CZK - TRAL (mechanický odmínovač)

Mechanical deminerTRAL is designed for mine clearance and rapid terrain reconnaissance. It creates a 70 cm wide tracked passage in the minefield in front of each tank track on which it is mounted. Anti-tank mines with rod fuzes are fed to detonate in front of the full width of the tank. With good visibility in soft terrain, two mechanical deminers can be used - TRALs going in steps behind each other so that the tracks of the carriages overlap, thus creating a wider track passage.
The TRAL can only be attached to tanks that have welded on rails and brackets for attaching the demining equipment. The TRAL, by its weight and the resistance of the trolleys to rolling on the ground, impairs the tank's driving characteristics, its ground clearance and manoeuvrability. It is preferably used on roads, on hard and drivable terrain. In wet and poorly bearing soils, in deep snow and in icy conditions, its driving characteristics and reliability are reduced.

The TRAL mechanical deminer can withstand mine blasts and explosive charges up to 10 kg explosive weight. If they are stored normally, it reliably detonates them. Mines laid deeper or with a booby-trap cannot be defused by mechanical deminers.

Data completion :

Mechanical deminer - tral ( hereafter MO-T) can be attached to tanks that are equipped with welded rails and brackets for attaching demining devices - T-54A, T-55.

The mechanical deminer - tral cannot be used on tanks T-34/85 and T-54A, which do not have these rails and mounts.
Mounting the MO-T on the tank and its dismounting can be done by the tank crew manually without a crane, It requires a well-trained crew and suitable flat and hard terrain. It takes 60 to 90 minutes. Dismantling takes 20 minutes. It is convenient to use a crane to assemble and disassemble the MO-T, the heaviest part of the trolley weighs 4600 kg.

It can be used in different terrain under different conditions and to defuse different types of anti-tank mines

It consists of two trolleys mounted on the main frame, which is suspended from the front of the tank. A roller is mounted on the front of the main frame which lifts the main frame in rough terrain and ensures that obstacles are overcome.

MO-T Main parts :
- 2 bogies,
- full suspension frame,
- main frame hitch,
- spacers.
Between the trolleys, a grid is hinged on the main frame, which feeds the explosion of the mine with rod fuzes.

The MO-T carriages travel continuously over the terrain and, by the weight of their armoured discs, bring both anti-tank (AT) and anti-personnel mines to detonation by pushing on their active parts.
Each carriage can withstand 5 explosions of PT mines with a 10 kg explosive charge or 15 explosions of PT mines with a 5 kg explosive charge.

Time required for : MO-T assembly (using crane) : 30 minutes / disassembly20 minutes

Dimensions of MO-T in mm:
Main frame length : 3200
Width of demining passage : 700
Trolley gauge : 2610 ( in working position)
Average road speed : 10 - 15 km/hr.
Max. Speed : when demining 10 km / h

Transportation :
- For shorter distances without dismounting,
- on a P-50 sleepers, even with a tank,
- over 50 km ( after dismounting) on trucks T-111, T-138, T-148 or by rail on Px, Pao series cars.
