In the world of heavy lifting equipment, there are many
definitions used to classify the numerous types that exist. These take many
forms, from lifts, escalators and continuous transport, to cranes, lifts,
trucks, telehandlers and other similar devices.
Crane: lifting apparatus with a discontinuous operation,
intended to raise and distribute, in space, suspended loads from a hook or
other attachment.
Jib crane: crane in which the arm is suspended with an accessory
pen or a car traveling along it.
In the first case, the load distribution can be effected by
varying the angle of inclination of the pen; in the second case, the position
of the pen is typically horizontal, but it can be used to form an inclined
angle.
Mobile Crane: lifting apparatus with a discontinuous
operation, intended to raise and distribute, in space, suspended loads from a
hook or other attachment arm.
Self-loading crane: lifting apparatus installed on vehicles
suitable for transporting materials. It is used exclusively for loading and
unloading.
Tower crane: A jib type crane fed by detachable power,
specially designed to work as a tool in construction. They can be classified by
its main features:
Stationary: the cranes do not incorporate a manoeuvre
operation, i.e. the ability to move themselves autonomously via rails or other
means.
Supported: Those that focus their severity through weights
or counterweights located at its base.
Built: Those that focus their gravity on the ground, anchored
to a concrete pad or similar means ground.
Mobile: Those that possess the capacity for autonomous
movement.
Climber: Able to rise by climbing systems (wired or zippers)
firmly until the building is constructed.
Telescopic: Able to elongate and rise above themselves
through wide and narrow sections embedded on each other.
Hoist: A hoist is a machine used to lift or move a load. It
has an advantage over other apparatus because it requires much less force to be
applied to the weight. It takes two or more pulleys built to minimize stress.
Hoists vary in size and power; the small hoists are operated
by hand and larger machines have an electric motor. There are rotating
structures, whose entire upper structure, including pen and control unit,
rotate on its base.
Swivel pen: one whose upper structure, including pen, is without
a control unit and rotates on its base.
And lastly, there are pen sets: The upper structure,
including pen, is fixed relative to the base.
These mechanisms are widely used in many industries that
carry heavy materials and elements to make the process easy, quick and for the
direct placement of parts. This could be on a construction site, in workshops,
warehouses, as well as loading and unloading trucks that carry the weights.
