Bargteheide – Throughout the world, manufacturers of cranes equip all crane types and sizes with efficient and safe drive technology from NORD DRIVESYSTEMS. Now, there is a new web address dedicated to this industry. The cranes.nord.com microsite presents solutions and products and provides access to NORD’s extensive online services, e.g. individual configuration of drive systems. Additionally, NORD’s large sales network ensures optimal avail-ability and individual consulting and support.
Cranes and trolleys employ NORD’s helical parallel-shaft geared motors with power ratings up to 200 kW and a wide range of gear ratios. Speeds are about 80 m/min for crane movement and 32 m/min for trolley movement, with an acceleration 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 ver-sions, each with the same housing. The UNICASE concept enables high per-formance helical parallel-shaft gear units with extremely compact dimensions. They can be combined with many components from the modular NORD sys-tem.
A further emphasis in crane applications is on helical-bevel gear units, 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 worm gears, there are further essential benefits to operators: maximum operational reliability, high output torques, high axial and radial load capacity, quiet running, high efficiency, minimal maintenance, and long operating life. Products with protection classes IP55 and IP66 as well as rust and dust-protected versions with a special coating are optionally available. Furthermore, gear units can be filled with synthetic oil, if cranes are to be used in high temperatures, e.g. in foundries.
