Light Weight Proofing Roller
The Light Weight Proofing Roller (LWPR) 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 threats before the vehicle and its crew reaches them.
The LWPR gives full 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 LWPR comprises two 6-wheel roller gangs to protect the vehicle tracks and a central 5-wheel roller gang to provide full width clearance for following operations.
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 system is generally used where there is the possibility, rather than the probability of the presence of threats on an intended route.
The LWPR 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
- Can be fitted to Heavy Tracked 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 LWPR has three operating positions; stowed for cross-country travel, push-down for rolling and float for maintenance purposes. A hydraulic lift cylinder stows and deploys the LWPR.
Hydraulic power is provided by an in-built electrohydraulic power system if a LWPR(H) 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 LWPR is controlled from a Multipurpose Control Unit (MCU) mounted within easy reach of the vehicle driver.
A steering system can articulate the LWPR right and left in response to MCU commands.
The LWPR can be rapidly attached to or detached from the vehicle and interchanged with other Special to Role equipment.
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.
