(Adapted Speed Range) (Extended Speed Range) This option enables hoist speed to be automatically adapted to the hook suspended load.

Type S (ESR) motors can be operated at full speed at up to 40% of the rated load, the max. motor speed remaining at 3000 rpm. At 20% of the load, the rated speed is the equivalent of 150% of listed speed. With nominal load, the rated speed is the equivalent of the listed speed. Product advantages > Up to 50% energy savings > Speed depending on load obtained automatically. > Productivity and safety enhancement. > Enhancement of load travel accuracy. > Best return on investment. > ptimal use of work space and of approach data of O hook. > Increased motor life span. > se of low amperage for crane power supply to U reduce the cost of investment in power-feeding systems. > epending on standards and local tax systems, D grants can be obtained within the framework of energy saving policies. Product advantages > aximum ESR speed, 1.5 times greater than M standard speed. > Productivity enhancement. > Enhancement of load travel accuracy. > ptimal use of work space and approach data of O hook.
