A device with a moving section of monorail or patented track that can be moved to permit the passage of a carrier or trolley from one fixed track to another.
A piece or section of a monorail or patented track system.
An electrically or pneumatically powered drive mechanism that attaches to a trolley or carrier, via a tow bar, and allows the trolley/carrier to move on a monorail or negotiate switches, curves and drop sections. Manually powered trolleys or carriers can be retrofitted with tractor drives, in some cases.
A conveying system which consists of monorail track, track mounted electrification, individually powered vehicles, a supporting structure, a control system, lifts, switches and turntables.
Also known as a trolley. A unit that travels on the bottom flange of a monorail or patented track beam, jib crane or bridge girder to transport a load. Also refers to a trucking line used to transport materials to and from a distribution center.
A hoist that utilizes wire rope as the lifting medium. Often powered electrically or pneumatically. This lifting device is made up of a rope storage drum, motor(s), gear box and braking system and is suspended from a monorail or bridge beam(s) by means of a trolley. May also be mounted in a staionary manner. Manual wire rope hoist are generally referred to as "pullers" and operate utilizing a ratchet and pawl tensioning technology.
A trolley or carrier, generally suspended from a monorail or crane bridge, that is capable or designed to be propelled manually. A push-pull trolley.
A generic term referring to crane and monorail equipment built in accordance with the MMA specification utilizing a composite track section incorporating a proprietary bottom flange shape. A monorail track beam fabricated from a "T" section and a running flange. Patented track is characterized by the "hardness" of its load bearing surface and the ability to be bent into curves without deformation of the beam's load bearing surface. The name "patented track" derived from the original patent received by the inventor for the fabrication and production process of the beam(s).
Automated Electrified Monorail describes a conveying system which consists of monorail track, track mounted electrification, individually powered vehicles, a supporting structure, a control system, lifts, switches and turntables as are necessary.
A track section, usually in a rectangular tube shape, that possesses a continuous slot running lengthwise along the underside of the section. This slot permits carriers and end trucks to travel on the interior bottom flange of the track section.
A single run of overhead track on which carriers (trolleys) travel.
