COMMERCIAL ITEM DESCRIPTION

MOBILIZER, DOLLY SET, 12-TON

The General Services Administration has authorized the use of this Commercial Item Description for all federal agencies.

1. SCOPE.

1.1 Scope. This commercial item description (CID) describes a battery powered, dolly set mobilizer that is capable of lifting, loading, and transporting an International Standard Organization (ISO) container or shelter with a payload of up to 12 U.S. tons (24,000 lbs.). The mobilizer consists of a front-steerable dolly and a rear-trailer dolly with interconnecting brake lines and electrical harnesses that can be towed across all surfaces, including primary roads, secondary roads, and cross-country terrain. Each dolly half is equipped with a battery-powered, hydraulic lift system, which allows the mobilizer to act as a shelter-handling device for lifting and loading on vehicles and aircraft. The mobilizer can be towed by any tactical vehicle that can meet the appropriate towing capacity and connections of the mobilizer. The system is designed to be loaded onto a C-5, C-17, and C-130 aircraft using its own power and the aircraft winch.

The mobilizer shall be compatible with any tactical vehicle with a 5-ton or higher rating and a pintle hook assembly. The mobilizer shall travel on primary roads and secondary roads, and shall be air transportable. The mobilizer shall be able to attach to a shelter, lift for transport, secure in transport mode, and return the shelter to its uncoupled and original configuration.

2.2 Design and construction. The design shall promote cost effective, life-cycle sustainability by addressing considerations such as incorporating open standards, reducing pollutant emissions and wastes, while satisfying system performance requirements. It shall be designed and constructed so that no parts will work loose in service, and to withstand the strains, jars, vibrations, and other conditions incident to shipping, storage, installation, and service. It shall be weatherproof and designed to prevent the intrusion of water, sand, and dust into critical operating components. The mobilizer shall include a one year manufacturer’s warranty.

2.2.1 Materials, protective coatings, and finish.

2.2.1.1 Protective coatings. Materials that deteriorate when exposed to sunlight, weather, or operational conditions normally encountered during the service life of the item shall not be used or shall have means of protection against such deterioration that does not prevent compliance with the performance requirements specified herein. Protective coatings that chip, crack, or scale with age or extremes of climatic conditions or when exposed to heat shall not be used. Exposed surfaces of fasteners, handles, and fittings shall also be primed and painted. Prior to painting, metal materials shall be coated with a Chemical Agent Resistant Coating (CARC) system in accordance with MIL-DTL-53072, and aluminum and aluminum alloys shall be coated with a Chemical Conversion Coating in accordance with MIL-DTL-5541, Class 3.
