   The self-propelled ladder TG-1841 has been specially designed to carry out the loading/offloading of aircraft passengers; the vehicle's threshold in the loading/offloading doors is a height above ground of between 1.80 m (70.8") and 4.10 m (161.3").
   The ladder is a compact self-propelled vehicle comprising a frame with two flights of steps, one fixed and the other mobile, which slides telescopically over the fixed flight propelled by a hydraulic cylinder. In the upper part of the mobile flight there is a platform with tip-up front to adapt it to the aircraft's profile on the loading/offloading door's lower threshold. On each side of the platform there is an ear which is automatically adjusted to fit over the sides of the aircraft's door.
   The loading/offloading platform can be situated at a height of between 1.80 m (70.8"), in its lowest position, and 4.10 m (161.3"), in its highest position. The loading/offloading platform and the flight of steps are protected by railings. The power unit is located in the centre of the chassis and below the fixed flight of steps. It comprises a diesel engine which activates a variable displacement hydraulic pump to power the traction circuit and the accessories circuit.
   The ladder is fitted with front and rear self-levelling hydraulic stabilizer jacks.
   In the event of faults, the unit is equipped with
a manually activated hydraulic pump for unlock- ing the ladder's cylinders as well as safety devices so that it can be pulled away from the aircraft by hand.
   The passenger ladder described in this Manual has been designed in compliance with IATA (AHM920) and SAE (ARP836.A) specifications and meets the requirements of EN 12312-1.

ENGINE: Deutz Diesel model D2008L4, air-cooled, 4 cylinders with a diameter/stroke of 76/86 mm, 1.56 litre cylinder capacity, power 27 kW/3000 rpm, maximum torque 92 Nm at 2000 rpm.

TRANSMISSION: Hydrostatic with automotive variable displace- ment pump, which powers two wheel travel motors. Mounted in tandem with the hydraulic travel pump is another pump which powers the steering Orbitrol, the stabilizer jacks and the ladder's telescopic system.
