Underslung Cranes

VITAL MACHINES provide a range of quality manufactured and industry-proven running components for underslung travelling cranes. These components are carefully selected and matched with the 'best-fit' hoisting device - to provide you with long-lasting, trouble-free lifting.

Two types are crane systems are offered. Our range covers all loads to 5 tonnes, with a light-weight 'KB' design, for loads under 1 tonne. With a variety of crane components from quality manufacturers, and access to superior local manufacturers, our crane solutions give you robust solutions that require virtually no maintenance.

Whether you seek individual components for your own concept, or wish to source a turn-key solution, then we are definitely here to assist you!

Applications

Underslung cranes remain a class above standard monorails and jib cranes by their ability to provide geometrical coverage of a given work area. Their cost effectiveness rest on the capacity you demand, and the availability of suitable structural supports.

For workstations, many customers prefer to erect a purpose-built freestanding structure. These structures eliminate the need to rely on the building for support and the structures can be repositioned within a factory given any future need.

Whether freestanding or suspended from the building, underslung cranes are cost-effective given their functionality. Matching a single crane to one or two workers guarantees an excellent return-on-investment for most buyers in the manufacturing sector. In heavy workshops, all the crane motions can be motorised - letting the operator concentrate on safety.

For smaller loads, we recommend the use of light-weight crane systems. These designs provide user-friendly load lifting and shifting - whether it be in a workshop, process area, or laboratory. Light weight designs, like GIS 'KB' track profiles, permit manual load shifting. This is achieved due to the special enclosed design of the track profile and matching running gear. Coupled with a GIS electric chain hoist, operators are able to work independently, swiftly and safely.

Technical

Our light weight cranes systems start at a low 30kg and currently extend to 1 tonne. They utilise the track profiles from GIS and Wampfler, for superior quality and component longevity. These designs permit manual push/pull travel of the bridge and hoist trolley, with minimal operator effort. For areas where the process demands powered travel, we then offer a variable speed 'tug' that readily connects to the bridge or runway trolleys.

A range of hoisting gear is available for suspension from the load trolley on the bridge. This includes any size-matched GIS electric chain hoist, as well as spring balancers, air hoists and manual hoisting gear (recommended for maintenance applications only).

For loads under 250kg we recommend the use of the GIS 'GCHHK' Chain Handy hoist. This unit has its control buttons at the hook handset, giving the operator a free hand for greater control of the task being performed. These light-weight profiles are limited in capacity and where the runway and bridge spans exceed 6 or 8 metres they may require additional support or self-stiffening. In addition, GIS provide us with software that contains selection criteria and pricing information. This service is offered to you free-of-charge.

For crane designs between 1 tonne and 5 tonnes, we normally offer runways and bridge members from commercially available hot-rolled sections. This permits use of standard girder trolleys, normally motorised for ease of use.

Our underslung cranes can be as short as a few metres, up to our recommended maximum span of 18 metres. We recommend the use of dual speed drives in all directions, due to their low-cost and safe approach speeds. Radio controls can be offered on any crane system and supplied with a back-up pendant if warranted.
