NORD, gearmotors for cranes
Throughout the world, manufacturers of cranes and trolleys rely on parallel shaft gearmotors from NORD DRIVESYSTEMS with power ratings up to 200 kW and a wide range of gear ratios.
Speeds are around 80 m/min for crane movement and 32 m/min for trolley movement, with accellerations of 0.2 m/sec. Two or three-stage basic types are available with hollow or solid shafts, in foot mounted, flange mounted or face mounted versions, each with the same housing. The unicase concept enables parallel shaft gear units with high output power and extremely compact gear unit dimensions. These in turn can be combined with many elements of the NORD modular system.
A further emphasis is on bevel gearboxes, usually with hollow shafts and torque arms. With this drive version, the large range of standard components also allows the gear unit to be precisely matched to the requirements of the application.
In addition to the high efficiency of gear units with helical, parallel shaft, bevel and wormgears, there are further benefits to operators: highest operational reliability, high output torques, high axial and radial load capacity, quiet running, high efficiency, reduced maintenance and longer operating life.
Additionally, products with protection classes IP55 and IP66 as well as rust and dust-protected versions with a special coating are used. Furthermore, gear units may are also befilled with synthetic oil if the cranes are to be used at high temperatures, for example in foundries.
Nord drivesystems has recently dedicate a complete website to the application for cranes: http://cranes.nord.com/cms/
