Oshkosh pls

In 1989, the US Army Tank Automotive Command (now the TACOM Life Cycle Management Command) entered into contracts for prototyping the PLS system with Oshkosh Truck Corporation , PACCAR and General Motors . Oshkosh PLS offered an unusual 5-axis configuration with two first and last controlled axles, which allowed to fit into the requirements for maneuverability, maneuverability and axle load. Competitors offered 4-axis configurations: Paccar - with three axles behind, General Motors - Americanized version of the truck MAN KAT1 (8 × 8).

According to the results of testing, which began in September 1989, Oshkosh Truck Corporation received a five-year contract for PLS in September 1990, having launched mass production in 1992. In December 2009, the last of the 6288 PLS ordered variants A0 were delivered.

Because The US Marine Corps does not use HEMTT trucks and the PLS system, then in 1998, together with several cargo manufacturers, an ATD (demonstrator) (Advanced Technology Demonstrator) was created, after testing and analyzing alternatives, the Logistics Management Institute in 2001 developed recommendations for replacing the existing The LVS (Logistics Vehicle System) fleet, also based on the 4-axis “C platform” (like the HEMTT). In March 2004, 3 test trucks were delivered as the first part of a two-phase tender for the final selection of one of 2 suppliers (in addition to Oshkosh it was American Truck Company). The first phase consisted of field trials, which ended in 2005, and only in 2006 did the USMC sign a contract for $ 28 million (22 trucks, 2 repair and recovery vehicles and a truck tractor, spare parts, personnel training and support for the duration of the test). Tests of trucks began at the Aberdeen Proving Ground test site in June 2007, the tow truck in November 2007, and evacuation vehicles in April 2008. The next 123 trucks as part of the low-rate initial production ( LRIP ) were delivered two years. In January 2009, Oshkosh announced the delivery of 425 LVSR worth $ 176 million as "part of the transition to full-scale production (FRP). They were first applied in Afghanistan in September 2009.

By the middle of 2013, over 2,150 PLS A1 and 15,000 trailers were delivered.

By September 2013, a total of 1,505 multi-lift trucks (MKR18), 355 MKR16 truck tractors and 162 MKR15 recovery vehicles were delivered under the LVSR program.

Since October 2008, PLS A1 cars are being manufactured with an anti-lock system , an improved electrical system, a new, more spacious cabin (common to the entire Family of Heavy Tactical Vehicles (FHTV), including HEMTT, LVSR and HETS) , a regular place for the installation of a machine gun, booking a machine gun point, the floor of the cab and places that are difficult to install mounted armor in the field (so-called "A-kit"), with the possibility of gaining outboard booking in the field using so-called "Set B" ("B-kit").

From June 2015 to May 2018, 4 contracts for renovation of 4092 PLS A0 in total to level A1 were signed - with a complete reassembly of all units to the “as new” state, passing the same tests as for new cars and the corresponding warranty update.

On June 27, 2018, the US Army Automotive Research, Development and Engineering Center (TARDEC) contracted $ 49 million to integrate existing PLS trucks with a so-called. Expedient Leader Follower (ExLF) —scalable autonomous technologies — to remove soldiers from a vehicle while working in areas with a high degree of danger (70 sets are expected to be supplied with an option for another 150). It uses the TerraMax complex - developed by Oshkosh Defense in the framework of the DARPA Grand Challenges 2004-2005 and DARPA Urban Challenge 2007 programs - unmanned vehicle control in different modes (by the operator, autonomously, in the “following the leader” mode - up to 5 cars in one convoy).

