PROJECT OF THE MONTH
Left: 3.2t SWL Stahl electric wire rope hoist installation.
Left middle: For the short-term installation phase, Hoist & Winch supplied a 10t safe working load (SWL) JDN air-powered chain hoist offering 30m of lifting height.
enabled engineers to mount the hoist trolley safely to the runway beam by initially opening and then closing the trolley width around the beam section. Following installation checks and connecting the air supply, Hoist & Winch performed dynamic load testing of both the hoist and runway beam using a 10t test load over the full 30m lifting height. This process was followed by a 125% static proof load test at low level. With testing successfully complete, Hoist & Winch delivered operator handover training to the installation contractors responsible for lifting the mill’s process plant equipment into position. Phase 2 of the project involved removing the
temporary air-powered hoist and installing the permanent lifting solution: a 3.2t SWL Stahl electric wire rope hoist with 30m lifting height. Mounted on a motor-powered trolley and operating with a single rope fall, the hoist unit delivers a very high main lifting speed of 16 m/min to minimise plant downtime during maintenance lifts through the access shaft and 2.6 m/min slow lifting speed for precise load laydown at the load landing level. Hoist & Winch conducted installation, commissioning,
load testing and LOLER certification of the permanent hoist system, before providing handover training for the mill’s maintenance personnel. “Projects like this demonstrate the value of careful
planning and technical collaboration to deliver safe, efficient lifting solutions that support both the construction and long-term operation of complex industrial facilities,” says Hoist & Winch Director Andy Allen. “We subsequently secured the contract for annual hoist inspection and maintenance.”

contractor constructed a platform over the lift shaft in accordance with Hoist & Winch specifications. The 10t air-powered hoist unit was raised to installation level using a temporarily mounted 2t SWL JDN air-powered chain hoist fixed to the underside of the runway beam. Once positioned beneath the beam, installation of the 10t hoist took place using a dedicated lifting arrangement comprising a pair of T-shaped lifting frames and four 1t SWL manual chain blocks.
