MS-20 Daglezja Towed Support Mobile Bridge, Poland

MS-20 Daglezja towed support mobile bridge

MS-20 Daglezja towed support mobile bridge, designed by OBRUM (Research and Development Centre for Mechanical Appliances), and manufactured by Bumar-Labedy, is in service with the Polish Armed Forces.

The bridge layer is designed to assist armed forces to move heavy vehicles, third-generation main battle tanks and 155mm self-propelled howitzers across water obstacles and trenches in combat operations. Civilian applications of the bridge include rescue, natural disaster assessment, crisis management and emergency response.

The MS-20 Daglezja was unveiled during the MSPO 2008 International Defence Industry Exhibition held in Kielce, Poland and also took part in the MSPO 2015.

Orders and deliveries of MS-20 Daglezja

The Polish Army intends to buy up to 50 MS-20 bridge layers to support its Leopard 2A5 main battle tanks. The first two MS-20 Daglezja bridges were delivered to the Polish Armament Inspectorate for use by the Polish Army in December 2012.

The Polish Armament Inspectorate accepted an offer to buy ten MS-20 bridge layers from OBRUM and Bumar-Labedy in February 2015.

MS-20 Daglezja design and features

The bridge is mounted on a high-mobility, all-wheel drive JELCZ C662D.43 6x6 truck-type tractor, attached with a 6x6 off-road semi-trailer, which has an additional hydraulic system. The truck's gross vehicle weight is 24,000kg and kerb weight is 14,500kg. It is operated by two personnel, seated in a two-door cabin.

The bridge layer is foldable and requires ten minutes to lie in a position. It is detached from the bridge when the span is distributed. It has a length of 42m with span complex put in place and of 16.5m with span on the saddle. It supports a mass of up to 47.9t and has a stand-by time of 30 minutes, whereas the roadway width is 4m.

The mobile bridge allows tracked or wheeled military vehicles to cross obstacles of width up to 20m. It can withstand loads of military load classification (MLC) 70 for tracked vehicle and up to MLC 110 for wheeled vehicles in STANAG 2021 standard.

Standard equipment aboard the truck includes a 100kN hydraulic winch, a hatch on the roof, an air conditioning system, an air heating system, a filter-ventilating device, and a water heating system. The vehicle can be optionally fitted with a search lamp, variable function insert, and orange flasher lamp.

Drivetrain of the mobile bridge

The truck is driven by IVECO FPT Cursor 10 EURO III, a four-stroke, inline six-cylinder, intercooled, turbocharged diesel engine that develops a maximum power of 316kW at 2,100rpm and a maximum torque of 1,900nm at 1,050rpm-1,590rpm. The engine is coupled to a 16-speed, mechanical ZF 16S 221 gearbox.

"The mobile bridge allows tracked or wheeled military vehicles to cross obstacles of width up to 20m."

The 14.00 R20 tyres, featuring central tyre inflation system and beadlock inserts, deliver increased mobility on off-road conditions.

The front suspension consists of differential lock combined on two half-elliptic springs with rocking levers and two telescopic shock absorbers. The rear suspension is mounted on the frame by reaction rods with two inverted half-elliptic leaf springs. It also has inter-axle and wheel differential locks.

JELCZ C662D.43 performance

The JELCZ C662D.43 tractor with bridge layer onboard can reach a maximum speed of 85km/h on roads. It can climb vertical obstacles of 0.3m, cross ditches of 0.6m and overcome deep water obstacles of 1.2m.

The maximum height on both sides of the obstacle is 2m and the maximum slope is 5%.

The bridge offers high mobility and can withstand temperatures ranging between -30°C to 50°C.
