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.
Key Features
Product Highlights
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
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 Main Girder
Box-section girder fabricated by submerged-arc robotic welding. 100% UT-inspected seams ensure structural integrity at 150% overload test.
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.
