A crane is a mechanical tool for lifting and moving heavy loads, which was used instead of human and animal power after the industrial revolution. Today's cranes use electricity to perform their tasks. Today, a crane is a device that, using electric power, with or without human guidance, can carry out the activity of lifting and moving the load suspended in the air through a hook or other similar equipment. These cranes are divided into two categories: mobile and fixed cranes.
What is a ceiling crane?
A crane is a type of machine that carries heavy objects using chains and pulleys. Overhead cranes are similar to bridges that are installed on two parallel horizontal rails at a suitable height along the length of the walls of the hall or industrial shed or warehouse, so that they can move the load along the longitudinal axis. A movable hydraulic carriage is placed on the upper or lower part of this bridge to move along the bridge in the transverse axis of the hall and provide the possibility of crane access in the transverse axis.
The most important function of a crane is to lift heavy objects from the ground, that's why there is a pulley in the central part of the carriage, which retracts and unfolds a metal cable for suitable heights. This metal cable is connected to the hook set at its end to allow the overhead crane to lift, move, move and implement heavy loads.
Types of overhead cranes
Double-bridge or double-bridge overhead crane
As the name of the double-bridge crane suggests, it is a double-bridge crane that increases its efficiency. The double bridge overhead crane is one of the most suitable options for high roofed places. This crane is also effective for use in spaces that have a wider opening.
The double bridge overhead crane has the ability to carry and move heavier objects compared to the single bridge. Both this crane and the single bridge crane can move transversely and longitudinally in indoor environments. The double bridge overhead crane can support the weight of heavy objects more than fifteen tons.
Single-bridge overhead crane
Single-bridge overhead crane can carry heavy objects weighing up to 15 tons. This crane is usually used in roofed spaces whose shed opening is less than fifteen meters. This type of crane is less expensive than the double bridge overhead crane. The single bridge overhead crane has a light weight and this light weight makes it easy to do the work. Some of the features of the single bridge crane include the following:
Suspended overhead crane
A suspended overhead crane can be installed in places where the distance between the crane rail and the rafter (inclined beam) is small and it is not possible to move the engine on the crane. . Hanging overhead crane can carry and move objects in any place and direction. Hanging overhead crane has two types of curved hanging and straight hanging. With the help of a hanging overhead crane, you can move loads with a high weight capacity of up to ten tons.
overhead crane
overhead crane has two types of single bridge and double bridge. This crane moves transversely to carry the load and its weight is also light. Single bridge overhead crane has very small dimensions. This type of crane can be used in places where the ceiling is higher. It is cost-effective to use a overhead crane to carry a load of less than 15 tons and a width of less than 20 meters.
Gantry crane
The gantry crane is installed in open places. The gantry crane has two types, single bridge and double bridge. A gantry crane has a horizontal pole, which may be used as a grid due to its efficiency. To make a gantry crane with a pair of bridges, these two bridges must have a standard distance from each other so that there is no problem when moving objects. Another thing that is important is the angle value that is specified between the columns.
Semi-gantry crane
The difference between a semi-gantry crane and a gantry crane is in the radius of operation of this device. The semi-gantry overhead crane has less ability to carry heavy objects.
Wall-mounted crane
The wall-mounted crane has the ability to bear the weight of objects up to a capacity of 5 tons and has a 10-meter-long arm. Also, the wall crane can be used at different heights.
