Project Varsteel Saskatoon

The project requirements was to design, supply, and Install

• (6) 10 ton CMAA Class D Top Running Double Girder Cranes for steel handling.  Each crane was fit with (2) 5 ton high speed hoists and all were remote control operated.
• All cranes motors were powered by Variable Frequency Drives for superior performance and motor control.  In addition, all hoists were fit with express speed feature, meaning that the hoists will operate in express speed when the carrying loads on the hooks are less than 25% capacity. For additional safety, the system includes a hoist synchronization system, to ensure both hoists operate at the same speed.  This prevents one hoist from operating in express speed while the second hoist is handling more than 25% capacity and hoisting at regular speed.
• Bridge wheels were machined from heavy steel and the wheel treads and flanges were flame hardened to prolong wheel life and reduce maintenance down time.
