Stacker/Reclaimer Maintenance Using a Synchronous Hydraulic Lift System

A mining plant required precise lifting and separation of a large stacker/reclaimer turret to replace a worn slew bearing. A synchronized hydraulic lifting system was used to lift the equipment within a narrow tolerance, enabling safe and controlled maintenance of the bearing assembly.

A power plant operating a 240T stacker/reclaimer needed to replace a worn slew bearing as part of scheduled maintenance. The bearing replacement required the turret to be lifted and separated with extreme precision to allow access for servicing.

The stacker/reclaimer turret had to be lifted within a narrow tolerance to avoid misalignment or damage during separation. The size and weight of the equipment, combined with tight maintenance clearances, made controlled, synchronized lifting essential for safety and success.

A synchronized hydraulic lifting solution was deployed using eight RD1006 hydraulic cylinders controlled by an 8-point Motion Control System (MCS). Hydraulic power was supplied by a Power Team PE554S electric hydraulic pump, delivering consistent flow and pressure to the MCS to enable smooth, synchronized movement across all lifting points.
This type of maintenance challenge is solved using a multi-point synchronized hydraulic lifting system powered by a centralized electric hydraulic pump, which distributes load evenly and maintains precise control when handling large rotating equipment.

The synchronized hydraulic lifting system enabled accurate lifting and separation of the stacker/reclaimer turret, allowing the slew bearing to be replaced safely and efficiently. The controlled process minimized risk, reduced downtime, and supported reliable return to operation.

By using a synchronized multi point hydraulic lifting system instead of conventional single point methods, maintenance teams typically reduce alignment adjustments and lift related delays by approximately 20–30%. Controlled, level lifting also helps shorten outage duration and can reduce total maintenance downtime by an estimated 15–25%. Improved load control significantly lowers the risk of binding or uneven loading, supporting safer execution and more predictable completion of large stacker/reclaimer maintenance activities.
