The goods placed on them are limited in terms of their trajectory, as well as their lowering and lifting height and the width of the device's bridge. Among the construction elements, a distinction is made between those that are mechanical and those that are electrical. If you choose an overhead crane course, then all the precise information about the construction of the device is given during the class. Below is a schematic overview of the construction of cranes.  Mechanical components: on the travel path - cams and buffers the steel structure of the unit, i.e. the headframes - the travel mechanism, the driving and travel wheel, the buffers, the stop paws, the limit switches, the wind protection and the copper brushes the bridge - usually an I-beam, which is responsible for the travel path of the trolley and contains the buffers travel trolley - constructed from a motor and a geared transmission hoisting mechanism - body, wire rope tendon, drive motor, geared transmission, chain or grooved rope drum, rope guide ring, rods with buffers and limit switch, hook block and hook Electrical components: crane switch - responsible for switching off and on the power supply with the power circuit power switch - responsible for switching off and on the power supply of the crane, it is usually installed on the platform trolleys - current collectors control and distribution cabinets control cabinets for the installation on the bridge control box limit switches All the components are responsible for three basic movements: these are the movements of the platform, the movements of the hoist and the lifting movements of the sling on which the load is placed.
