This access platform is destined for lifting of persons and additional load only.

  • Page 28: Drive Control

    (see 6.1.2)! Transmission of the LEGUAN 135 is hydrostatic. Each wheel is equipped with a hydraulic motor - the machine is four wheel drive. If the machine is equipped with rubber tracks there are two hydraulic motors in the track system.

  • Page 29: Drive Speed Selection

    Drive and boom movements are equipped with electric ramps with which the movements start and stop (progressivity of acceleration and deceleration). The ramps can be adjusted by Leguan service at the service page of the remote-control. The ramps are intended to make starting and stopping of the movements smoother.

Rubber tracks are not designed for this kind of environments.

  • Page 33: Operation Of The Outriggers

    OPERATION OF THE OUTRIGGERS Lifting of the booms without setting down the outriggers is never allowed! When setting down the outriggers the maximum allowed inclination of the chassis is 1.5°. With automatic leveling it is possible to level the machine within one degree. With the water level it is possible to level the machine within 0.5°.
  • Page 34 The booms must be in transport position before driving the outriggers up! ATTENTION! If there is the text “Leveling OK” on the display when the outriggers are not correctly deployed, the operation of this access platform is not allowed! Contact nearest Leguan service!

    – in this case the telescopic boom is out more than one meter. LEGUAN 135 is also equipped with an overload control system which prevents boom movements in case the 230 kg safe working load is exceeded, or in case the telescopic boom comes out more than allowed when load on the platform is over 140 kg.

  • Page 36: Boom Deceleration

    10.1. Boom deceleration Boom movement speed can be slowed with the deceleration switch (see 6.1.1). The switch is equipped with four positions: full speed and three decelerations. The active deceleration mode is shown with the green LED above the switch. The blinking frequency of the LED indicates the progressivity of deceleration.

  • Page 37: Emergency Lowering

    EMERGENCY LOWERING If the power supply for some reason cuts off (e.g. no fuel or electricity cuts off, or connecting cable fails) the booms can be lowered as follows. 1. The lift is equipped with an electric emergency lowering system. There are emergency lowering buttons both on the platform and at ground level.

  • Page 38: Ending An Operation

    ENDING AN OPERATION When ending operation: 1. Lower the booms down to transport position. 2. Lift the outriggers completely up to transport position. 3. Stop the engine/motor with the remote-control start/stop switch. Turn off the remote control from its emergency stop switch. Lock the control unit in its place on the platform or take the unit with you.
