The Choice for Built-Up Class D Cranes

With hoist capacities from 5-30 tons, and pre-engineered spans up to 100 feet for single or dual trolley configurations, Whiting will deliver an EV Crane quickly to fit your production schedule. Whiting’s engineering team translated their experience building heavy-duty cranes into a robust and cost-competitive built-up CMAA Class “D” crane. The EV Crane is the solution for businesses looking for a built-up lifting system without busting the budget or settling for a substandard packaged hoist.

Why Does Whiting Use True Closed Loop Vectors on All of Their Hoists

Safety and Absolute Control

Closed Loop controls utilize a motor shaft-mounted encoder that provides constant feedback. This allows for continuous full torque at zero speed. Using a rugged and highly responsive 1024 PPR encoder, the crane operator can hold the position of a load while moving it without setting the brake. This efficient process lengthens the life of the mechanical brake by minimizing its actuations.

Whiting’s Closed Loop controls also monitor the condition of the hoist brake. The controls will counter-torque against the brake before the hoist is used. If it holds, then the operator can move the load without issue. It not, it causes a fault and alerts the operator to a potential brake issue while giving them an opportunity to move the load to safety. This monitoring catches potential hoist brake issues before they turn into catastrophic failures.
