Custom Jib and Hoist
Sydney Metro 2
August 27, 2020

Ranger designed, supplied, installed and certified Australian made freestanding and wall mounted custom jibs for the emergency egress and for materials handling. Ranger worked with the Sydney Metro engineering team to design a solution which included a 2500kg WLL, 6.5m underslung with 5m slew. The system also had to incorporate a mechanical and electrical twin braking system to comply with Australian Standards.  This was designed as a rescue device to help get injured personnel out of the tunnel shaft in the case of emergency. They were designed with a 45m height of lift to allow the crane to reach the bottom of the shafts

Due to the 35m height of lift, Ranger specified a GH 2500kg wire rope hoist from Europe to meet the duty cycle requirement.

As a remote and pendant operation was required, all movements were protected by electrical limit switches.
