Any arm which swings about a vertical axis at one end, used for supporting a suspended weight.
A machine for raising and lowering heavy weights, and, while holding them suspended, transporting them through a limited lateral distance. In one form it consists of a projecting arm or jib of timber or iron, a rotating post or base, and the necessary tackle, windlass, etc.; -- so called from a fancied similarity between its arm and the neck of a crane See Illust. of Derrick.
To cause to rise; to raise or lift, as by a crane; -- with up.
A machine for hoisting and moving heavy objects using cables attached to a movable boom (arm).
A materials handling device that lifts heavy items. There are two types: bridge and stacker.
n: a machine for raising, lowering, and revolving heavy pieces of equipment.
A machine designed to move materials by means of a hoist.
A mobile unit equipped with boom, cable, and draw works, capable of 360-degree rotation around a center pin. Rated in ton capacity.
A machine used to raise, lower or move a load horizontally.
A machine for lifting heavy weights; may be hand or power operated. Type include electric, gantry, jib, monorail, etc.
lifts and moves heavy objects; lifting tackle is suspended from a pivoted boom that rotates around a vertical axis
a machine that can both lift objects and move them horizontally
a machine that is capable of raising and lowering heavy objects and moving them horizontally
a machine with a boom, primarily designed to raise and lower heavy loads
an example of heavy machinery
a piece of industrial machinery used for working on tall buildings or for lifting containers onto and off of ships in port
a tall machine that is used to display heavy objects or materials
a type of tower that is equipped with pulleys and cables and is used to lower and lift materials
a vertical lifting device
A material handling device used for lifting heavy items. There are two types: bridge and stacker.
machine for lifting and moving heavy weights. Cranes may be mobile, floating or fixed to the shore or to the deck of a ship. Operationally, the important features are the maximum allowable lift, referred to as the safe working load (SWL) and the outreach or distance outwards, which the crane can reach for picking up or putting down cargo.
A large machine that straddles the railroad track for the purpose of loading and loading containers and trailers to and from railcars.
An appliance intended for raising and lowering a load and moving it horizontally, but excluding industrial lift trucks, earthmoving machinery, amusement structures, tractors, industrial robots, conveyors, building maintenance equipment, suspended scaffolds and lifts.
A device for lifting and moving heavy weights. There are two types of traveling cranes: one, the over head crane, a bridge like structure which moves on parallel tracks above and operates inside work areas, and; two, the gantry crane, which supports the bridge on its own legs that move on fixed tracks and usually operated outdoors at ground level. The one leg gantry combines features of both. The jib crane has an arm guyed at a fixed angle to the head of a rotating mast. The boom of a derrick is also considered a crane.
A machine consisting of a rotating superstructure for lifting and lowering a load and moving it horizontally on either rubber tires or crawler treads.
A machine for lifting and lowering a load and moving it horizontally, with the hoisting mechanism an integral part of the machine.
A machine for lifting and lowering a load, and moving it horizontally. Cranes, whether fixed or mobile, are driven manually, by power, or by a combination of both.
a machine for lifting and moving heavy weights
Any one of the various motorized, machines for lifting or moving heavy weights by use of a horizontal bean or movable projecting arm traveling on an overhead support. They are used on construction sites for many jobs.
A crane is a mechanical lifting device equipped with hoists, wire ropes and sheaves that can be used both to lift and lower materials and to move them horizontally. Cranes are commonly employed in the construction industry and in manufacturing heavy equipment. Construction cranes have either telescoping, lattice or articulating booms.
A railroad crane or a crane car is a piece of rail transport maintenance of way equipment. It generally resembles a conventional fixed-location crane except that the platform the crane sits on is a heavy-duty reinforced flat car. Directly underneath the center of gravity for the crane is a pivot point that allows the crane to swivel around 360°; in this way the crane can locate its boom over the worksite no matter what its location is along the track.
