The American Crane Modular Norheim Hoist is the latest evolution in hoist design.
The modular Norheim Hoist is engineered for safety, reliability, and flexibility and is available in capacities from 1/2 ton to 160 tons. In addition, the hoist can be precisely adapted to meet your application requirements. The various application types - ranging from foot-mounted hoists, monorail hoists, and double rail trolleys - can be adapted to meet specific customer requirements.
As a standard, the hoist is rated for the (HMI) Hoist Manufacturers Institute Class H-4 and (CMAA) Crane Manufacturers Association of America Class D duty up to 60 tons, and CMAA Class A & B 70 Ton - 160 Ton. For Class E, F, and available custom designs consult the factory. The standard control configuration for the Norheim Hoist is the inverter drive, in conjunction with a compatible motor. A hoist inverter offers optimum utilization of the motor's output and allows very precise positioning of the load. This feature allows the lifting speed to increase for loads that weigh up to 30 percent of the rated load capacity for increased productivity. Two speed hoist and trolley control is available up to 20 HP.
Optional control contactors for two speed control are oversized to be suitable for HMI H4 and CMAA Class D service. The control enclosures are dust tight and water resistant to prevent the ingress of foreign material and non-corrosive liquids. All wiring is in accordance with NFPA NEC Article 610.
