TK-EKT58

Large Electric Passenger Stairs

The TK-EKT58 is a high-reach, fully electric, self-propelled passenger boarding stair designed for aircraft door heights from 2,150 to 5,800 mm across regional, narrow-body and wide-body fleets.

Its 1,500 mm clear stairway and platform options up to 3,640 × 2,820 mm support efficient passenger flow. A purpose-built low-center-of-gravity chassis, six hydraulic stabilizers and an auxiliary safe-docking system provide stable operation at height, precise final approach and automatic braking near the aircraft.

Features

Extended Boarding Height Range
The 2,150–5,800 mm working range supports passenger boarding across regional, narrow-body and wide-body aircraft.

Full-Electric Drive System
A 65 kW permanent-magnet motor and 81.14 kWh LFP battery support efficient, low-emission apron operation.

Safe Aircraft Docking
Distance sensing, controlled low-speed approach, automatic braking and anti-collision protection support safe and accurate aircraft docking.

Safety Interlocks
Travel, charging, stabilizer deployment, and stair operations are electronically interlocked to prevent unsafe vehicle movement.

Structural Stability 
A purpose-built low-center-of-gravity chassis, wide-track axles, six hydraulic stabilizers and dual locking support stable elevated operation. 

Passenger Safety & Flow 
A 1,500 mm clear stairway, anti-slip aluminum treads, illuminated handrails and a large platform support safe, efficient boarding. 

Operator Control & Monitoring 
CAN-bus controls, integrated status displays, and warning systems provide clear operating information and simplified fault monitoring. 

Emergency Operation 
Emergency electric and manual pumps, manual retraction controls and towing points allow rapid aircraft clearance following a system failure.
