Heavy Duty 20 tonne pulley with 450mm pulley wheel diameter

To eliminate excessive lead times and high procurement costs, BMS designed and manufactured a bespoke heavy-duty, 20 tonne cable pulley assembly featuring reinforced structural bracing for cables up to 44mm diameter. Designed for maximum operational safety and cable retention, the custom solution delivered a 2-week turnaround and significant cost savings.

Commercial challenge when procuring specialised large-diameter pulleys for heavy-lifting

When high market prices and excessive lead times created significant friction for acquiring heavy-duty cable pulleys, BMS leveraged in-house design and manufacturing capabilities to develop a high-performance alternative.

The engineering solution

BMS engineered an optimized pulley assembly designed for continuous, heavy-duty deployment. The resulting pulley system delivers superior structural stability, enhanced cable containment safety, and accelerated turnaround - at a fraction of standard commercial costs.

Robust capacity: Built to handle cable diameter is up to 44 mm in diameter running across a 450mm diameter pulley wheel.

Enhanced structural bracing: We have added additional bracing with four large bosses which give a lot more stability to the design than other products on the market. These also make it safer if there was an issue with the steel rope. It keeps the rope held within the pulley system, which adds additional safety.

Streamlined fabrication: We can manufacture these steel pulleys for around £3500 with a 2 week lead time.
