Jib Crane
Heavy-Duty Electric Rotating Floor Mounted Jib Crane
Product Overview
Engineered for continuous, heavy-duty industrial lifting operations, our Electric Rotating Floor Mounted Jib Crane delivers superior structural rigidity, minimal arm deflection, and seamless 360-degree motorized rotation. Designed with precision-milled slewing drives, heavy-wall seamless pipe columns, and FEA-optimized boom structures, this self-standing pillar crane ensures accurate positioning and smooth material handling in demanding manufacturing environments.
Key Structural & Engineering Features
- Seamless Pillar Construction: High-grade Q235B/Q355B seamless steel column welded to a heavy-gauge base plate, engineered to withstand extreme bending moments and dynamic stress.
- FEA-Optimized Boom Design: Choice of precision I-Beam or Box Girder construction optimized via Finite Element Analysis (FEA) for maximum load capacity with minimal deadweight.
- 360° Motorized Slewing Drive: Driven by a high-torque slewing reducer with hardened gear ring. Integrated Variable Frequency Drive (VFD) provides soft-start and soft-stop rotation to eliminate load sway.
- High-Precision Hoisting Unit: Fully compatible with low-headroom wire rope hoists or electric chain hoists featuring dual lifting speeds (fast primary / slow creeping speed).
