MAXTECH has recently completed production and shipped another 3‑ton@12‑metre knuckle boom telescopic crane. As one of the star products in MAXTECH's portfolio, this model continues to win favour with customers worldwide thanks to its compact stowage and flexible operation.
Market Performance: Over 20 Units Shipped in Two Years, with Inquiries Continuing to Rise
The 3‑ton@12‑metre knuckle boom telescopic crane is one of MAXTECH's most popular marine crane solutions. Over the past two years, cumulative shipments of this model have exceeded 20 units, with orders continuing to grow. Since the beginning of this year, enquiries from shipowners, shipyards, and equipment rental companies have increased significantly, and market demand remains strong. The product has been successfully delivered to multiple regions including Europe, Southeast Asia, and the Middle East, with consistent customer feedback highlighting its compact folding design, flexible operation, and low failure rate.
Why Is This Model So Popular?
The sustained popularity of this 3‑ton/12‑metre knuckle boom telescopic crane lies in its excellent balance across three dimensions: space utilisation, operational flexibility, and reliability.
1. Flexible Operation – One Machine, Multiple Uses
Unlike traditional straight‑boom cranes, the knuckle boom telescopic crane features an articulated arm design that allows the boom to fold and extend like a joint. Operators can easily manoeuvre around deck obstacles, reach into confined spaces, and position loads with precision. From daily supply transfers, spare parts and equipment lifting, to hatch cover operation and container handling (with spreader attachment), a single machine meets a wide variety of vessel needs.
2. Compact Stowage – Maximises Valuable Deck Space
For vessels where deck space is at a premium, the greatest advantage of this crane is its extremely low stowed height. The boom can be fully folded without obstructing the helmsman's view, while freeing up maximum deck space for other operations. This feature makes it particularly popular on container ships, offshore support vessels, and other vessel types with limited deck space.
3. Proven Reliability
This model has passed rigorous factory inspection by Bureau Veritas (BV) , covering the four core functions of hoisting, luffing, slewing, and telescoping. During durability testing, the multi‑section alloy boom can extend to 12 metres in seconds, with stable and reliable connection structures even under full load. Thanks to corrosion‑resistant materials and sealed design, the crane can reliably withstand harsh marine conditions including high temperatures, high salt‑spray, high humidity, and strong winds.
