Gantry Cranes are generally used for moving heavy loads, often outdoors. EMH has designed and built many large gantries with features such as rotating hoists, multiple hoists and enclosed cabs.
Can be used where overhead runways are not practical
A much greater bridge weight than an equivalent overhead crane
Capacities, spans and heights are virtually unlimited
EMH builds a complete range of gantry cranes for indoor and outdoor use including:
Single Girder
Double Girder
Single Leg
Cantilever Style
Indoor and Outdoor
A 90 ton gantry crane with a 14 ton auxiliary hoist at a New England power plant.
A 25 ton, 120 foot span outdoor gantry crane loads wall panels onto flatbed trucks. A single rotating “hammerhead” hoist, designed and built by EMH, provides precise positioning of the load.
This single leg, double girder gantry crane has a pass-through cantilever that allows hoist movement beyond the wall on the left. A fully enclosed cab controls all crane functions.
Several EMH gantry cranes are used at a major West Coast shipbuilding facility.
A double leg gantry crane with torsion box girder construction in a steel facility is shown above.
A 130/25/15 ton, 105 foot span, double girder gantry crane installs and services turbines at an overseas power plant. The crane uses three EMH engineered hoists. Two are mounted on a double girder trolley with service walkways and a torsion mounted hoist runs along the side of one girder. The crane uses eight bridge drives. The all-inverter controls are mounted in a stainless steel enclosure, covered by a sun shade, and air conditioned.
10 ton single leg gantry allows loads to be transferred across 3 bays. Note the drives are both mounted on the top rail and include guide rollers for guidance. As a result, polyamide wheels at floor level eliminate the need for crane rail.
