ABM hoist drives are designed for decades of exposure to extreme ambient conditions. Drives are low maintenance because they are not easily accessible. They incorporate experiences from other application fields with extreme demands on availability, durability, and safety; demonstrated with more than 500,000 overhead crane drives manufactured in over 25 years. Custom ABM Drives are suitable for ambient temperatures down to -40°F (-40°C).
Hoist drive units lift loads between 3.2 and 40 mt. Designed for industrial cranes, dual-speed versions are powered by 2.5 to 20 kW asynchronous cylindrical-rotor motors with torque transmitted by 3-stage aluminum parallel shaft gearboxes. Units are suited for lifting speeds of 13 to 26 ft/min (4 to 8 m/min) at drum diameters of 5.5 to 16 in. (140 to 405 mm) and 4/1 reeving. Inverter-controlled GH40000 40 metric ton versions, equipped with 38 kW motor with encoder feedback, allow for lifting speeds of 16 ft/min (4.9 m/min) (higher lifting speeds up to 25 ft/min (7.6 m/min) are possible with reduced lifting weights) at 4/1 reeving. A wear-resistant dual surface safety brake is standard.
