistics, agriculture, port operations, and marine machinery.

Scope of Business for Hoisting Machinery Booms

We provide comprehensive services for structural components of construction machinery, offering end-to-end solutions that cover everything from design and production to maintenance.

As a trusted OEM-qualified supplier, we manufacture premium structural components for construction machinery, including 1.5-to-300-ton telescopic booms (polygonal/U-shaped) and matching turntables for major brands like Zoomlion, XCMG, SANY, and Changjiang. We offer custom manufacturing based on client-provided vehicle models and years, delivering imported or domestic booms and turntables within an efficient three-day turnaround. We welcome clients to visit our facilities for on-site inspections and business collaborations.

We offer flexible custom manufacturing and design modification services based on client requirements.

Fast Quoting: Clients can submit basic drawings for price inquiries, and we provide tailored quotes within 24 hours based on process complexity.
Tailored Design: We fully customize or modify equipment—such as telescopic booms, turntables, and outriggers—according to client-specified operational constraints (e.g., maximum boom length, section size, swing radius, and outrigger span).

Current market trends show an increasing demand for greater crane extension heights. Consequently, some users wish to upgrade their existing two-section boom cranes to three-section booms, or three-section booms to four-section booms, in order to align their equipment with market needs and generate higher returns.

Leveraging over 20 years of experience, our technical team delivers prompt, definitive diagnostics and repairs for persistent truck crane faults that other shops fail to resolve. We offer a fast, cost-effective alternative to slow and expensive OEM services, specializing in restoring deformed or damaged telescopic booms to full operation with minimal downtime.

Production equipment

Equipped with advanced machinery, comprehensive manufacturing systems, and cutting-edge technology, we rigorously control every detail to ensure high-quality and reliable products. Committed to continuous improvement and growth, we constantly optimize our processes to refine and strengthen our lean production capabilities.

High-standard bending precision ensures product quality and production efficiency.

With a length of 8.5 meters, a width of 4.5 meters, and a height of 2.5 meters, it meets the processing requirements for large structural components.

With a length of 15 meters, it improves the assembly precision of the maintenance boom sections.

Length of 24 meters and width of 5.5 meters; high-precision cutting ensures the accuracy of components.

Processing technology

We possess comprehensive processing workflows, ensuring that every stage meets high-standard quality requirements.