PLS system includes:

• 2 truck options: M1074 with a multi-lift - for loading / unloading and transporting pallets on standardized Flatrack loading platforms, ISO containers without loading onto Flatrack platforms (when installing the Container Handling Unit (CHU) kit, weighing 1476 kg and mobile modules), and M1075 with a manipulator (crane)

• the Flatrack platforms proper : M1077 / M1077A1 - “Type A” (without boards); M3 / M3A1 - with rollers of the CROP system (Roll-in / Out Platform) for easy loading / unloading and transportation of a 20-foot container ; " M1" - ISO-compatible, with 2 drop sides in front and behind, several pieces are incorporated in "type A "
• three-axle trailer M1076 (in fact - trolleys) for the transport of goods with a total weight of up to 16.5 US tons (15,000 kg) on ​​Flatrack platforms; without leaving the cab, using a multi-lift or manipulator, the driver can load and unload a truck in less than one minute, and a truck with a trailer in less than five minutes;
• EMM engineering modules hosted on Flatrack platforms and connected to the power grid of the truck using the Universal Power Interface Kit ( UPIK ); include bitumen tanks with EMM-BD ( M4 Bituminous Distributor) bitumen feeding and filling devices, EMM-CMM ( M5 Concrete Mobile Mixer) blended concrete mixer, and M6 - demountable dump body ( EMM-DB ).

Flatracks platforms, CHU / E-CHU kits, as well as Modular Fuel System (MFS) fuel tanks and Hippo tankracks - for water, - PLS and HEMTT-LHS systems are interchangeable.

The PLS-Enhanced program (PLS-E) includes the installation of a tactical wheeled vehicle tracking system based on a global positioning system and the possibility of two-way digital messaging through the Movement Tracking System (MTS) using both military and commercial satellite communications systems as well as DVE (driver vision enhancer) thermal imaging system. DVE allows you to see a 22-inch (0.55 m) object at more than 100 m in smoke, fog, sandstorm at night, which ensures an average speed of movement of at least 60% of that under conditions of day visibility. The imager can be raised at an angle of 35 degrees, lowered by 5, and can be rotated 170 degrees in both directions.

MTS allows the commander to track the entire logistics chain at the tactical level and to quickly redirect cargoes in accordance with the needs of the service units.

The LVSR system includes: MKR15 - repair and recovery vehicle, MKR16 - truck tractor, MKR18 - truck with multi-lift. Used in common with PLS platforms flatrack and universal trailers M1076. The MKR15 is capable of towing vehicles weighing up to 110,000 pounds (49,900 kg), with partial loading of 96,000 pounds (43,546 kg), completed with a back winch with a force of 35,780 kg and a front winch with a force of 9.072 kg. MKR16 equipped with a front winch force of 60,000 lb. (27216 kg).

LVSR trucks are equipped with Oshkosh's Command Zone ™ multiplex monitoring and self-diagnosis system.

In general, trucks have a large number of components and parts interchangeable with a family of medium-sized (5-9 tons of payload, 8x8 LHS - up to 15) MTVR trucks: wheels, TAK-4 suspension, front axles, power supplies, control, etc.

The base of the chassis is a powerful spar frame made of profiles 356 × 89 × 9.5 mm, steel SAE1027 (heat-treated carbon manganese) with a tensile strength of 758 MPa .

On variant A0 - the diesel engine of the company Detroit Diesel 92T A-90 (8V92TA), two-stroke, V-shaped, 8-cylinder with turbocharging and intermediate air cooler. Working volume is 12,1 l, power is 500 l. with. Torque - 1900 N · m at 1000—1800 rpm. The area of ​​the cooling radiator is 13,000 cm².

The A1 variant is a four-stroke Caterpillar C-15 inline 6-cylinder, 15.2 liters of volume, 600 hp. at 1800min-¹, 2508 Nm at 1200 min-¹.

Permanent all-wheel drive 10 × 10. Transmission automatic hydromechanical Allison 4500SP, 6-speed, interlocked with a two-stage razdatkoy Oshkosh 36 000 Series. The hydrodynamic retarder with a capacity of 450 liters is integrated into the transmission. with. There is a power take-off shaft .

A 5-speed automatic hydromechanical gearbox was installed on PLS A0 (until October 2005)
