Client

Motonorte Indústria, São Paulo, Brazil – a manufacturer of heavy truck chassis and engine blocks.

Challenge

Motonorte’s production line relied on two aging 20‑ton single‑girder overhead cranes. Frequent breakdowns caused up to 6 hours of downtime per week. The limited lifting speed (only 3.5 m/min) created a bottleneck at the assembly station, restricting daily output to 28 chassis. Safety was also a concern – load sway led to two near‑miss incidents.

Solution from Henan Mine

Henan Mine designed and supplied a 50‑ton double‑girder overhead crane with:

Span: 25 m | Lifting height: 10 m | Duty class: A6 (heavy duty)

ABB VFDs for smooth acceleration and precise load positioning (±5 mm accuracy)

Anti‑sway technology and wire rope hoist with dual braking system

Smart control panel with remote diagnostics and overload protection (120% limit)

Modular rail design for easy installation over existing workshop columns

The crane was delivered in three 40‑ft containers, and Henan Mine’s engineer supervised on‑site assembly within 10 days.

Results

Production throughput +41% – from 28 to 39 chassis per shift

Downtime reduced by 78% (now <1.5 hours/week)

Zero safety incidents in 14 months of operation

Energy consumption 18% lower than the old cranes due to VFD and regenerative braking

ROI achieved in 9 months
