T-54/T-55 fitted with BTU dozer blade for clearing soil, obstacles and snow in combat situations.
It was used by the tank units requiring specialized engineer support.
The dozer blade itself can mounted in 1 hour and 30 minutes and dismounted in 1 hour.
In the west it is known as T-54/T-55 Dozer.

ALT-55 – T-55 converted into an armoured tracked bulldozer.
It has a large flat-plate superstructure, angular concave dozer blade mounted in the front and hydraulic rams for the dozer blade.

T-55 converted into a tracked armoured excavator.
The turret has been replaced by a rotatable armoured cab with a boom and a bucket.
A dozer blade is fitted to front of the hull.

T-55 MARRS – T-55 converted into an engineering vehicle fitted with the MARRS Vickers armoured recovery vehicle kit.
The turret has been replaced by a new one, large flat-plate with slightly chamfered sides, vertical rear and very chmfered front and a large A-frame crane mounted in the front.
The crane has cylindrical winch rope feer between legs of the crane.
A dozer blade is fitted to the hull front.

IMR (Ob'yekt 616) (IMR stands for Inzhenernaya Mashina Razgrazhdeniya) – T-55 converted into a combat engineer vehicle.
The turret was replaced with a hydraulically operated crane with capacity of 2 tonnes, capable of 360° turn.
The crane is operated from an armoured cupola with a visor can also be fitted with a small bucket and used as excavator arm or a pair of pincer type grabs for removing obstacles like trees.
Its jib is telescopic and when in traveling position it is folded down and placed on a cradle in the rear of the hull which is folded down against the engine deck when the crane is in use.
A hydraulically operated dozer blade is mounted to the front of the hull; it can be used in a straight or V-configuration only.
The vehicle is fitted with a searchlight.
The IMR was developed in 1969 and entered service five years later.

SPK-12G (SPK stands for Samokhodniy Pod’yomniy Kran) – Heavy crane mounted on T-55 chassis.
Only two were built.

MTP-3 (MTP stands for Mashina Tekhnicheskoj Pomoshchi) – SU-122-54 converted into a technical support vehicle fitted with a light crane.
This conversion was carried out beginning in 1973.
It is sometimes known in the West as ARV M1977 and T-62T.
