Mass Crane and Hoist designs, builds, and installs a wide range of overhead crane solutions. These include patented track, enclosed track, single girder, double girder, gantry, and jib cranes. If you're looking for an overhead crane, turn to Mass Crane.

Patented Track Crane

Patented Track is an industry name for an engineered, composite beam specifically designed and fabricated for the overhead lifting industry. The beams are made from a hardened rolled tee section welded to webs and flanges of varying sizes depending on the capacity and span required for the application. These beams (used as both runway beams and bridge beams) have much tighter tolerances than commercially available wide flange beams allowing for smoother splices and less ergonomic effort than a traditional wide flange system. The hardened lower flange is also less resistant to wear or grooving.

Enclosed Track Workstation Crane

Developed in the 1980's, these cranes were introduced as a more economic and ergonomic alternative to manually operated patented track systems. Traditionally limited to capacities of 2 Ton and under and spans of 30 feet or less These systems are typically manually operated (push/pull) for both bridge and trolley motion. Can be freestanding (floor supported with columns and headers) or ceiling-mounted depending on the application and the overhead support structure available. Are a good fit for customers who prefer manual positioning of light capacity lifted loads.

Single Girder Crane

Single girder cranes can be under running (end trucks ride on the lower flange of the runway beam, bridge beam is connected below the end truck) or top running (end trucks typically ride on rail fastened to the top of the runway beam, bridge beam is connected above or to the side of the end truck.) Single girder cranes can be designed and manufactured in a wide variety of capacities, sizes, and spans. The girder on a single girder crane is typically a wide flange beam, although it can be a patented track beam, a truss beam, or a welded box girder for spans over 70 feet. The hoist traditionally rides on the lower flange of a single girder beam.

Double Girder Crane

Similar to a single girder crane, but as the name would indicate, is comprised of two parallel girders connecting the end trucks. Like single girder cranes, these can be top or under-running, though a large majority are of the top running variety. The major difference between single and double girder cranes is that the double girder allows the hoist to ride on top, in between, or below the actual girders. In tight headroom applications, this can create better hook height than the single girder alternative.

Gantry Crane

Gantry cranes are very similar to traditional overhead bridge cranes except that the bridge beams are elevated on legs above the end trucks. In many applications, the end trucks run on rails at ground level, this is a traditional gantry crane. If one rail is on the ground and the other is elevated on runway beams, this is known as a semi-gantry crane.

Jib Crane

Jib cranes typically have smaller capacities, shorter spans, and are often manually operated. The design is based on a fixed rotating mast and boom with a hoist travelling in and out along the length of the boom. As a result the hook coverages are circular in shape. Jib cranes offer a lot of versatility. They can be freestanding, column mounted, ceiling mounted, or any combination of the three.
