Trident Miniatures 1:87 Military - 81010
Made in Austria

The Herpa Military series includes a large number of high-quality finished models from the field of military vehicles and aircraft as printed and unprinted versions. The technology of vehicles and aircraft from the time of the First World War to the present day fascinates collectors and diorama builders alike. The series is constantly being expanded with new forms and printing variants.



TThe Palletized Load System (PLS) is based around two variants of prime mover truck (M1074 and M1075) fitted with an integral self-loading and unloading capability, a trailer (M1076), and demountable cargo beds, referred to as flatracks. PLS trucks and trailers are air-transportable in C-5A and C-17 cargo aircraft.

Truck

The PLS prime mover truck carries its payloads on its demountable flatrack cargo beds, or inside 8×8×20 foot International Organization for Standardization (ISO) intermodal containers, or shelters. The M1074 is equipped with a variable reach material handling crane (MHC), the M1075 is not. A dp Manufacturing PLS-22K self-recovery winch with a capacity of 9,072 kg is an option on both the M1074 and M1075.

The Oshkosh PLS truck is based on a C-section chassis formed of 356 × 89 × 9.5 mm SAE 1027 modified heat-treated carbon manganese steel with a yield strength of 758 Mpa. Bolted construction with Grade 8 bolts is used throughout. PLS is unusual in that it is a five-axle truck, with two front and three rear axles, and with steering on the rear (5th) and front axle pair. A five-axle (10 × 10) configuration was selected by Oshkosh as it provides optimum turning capability and good weight distribution between all axles providing mobility and capability above the desired level of the U.S. Army specification. Competing PLS designs were both four-axle (8x8s), the Paccar offering having a single front axle and rear tridem, the General Motors offering was an Americanised MAN KAT1 (8×8).

Current PLS A1 variants are powered by a Caterpillar C-15 four-stroke diesel developing 600 hp, this coupled to an Allison 4500SP six-speed automatic transmission, and Oshkosh 36000 Series two-speed transfer case.[2] The original PLS was powered by a Detroit Diesel 8V92TA V-8 two-stroke diesel developing 500 hp, with later production examples having the electronically-controlled DDECIV version of this engine. Original PLS were fitted with an Allison CLT-755 ATEC 5F/1R automatic transmission and Oshkosh 55000 two-speed transfer box. After October 2005, an Allison HD-4500 Generation 4 six-speed automatic transmission was fitted.

All PLS variants have the same rear tridem unit which consists of a single Hendrickson-Turner air-sprung drive axle (3rd axle) and a Hendrickson RT-400 leaf-sprung AxleTech tandem (4th and 5th axles) on which the rearmost axle contra-steers.[2] On PLS A1 variants the front AxleTech/Oshkosh axles are sprung using Oshkosh's TAK-4 fully independent coil spring suspension. The original PLS had a pair of rigid AxleTech front axles, these with leaf springs.

Tires are Michelin 1600R 20. Current fit is Michelin XZL, earlier PLS were fitted Michelin XL. A central tire inflation system (CTIS) is fitted, this having four settings - HWY (highway) • CC (cross-country) • MSS (mud sand snow) • EMERG (emergency). A spare wheel and tire is mounted behind the cab on A0 variants. On A1 variants the spare wheel and tire is located on the right-hand side of the vehicle, on the top of the engine/cooling compartments.

The two-seat forward control cab is a development of the original Oshkosh M977 HEMTT cab. The PLS A1 (and HEMTT A4)has a visually similar, but slightly larger, revised cab. An add-on armor kit has been developed for the M1074/M1075 by Armor Holdings Inc. PLS A1's cab is compliant with the U.S. Army's Long Term Armor Strategy (LTAS) requirements of an A- and B-kit armoring philosophy. Additionally, it comes as standard with integrated floor armor.

About Trident Miniatures

Trident, whose products are imported from Austria by Walthers, was founded in 1966. Their goal was to provide collectors with accurate replicas of prototype vehicles through the use of extensive research, photos and, when possible, original blueprints. Trident offers a wide variety of 1/87 model kits featuring plastic and white-metal parts, as well as a line of military decals.
