Rail tower crane
Road tower crane
Along with them, the height of the building increases. This type of tower crane is also used in the industry of tower construction and construction of skyscrapers and bridges.
💢 Important to Choose Types of Crane Tower:
⭕️ Loading power
The loading power in the tower is based on their structure, how much energy it can lift from the ground, which is done by an electric motor. And the electric motor is connected to the gearbox and from the gearbox to the drum or the winch, and by the winch, the required amount of towing wire is connected to the required height of the device and an interface called hook hook to the load. It should be noted that after the driver and the steering wheel, all the above systems are being controlled by a series of micro switches so that the device does not lift more than the permissible load (tonnage) from the ground and the safety of the device is maintained. All these steps are assigned to the load capacity or tonnage of the device. Removing the load from the ground has the maneuver of moving the load forward, i.e. away from the machine (carriage forward) and moving the load backwards, i.e. towards the machine itself (carriage backward). Of course, it should be mentioned that the load that is more than the allowed tonnage of the device is controlled by the microswitches and prevents it from moving forward. Tower cranes, in addition to the ability to lift the load and move it forward and backward, have the power to move the load in a 360-degree radius and move the load to any desired point. Usually, this work is done by 1 or 2 electric motors and 1 or 2 gearboxes, and for its safety, microswitches are installed to prevent unnecessary bypassing when necessary.
⭕️The power of raising or increasing the height
The public is always asked how tower cranes reach high places and how they increase in height.
It is necessary to explain, after the initial installation and assembly which is done by a mobile crane, tower cranes use the self-assembly power of the device to increase the height, which requires a series of very sensitive operations and with the addition The height of the section increases, and by reducing it, the height also decreases, of course, different types of tower cranes have different operations depending on the type or country of manufacture.
Explanation that after The standard height determined by the manufacturer of the device should be restrained by the anchorage frame (belt) to points of the desired building or structure in order to increase the height of the device. Fastening the seat belt etc. should be done by experienced and skilled workers because the smallest mistake can be the last mistake of people.
