COMMERCIAL ITEM DESCRIPTION

DOLLY SET MOBILIZER, 7-1/2 TON

The General Services Administration has authorized the use of this commercial item description (CID) for all federal agencies.

1. SCOPE. This CID describes a dolly set mobilizer that is capable of lifting, loading, and transporting an International Standard Organization (ISO) container or shelter with a payload of 7-1/2 U.S. tons (15,000 lbs) and has an overload capacity of 10 U.S. tons (20,000 lbs), to be carried for a limited amount of time. 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. Each dolly half is equipped with a diesel-powered, hydraulic lift system, which allows the mobilizer to act as a shelter-handling device for lifting, and truck or aircraft loading. 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-130, C-17, and C-5 aircraft using its own power and the aircraft winch.

When specified (see 6.2), a kit shall be provided to allow the side loading and unloading capability of specified containers and specified payloads from and onto trucks or trains, on level grade. The side loading kit shall also permit cross loading between modes of transport and positioning of containers over short distances (100 ft) when lifted from the sides.

The kit shall provide the capability of side lifting the container up to 60 inches above ground level.

Use of the side lift capability shall not require any special tools or equipment. The kit shall consist of all necessary hardware, equipment, and instructions necessary to safely attach the mobilizer to the container sides, raise it to the maximum height, lower it to grade, and detach from the container.

When the kit is installed on the mobilizer, all kit hardware and equipment is to be stowable on the mobilizer when not in use.

2.9.4.1 Side loading configuration. The operational cycle for side loading consists of uncoupling an empty mobilizer, attaching to the side of the shelter, and raising the shelter to the maximum height (on smooth, level grade). The cycle shall be completed in 30 minutes by four personnel under normal conditions. The reverse procedure, including stowage of the side lift components, shall not exceed 30 minutes.

2.9.5 Coupling and uncoupling performance. A single mobilizer half shall be designed to be easily maneuverable by the crew over all types of terrain likely to be encountered in deployment in preparation for coupling to a shelter. The manual effort in aligning the mobilizer unit with the shelter prior to coupling shall be minimized. A flexible element is required to achieve, by mechanical assist, the final coupling alignment after the mobilizer unit couplers are within a few inches of the ISO container fittings. Alternately, the mobilizer’s diesel engine can be used to power the unit into alignment with the shelter. If a hydraulic system is used on the mobilizer, the reservoir shall include a dipstick or sight glass for fluid measurement. The system shall function effectively with the container on the ground or raised up to a height of 1 ft on uneven terrain.

2.9.6 Lifting system. A lifting system, hydraulically driven by a diesel engine (see 2.10), shall be required to lift the shelter into travel mode, i.e. up to required ground clearance with the suspension active. The capacity of the system shall be sufficient to lift shelter weights of up to 20,000 lbs with maximum CG shifts as prescribed in 2.7. The lifting system shall also allow sufficient adjustment for aircraft boarding. The system shall also be able to relieve the payload from the wheels while the dolly set is attached to the deployed shelter. The lifting system shall have a positive mechanical lock to secure to a shelter in the travel mode. The dolly set shall be able to position the shelter to a level position when one wheel is 12 inches lower than the opposite wheel on the same axle relative to the floor of the shelter, or an 18-inch variation from one end of the shelter to the other.

This could result when one corner of the shelter is on the ground and the diagonal corner would be 30 inches above the ground. It is desirable that the shelter access door be accessible in either position, but not unreasonable to require the door face downhill in these extreme conditions.

2.10 Engine.
