Product Details

The Mobile Cantilever Crane is a modular heavy-duty lifting system designed for the most demanding industrial environments. Featuring a patented aluminum-steel hybrid girder construction, it delivers exceptional strength-to-weight ratio, reducing dead load on your facility's runway beams.

Available in single-girder (up to 20 T) and double-girder (up to 50 T) configurations, the KBK adapts to any layout — from tight indoor assembly lines to expansive outdoor storage yards. Each unit is engineered, fabricated, and load-tested in our ISO 9001 certified facility.

Remote radio control + pendant operation (dual-mode)
CE, ISO 9001, ASME B30.17, GB/T 3811 compliant

    Product Highlights

    Factory Floor Integration

    Factory Floor Integration

    Seamlessly integrates into existing production lines. Compact end-carriage design maximizes usable lifting height and minimizes headroom requirements to just 1.2 m.

    Precision Hoist Mechanism

    Precision Hoist Mechanism

    German-engineered wire rope hoist with VFD enables ±2 mm positioning accuracy. Dual-speed range: 0.8 m/min for micro-positioning, up to 8 m/min for rapid lifting.

    Robotic Welded Girder

    Robotic-Welded Main Girder

    Box-section girder fabricated by submerged-arc robotic welding. 100% UT-inspected seams ensure structural integrity at 150% overload test.

    CNC Precision Cutting

    CNC Precision Manufacturing

    All steel components plasma-cut and machined on CNC centers with ±0.5 mm tolerance, ensuring perfect fit during assembly.

    Manufacturing Process

    Step 1 — Material Preparation: High-strength steel plates (Q345B / S355JR) cut by CNC plasma & laser. All edges ground and inspected.

    Step 2 — Robotic Welding: Girder sections welded by submerged-arc robotic welders. All seams 100% inspected by ultrasonic testing.

    Step 3 — Assembly: End-carriages, hoist trolley, and electrical control panel assembled on precision jigs.

    Step 4 — Load Testing: Every crane undergoes 125% dynamic and 150% static load test before surface preparation.

    Step 5 — Painting & Shipping: Sandblasted to Sa2.5 grade, primed with zinc-rich epoxy, and finished with polyurethane topcoat.

    Installed a 32T double-girder KBK in our steel fabrication shop. The VFD control is incredibly smooth — our operators can position loads within centimeters. Build quality exceeded expectations. Highly recommend.

    We purchased two 10T single-girder KBK cranes for our warehouse. Installation was straightforward with the remote guidance. After 8 months of daily use, zero downtime. The self-lubricating rails really make a difference.

    The anti-corrosion treatment on these cranes is top-notch. Operating in a coastal shipyard for 14 months now with no rust issues. Customer support response time is impressive — always within a few hours.

    Good value for money. The crane itself is excellent. Only minor issue was a loose pendant connector on delivery, but the replacement arrived in 3 days. Very responsive after-sales team.

    Third KBK crane we've purchased. Same consistent quality every time. The modular design allowed us to easily extend the runway when we expanded our workshop. Will continue buying from this manufacturer.
