Abstract
A mobile service trailer having structural support columns extending vertically from a trailer platform and roof support members which are supported by the support columns and span the width of the trailer platform. A first guide track is suspended underneath and extends between the roof support members. A first crane is positioned on an elongated trolley which travels along the first guide track between an extended position and a retracted position. In the extended position, the trolley extends past the rear end of the trailer platform in a cantilever fashion to enable the first crane to reach and lift an object positioned behind the trailer platform. In the retracted positioned, the trolley is retracted to enable the first crane to deposit the object onto the trailer platform.

TITLE
[0001] Mobile Service Trailer With Crane v FIELD
[0001] Mobile Service Trailer With Crane v FIELD
[0002] There is described a mobile service trailer, which has a built in crane.
BACKGROUND
BACKGROUND
[0003] Mobile service trailers are frequently used to transport equipment to job sites.
However, without lifting capacity the mobile service trailer can only be used to service objects that can be manually lifted into the trailer. What is required is a mobile service trailer with lifting capacity.
SUMMARY
However, without lifting capacity the mobile service trailer can only be used to service objects that can be manually lifted into the trailer. What is required is a mobile service trailer with lifting capacity.
SUMMARY
[0004] There is provided a mobile service trailer with crane which has a trailer platform resting upon ground engaging wheels. The trailer platform has a front end, a rear end, a first side, a second side, and a trailer hitch support extending forward of the front end. A plurality of structural support columns extend vertically from the trailer platform at spaced intervals along both of the first side and the second side. A plurality of roof support members are supported by the support columns and span the width of the platform between the first side and the second side. A first guide track is suspended underneath and extends between the roof support members. A first crane is positioned on an elongated trolley which travels along the first guide track between an extended position and a retracted position.
In the extended position, the trolley extends past the rear end of the trailer platform in a cantilever fashion to enable the first crane to reach and lift an object positioned behind the trailer platform. In the retracted positioned, the trolley is retracted to enable the first crane to deposit the object onto the trailer platform.
In the extended position, the trolley extends past the rear end of the trailer platform in a cantilever fashion to enable the first crane to reach and lift an object positioned behind the trailer platform. In the retracted positioned, the trolley is retracted to enable the first crane to deposit the object onto the trailer platform.
[0005] The mobile service trailer, described above, can be backed up to a piece of equipment needed servicing. The trolley can then be extended in cantilever fashion over the piece of equipment and the first crane can be used to lift it. The trolley can then be retracted, so that the piece of equipment can be lowered onto the trailer platform adjacent to the work station where the piece of equipment is to be serviced. There are various ways of configuring the first guide track. Beneficial results have been obtained when the roof support members have a depending framework and the first guide track is defined by a channel defined by the framework which accommodates the trolley.
[0006] For some pieces of equipment, servicing requires multiple work stations. In such a situation, it may be necessary to repeatedly reposition the piece of equipment on the trailer platform to access different work stations. In such cases, a second guide track may be provided extending between the front end and the rear end, with the second guide track being supported by the support columns. A second crane can then be positioned on a beam that extends across the trailer platform between the first side and the second side. The second crane is capable of travelling along the beam between the first side and the second side. The beam is capable of travelling along the second guide track between the front end and the rear end. This enables the second crane is able to lift the object deposited by the first crane and reposition the object axially and laterally to any desired location on the trailer platform.
There are various ways in which the second guide track can be configured.
Beneficial results have been obtained when the support columns have an upper ledge and the second guide track is comprised of parallel crane rails. One of the crane rails is positioned on the upper ledge of the support columns the first side of the trailer platform and another of the crane rails positioned on the upper ledge of the support columns on the second side of the trailer platform.

One of the crane rails is positioned on the upper ledge of the support columns the first side of the trailer platform and another of the crane rails positioned on the upper ledge of the support columns on the second side of the trailer platform.
[0007] It is preferred that the trailer platform be is enclosed by sheeting secured to an outside of the support columns and roof support members. The reason this is preferred is that it provides a working environment that is sheltered from the elements and it provides better security against trespass and theft of tools. It will be appreciated, however, that the trailer platform need not be enclosed.
