The trolleybus had a self-supporting, steel body. A direct current DC motor is located between the axes. On the car body there was a wooden, lined protective strip run in the middle of the height of the side plating, also used in the first series of the successor - 8Tr. The floor height was 75 cm. The trolleybus had 3 doors. The wiper drive was pneumatic. The side windows were dropped. Electric heating was used.
The trolleybus was guided with 3 pedals. The right one was for semi-automatic, electro-pneumatic starting, middle for electrodynamic and pneumatic braking, and left for pneumatic braking. Sliding sanders are used on the rear axle to facilitate driving on slippery ground. The maximum speed was 50 km / h.
Electrical equipment was in front of the driver's cab. The self-starter was located on the right side of the electric chamber (looking in the direction of travel).
