We love nothing better than to completely modernize an existing crane to gain lower maintenance costs and more production. But sometimes the demands of the business means that improvements must be segmented in order to optimize capital. On this project, the customer was faced with just that problem so Engineered Lifting Systems went to work on getting the end user the most “Bang for the Buck”.
The existing P&H crane has two trolleys using Balance Design hoist units with wound rotor motor five speed trolley control, and wound rotor motor hoist with Magnetorque Eddy Current dynamic load brake, also five speed control. Because in large part of the old contactor based control, the crane used parts and needed repairs and adjustments that repeatedly cut into the budget and production time. In order to maximize the capital spent, only the hoists and trolleys were updated at this time.
