SLM Type Suspension Type

Hitachi trackless trolley is the latest model that the latest technology is applied to our experiences. Polyurethane Rubber is used for the wheels. It is silent and smooth, and thus it is suitable for a factory that is located near a residential area. Reliability of the saddle has been improved also.


  1. Noise is reduced by approx. 5dB because there is no noise from flanged wheels.
  2. As wheels run smoothly and polyurethane absorb the vibration of the hoist, vibration conducted by the building will be reduced by approx. 50%.
  3. The guide roller is adopted, no noise from the flanged wheels and traveling is smooth.
  4. Terminal box that makes wiring simple is included.
  5. The middle shaft part of the driving side power transmission is unitized. Dismantling and assembling during installation are easy.
  6. Manufacturing time of the crane can be reduced by the centering mark for adjustment.
