Electrical Jack Knife Bus Door System

Description Download
Electric folding door mechanism is the technology introduced by Japan, a new improved driving mechanism for opening/closing by the folding door of buses. The benefits are - compact structure, fine performance and long life service . It also has anti-clamp feature to overcome the seizure of cylinder piston rod movement to water condensation in cold areas. This electrical door mechanism is ideal for buses with no air supply & have foldable doors.

Ramp for Physically Challenged Passengers

Description Download
  • Easy access & egress for physically challenged passengers
  • Extremely robust and reliable construction.
  • Automatic stoppage of system in case if overloaded during retraction
  • Fully synchronized and interlocked with door system.
  • Reliable extension and retraction performance, controlled by electricity or pneumatic power.
  • Compact in size: The mechanism has the smallest thickness among the same products due to its unique articular driving system
  • Strength of vehicle frame not affected due to Ramp fitment
  • During operation, the movement of the ramp platform will be alarmed by chime and shining lamp
  • The Ramp Platform operation will be indicated by Audio-Visual alarm (Chime & glowing light indication.
  • The motor is protected against overload and overheat
  • Unique Anti- skid Ramp surface

Retractable Foot Step

Description Download
Rotex Retractable Foot Step is designed for high floor Buses. It is a new type of stepping structure with features such as Closeness to ground, safe, stable and reliable in service. It is installed on vehicle floor for passenger convenience. Step is retracted while bus is in motion. Control will be at drivers console and interfaced with door opening/closing A movable foot-step for a vehicle is operable by a mechanism including a guide device below the floor of the vehicle for extension of the step outside one side of the vehicle in an outwards/downwards movement and retraction in the opposite direction. The foot-step comprises a support structure over which an endless mat is stretched, and means for retaining a portion of the mat in the direction of movement of the foot-step, but not in the vertical direction.

Anti Pinch Sensor ( PDV)

Description Download
Whenever there is any obstruction at the door, due to the difference of air pressure in the cylinders, the mechanical switch operates and that signal is sensed by the controller thus making the door retract automatically.
