USA-based Columbus McKinnon Corporation has launched a wire rope hoist series in the 25 to 50 tonne capacity range. The Yale Global Max HC is a double-girder type with a range of features that set it apart from that category, the manufacturer said.

The series has an external hoist motor designed to optimise cooling and maximise accessibility. The remote mounting of the hoist motor and brake prevents heat transfer in either direction, and allows for easy maintenance. The hoists also have a sealed, fully enclosed, pressure-tested gearbox with the gears submerged in oil for maximum protection. The hoist's unique, fully enclosed free loop guide is designed to specifically eliminate slack rope during operation, added Columbus McKinnon.

Optional features include a mechanical over-speed device, a block operated limit switch, and twin ropes for dual motor hoists.
