Salvage tank type 70




Development


The development of the Japanese Type 70 recovery tank began in 1957, and was essentially concurrent with the development of the Type 61 medium tank, which it was intended to provide technically for tank units and from whose machine underpinnings it was based. The development and subsequent production was entrusted to Maruko - Mitsubishi Heavy Industries. Serial production began in 1959, and a year later in 1960 the tank was introduced into the armament of the Japanese Self-Defense Forces. The Type 70 salvage tank is the oldest type of salvage tank in the Japanese Armed Forces. It is being replaced by the more modern Type 78 recovery vehicle.




Designation


The Type 70 recovery tank was intended for technical support of Japanese armoured units armed with Type 61 medium tanks, for recovery and removal of stranded or damaged equipment from the battlefield, and for light and medium repair of combat equipment in the field. It could also be used to remove roadblocks from roads and, exceptionally, to dig trenches for combat equipment.




Description


The Type 70 ARV salvage tank was based on the Type 61 medium tank. The driver's station, like that of the Type 61, was located at the right front of the hull, just in front of the crew compartment. The driver's hatch was one-piece and hinged towards the right side. When driving in the combat position, the driver used three periscopes located in front of the hatch in the armour.
The original turret set was removed. The sloping frontal armour transitioned at the top into a horizontal hull ceiling that extended the full length of the tank. Subsequent modification of the sides and ceiling of the hull created a transport space for a crew of four men (commander, driver and two mechanics). The hull and the crew compartment were welded from armoured plates. In the rear of the hull was the engine compartment. On both sides of the crew compartment were attached the arms of a frame hoist, which in the transport position was placed on a support frame above the engine compartment of the vehicle. The support frame could also serve as a weighing device for the damaged equipment. In the working position, the frame jack was raised above the front of the vehicle. The exhausts were located on the fenders, above the fourth and fifth running wheels on either side of the hull.

The hull and carriage compartment provided protection for the crew against infantry gun shots and artillery shell fragments.




Chassis, engine and transmission



The tank's chassis consisted of six running wheels on either side of the hull, suspended by torsion bars. The first, second, fifth and sixth running wheels on either side of the hull were equipped with hydraulic shock absorbers. The drive wheel was at the front and the tensioning wheel at the rear. The upper branch of the running gear consisted of three supporting pulleys on both sides of the hull. The track was 500 mm wide. The length of the contact area between the track and the ground was 3 700 mm.


The tank was powered by a 12-cylinder four-stroke diesel engine, turbocharged with direct fuel injection Mitsubishi Type 12 HM 21 WT (V-12) with a power of 447 kW at 2 100 rpm. The engine had relatively high fuel consumption, which reduced the tank's range to only 200 km on the road.


The Type 70 ARV tank had a gearbox located in the front of the hull on the left side of the driver. This method of mounting the transmission proved to be another weakness of the tank. The torque transfer between the engine and transmission was provided by the drive shaft, which was mounted across the hull of the vehicle and therefore the crew compartment. This resulted in a relatively large loss of space inside the vehicle. Consequently, the maintenance or eventual replacement of the damaged shaft was difficult and complicated.


The transmission of torque from the engine to the chassis was provided by a mechanical gearbox with 5 forward and 1 reverse gear.




Armament and ammunition


The main armament of the tank consisted of the Type 60 mortar of 81 mm calibre, designed to destroy live forces and lightly armoured enemy vehicles.
The tank's additional armament consisted of a 12.7 mm M2HB anti-aircraft machine gun, mounted next to the commander's hatch on the ceiling of the crew compartment, designed to destroy enemy live fire and low-flying targets. The firepower carried was 525 rounds of 12.7 mm calibre ammunition.




Crew survival systems


The tank was not equipped with a WMD filtering device and therefore the crew had to use individual protection devices. The vehicle was not equipped with fire-fighting equipment. The driver could replace the medium periscope at his station with an active infrared periscope. Without preparation, the tank could wade to a depth of 1.0 m.




Special equipment


A hydraulically operated dozer blade was mounted at the front of the hull to anchor the vehicle when working with a winch or crane boom. Exceptionally, it could also be used for light field work and digging trenches for equipment.
- The maximum working capacity of the plough is 110 m3/h
- the width of the coulter is 2 700 mm
- plough height is 400 mm


The mechanically operated frame hoist was taught to replace groups and sub-groups in field conditions. With its parameters it was able to perform the same tasks on the Type -61 tank.


The main winch was intended for recovery of trapped or damaged equipment, or for removal of obstacles from roads, self-clearing, etc. It was located at the rear of the vehicle hull.


The vehicle is also equipped with.
- a set of towing bars (triangles),
- a set of rescue equipment and tools,
- a set of winch pulleys,
- a set of engineer tools
