RAMTA Track Width Mine Plough (TWMP)
Date Posted: 18 September 2002
The RAMTA Track Width Mine Plough (TWMP) can be fitted to all types of modern MBT in use. The TWMP has been fitted to Centurion, M48, M60, M1 and M1A1 Abrams, Leopard 1, Leopard 2 and Merkava MBTs.
In January 1989, it was announced that the US Army had ordered more than 400 RAMTA TWMPs, known to the US Army as the Mine Clearance Blade System (MCBS). The MCBS was operated by the Allied forces during Operation Desert Storm in the Persian Gulf.
The RAMTA TWMP consists of two plough units with separate lifting mechanisms and depth control systems. No alterations to the tank are needed as the plough is attached to the towing lugs on the tank front hull. Transferring the TWMP from one tank to another takes less than 1 hour using the tool kit supplied.
The TWMP is operated by the tank driver. When travelling, the ploughs are raised and secured by a locking device. In operation, the driver releases the locking device and the ploughs drop free for the teeth to dig into the ground and dislodge buried mines which are then pushed aside. Any tilt-rod mines in the central unploughed area between the ploughs, will be detonated by a chain suspended between the ploughs. Each plough unit operates independently and follows the natural terrain contours, clearing a path wider than the tank tracks.
After use, the TWMP can be lifted back to the travelling position by a mechanical device connected to the track tension wheel or by 24 V DC electrical motors.

RAMTA Anti-Magnetic Mine-Actuating Devices (AMMAD)
Date Posted: 16 August 2002
RAMTA's Anti-Magnetic Mine Actuating Devices (AMMAD) are intended to actuate magnetic influence fuzed mines before a carrier vehicle reaches them. The AMMAD operates by projecting a fluctuating magnetic field some 3 to 5 m ahead of the carrier vehicle. Magnetic influence fuzed mines detect the magnetic field change and interpret it as a target vehicle.
Two versions are available. One, the OnBoard AMMAD (OB AMMAD), consists of two magnetic field emitter units carried on the front hull of a tank; a control panel is mounted in the driver's compartment. The AMMAD does not interfere with other onboard systems and has a power consumption of less than 20 A at 24 V. System weight is approximately 113 kg.
The second version, the Rolling AMMAD, is a roller device slung between mineclearing ploughs or rollers, and is also known as the Improved Dogbone Assembly (IDA). It may be used as a stand-alone or an add-on kit. This version operates by generating a magnetic field as a result of its rolling motion on the ground. Removal and installation are simple and do not require any special skills. The mobility of the carrier tank is not affected by the Roller AMMAD.
In production. OB AMMAD is in service with the Israel Defence Force, Italian Army, Swedish Army, Swiss Army, US Army and Marine Corps and various other customers. More than 1,000 AMMAD systems were delivered to the US Army and Marine Corps. Some were deployed during Operations Desert Shield and Desert Storm.

RAMTA Track Width Mine Plough (TWMP)
Date Posted: 18 September 2002
The RAMTA Track Width Mine Plough (TWMP) can be fitted to all types of modern MBT in use. The TWMP has been fitted to Centurion, M48, M60, M1 and M1A1 Abrams, Leopard 1, Leopard 2 and Merkava MBTs. ...
The Track Width Mine Plough (TWMP) is produced by RAMTA Aerostructures and Systems Division of Israeli Aircraft Industries Ltd. The plough consists of 2 plough units with separate lifting mechanisms and depth control systems. Each unit operates independently and follows the terrain contours, clearing a path winder than the tank tracks. It can be transferred from one tank to another within one hour.
Ordered by the US Army in 1989 and operated by the Allied forces during Operation Desert Storm in the Persian Gulf.
3 ploughs were acquired and sent to the Danish C-squadron in Bosnia-Herzegovina in the mid 1990´s.
The Track Width Mine Plough unit (TWMP) was designed and built by RAMTA, a division of Israel Aircraft Industries, and allows the clearance of anti- personnel and anti-tank mines from the path of the tank tracks. The plough action moves the mines aside without detonating them, and can be adjusted to give a clearance depth of 200, 250 or 300 mm. The TWMP clears a lane about one metre wide in front of each track, and there is an unploughed lane 1500 mm wide between the tracks. In this uncleared area, the TWMP drags a “dog bone” which is used to detonate tilt rod mines. The total weight of the installed equipment is around 3 tonnes.
The TWMP comprises a main frame, which is attached to the tank in a similar manner to the dozer attachment. Push beams provide support to the ploughs, known as moldboards. Skids are located on the push beams to regulate the plough depth. Lifting mechanisms allow the left and right moldboards to be raised and lowered independently. An electrical harness, feeding though the armoured conduit cover, connects with the control box in the driver’s compartment. This provides the driver with the means of operating the TWMP and also allows him to fire the quick disconnect cartridges, which allows the whole assembly to be jettisoned in case of damage.
When originally purchased, the TWMPs were painted in Israeli sand colour, and some of the photos show this. Interestingly, the RAMTA company is located at Beer-Sheva in Israel, better known in Australia as Beersheba, the location of the most famous of Light Horse actions during the First World War.
One known experiment with the TWMP was soon after its introduction, when the Technical Squadron of 1st Armoured Regiment constructed a device to fit the TWMP allowing the clearance of scatterable mines. Although tested at the then Armoured Centre, it is believed to have been a unit experiment only. Two TWMPs are in service with the 1st Armoured Regiment and one with the Mounted Combat Division.
The Mine Clearance Roller System comprises a set of two roller banks, attached to the front of an MBT, designed to detonate mines in the path of the tank tracks. It is manufactured by Urdan Industries Ltd of Israel. The design is very similar to former Soviet mine roller systems.
Each roller bank rolls a width of approximately 1100 mm and there is an unrolled area of approximately 1500 mm between the rollers. Mines buried up to 100mm deep can be exploded. The total weight of the installed equipment is 9 tonnes.
The MCRS comprises a number of assemblies. An adaptor plate is mounted onto the hull of the tank in a similar way to the dozer and TWMP systems, using the hull rails and the towing lugs. The adaptor plate mounts several brackets and tie rods. The roller bank push arms are attached to the adaptor plate brackets. The roller bank push arms have integral rubber buffers which allow deflection of the arms, via the pivot when attached to the brackets of the adaptor, which can rise and touch the adaptor during mine explosions.
The roller bank assemblies have four cast steel rollers, the outside two of which are mounted on bearings, and the inside pair which have a larger internal diameter and are free to move around the axle shaft. The roller bank is attached to a pusharm via chains and trunnions.
Cable assemblies support the pusharms during normal travel and absorb some shock during mine explosions. A dog-bone assembly is hung between the two roller banks in order to detonate tilt rod mines.
The MCRS is a large and cumbersome device when fitted to the Leopard, and makes driving and steering somewhat sluggish. Their worth to mounted operations however, outweighs these factors, and their use by many armies around the world is proof of their effectiveness when dealing with minefields on the modern battlefield.
