Light Weight Mine Roller
The Light Weight Mine Roller (LWMR) protects vehicles from buried mines and pressure initiated explosive devices by using roller gangs, which follow the ground over undulating terrain, to apply pressure to the ground ahead of the host vehicle to detonate a threat before the vehicle and its crew reaches them. The LWMR gives track width protection.
The system is generally used where there is a possibility, rather than the probability of the presence of threats on an intended route.
The product is battle proven and is in service with, amongst others, the U.S. Army and the Canadian Armed Forces.
The LWMR comprises two 4-wheel roller gangs to protect the vehicle tracks. The wheel tyres are puncture proof and are made from a special wear resistant semi-compliant polyurethane compound.
The system is lightweight yet generates a heavy effect using hydraulic power to transfer a proportion of the vehicle weight onto the roller wheels to generate the required pushdown force to detonate any explosive devices. This hydraulic design avoids the requirement for self-weight roller wheels which add unnecessary weight to the host vehicle.
The LWMR can be fitted using a common interface kit which allows the task equipment to be quickly and easily interchanged and jettisoned increasing the operational capability of the host vehicle.
- Light weight but heavy effect
- Minimal effect on vehicle mobility and manoeuvrability
- Roller wheels follow ground contours providing constant ground contact and can be fully raised into a transport position when not in use
- Solid tyres resist punctures and damage
- Rapidly repairable
- Available in Track Width or Full Width configurations
- Can be fitted to both Medium Tracked and Wheeled Combat Vehicles with minimal modification
- A robust and compact system which requires little maintenance
- Can be fitted with a MSD to counter magnetic influence fused mines.
A LWMR has three operating positions; stowed for cross-country travel, pushdown for rolling and float for maintenance purposes.
A hydraulic lift cylinder stows and deploys the LWMR. Hydraulic power is provided by an in-built electrohydraulic power system if a LWMR is fitted directly to a vehicle, or from an on-board hydraulic system that can be provided as part of a Pearson Engineering Common Interface System.
A LWMR is controlled from a Mission Equipment Control Unit (MECU) mounted within easy reach of the vehicle driver.
An optional steering system can articulate the LWMR right and left in response to MECU commands.
The LWMR can be rapidly attached to or detached from the vehicle and interchanged with other Special to Role equipment.
Typically Track Width for vehicle self-protection, the LWMR can be upgraded to a Full Width system by adding a Rear Roller Kit (RRK) (a single set of six individually articulating wheels), providing protection for following vehicles. Steering input commands from the RRK may also be used to automatically control the steering position of the front mounted LWMR.
An optional Magnetic System Duplicator (MSD) can be fitted to help protect the equipment from the effect of magnetic influence fused mines.
A purpose built Transportation Pallet facilitates both storage and transportation and is capable of fitting into either an ISO container or onto a DROPS pallet.
