A gantry crane carries its bridge on freestanding legs that run on floor tracks or castors, so it lifts without the building steel an overhead crane needs. A portable gantry crane suits outdoor yards, workshops, rail sidings and any bay where a runway cannot be mounted overhead. Kranes supplies adjustable-height, portable and full-span gantry cranes for purchase or rental, sized to your load, span and duty cycle. Tell us the weight, the lift height and the working width and we return a quote with the right configuration, hoist and controls — installed, serviced and stocked for parts across Canada.
Gantry cranes come in several configurations, and the right one depends on how you work. A full gantry runs on rails at ground level so trucks and trailers can pass straight through the legs, while a semi-gantry keeps one leg on the floor and the other on an elevated runway to free up floor space along a wall. Single-girder designs are lighter and economical for everyday lifts; double-girder designs carry heavier loads, longer spans and higher hook positions for demanding duty cycles. Portable A-frame gantries roll on castors for occasional lifts in a workshop, and adjustable-height models telescope to clear different loads or move between bays. Whichever form fits, the hoist and trolley travel the full length of the bridge so you can place a load anywhere within the span.
Because a gantry needs no overhead building steel, it earns its place wherever a fixed runway is impractical. Steel-fabrication shops use them to feed plasma tables and welding bays; rail yards and transit depots lift bogies, wheelsets and rolling stock; ports and laydown yards move containers, pipe and precast; and machine shops park a portable unit over a single workstation for engine, die or mould changes. Outdoor units are built with weather-rated motors, sealed bearings and corrosion protection for the Canadian climate, while indoor units can run quieter, lower-headroom hoists. Rubber-tyred and rail-mounted travelling gantries handle the largest spans and the heaviest repeatable picks across an open yard.
Sizing a gantry is straightforward once you know three numbers: the heaviest load, the maximum lift height and the clear working width between the legs. From there Kranes matches the capacity, the girder type, the hoist speed and the duty class, then specifies the controls — pendant, radio remote or cab — and the power supply your site can provide. Buying makes sense when the crane runs every shift and becomes part of your process; renting fits a defined project, a seasonal peak or a one-time installation lift. Either way we coordinate delivery, assembly and commissioning so the crane arrives ready to certify, not as a box of parts.
Every gantry we supply is backed by inspection, certification, repair and parts so it stays safe and compliant for its full service life. Our technicians load-test and document cranes to CSA B167, the Canadian standard for the design, inspection and maintenance of overhead and gantry equipment, and we keep wire rope, hooks, sheaves, wheels, motors, brakes and controls available coast to coast — including for older units other suppliers have walked away from. Send us your load chart, a photo or a part number and we respond with a quote, availability and the service interval that keeps the crane working.
