Ceiling crane
A roof crane is a structure that is used inside sheds, factories, workshops and other indoor environments to move and carry loads. In almost every industrial environment as well as various industries, when the weight of the equipment reaches more than one ton, the need for a overhead crane is immediately felt. And one of its main advantages is covering 90% of all areas of your area or hall without occupying the smallest useful working space. There are different types of overhead cranes, wall cranes, gantry cranes, semi-gantry cranes, and jib cranes, each of which has its own specific application. These cranes are four-way and six-way in three ways: longitudinal (north and south), transverse (left and right) and vertical (up and down).
Types of Ceiling cranes:
Single -bridge crane
Single bridge overhead cranes are used to move materials in halls with small openings and tonnages of less than 10 tons, which reduces the dead load of the bridge on the columns of the structure and is economically more economical because the total weight It reduces the structure. In single bridge structures, one bridge is placed in line with the opening and two longitudinal guides that move the single bridge structure along the hall on the rails. To move across the width of the opening by means of a trolley located in the lift, which moves it with the motor of the transverse motion of the lift, and the movement along the hall is the responsibility of the longitudinal guides, which are moved by the wheel box and gearbox engine of the lift along the length of the hall. The disadvantages of this structure include lower working class and lower working height compared to double bridge overhead cranes.
Two -bridge crane
Double bridge overhead cranes are the best solution for moving materials in halls that have a span between 10 and 50 meters and a capacity between 1 and 100 tons, and also with this structure you have the best working class and the highest working height. You will receive and also by using engineering calculations and construction of the structure according to the standard and with low dead weight, you can also get the best use from an economic point of view. Also, another advantage of this type of cranes is that despite the selected corridor In the body of the crane, in addition to the ease of access and the possibility of repairing trolley parts, it also provides a suitable opportunity to repair and replace hall lamps, hall heating facilities and power lines.
The crane
This type of crane, in cases where you are not able to install columns and beams, by setting up this system, you have the possibility to easily move objects in the hall area, and this system is also used for moving materials with an opening between 4 and 10 meters and a capacity between 0.5 and 10 tons is widely used, which in this type of structure gives you the possibility of maximum lateral access (more than the opening of the beam) or the maximum working height. It also has the ability to Move the lift in any direction. This type of crane is mostly used in the rail industry, and it is available in two types: straight and overhead cranes.
Ceiling crane properties
A small fee is required to maintain the overhead crane.
The overhead crane can reach all points independently.
The cost to repair the overhead crane is low.
The overhead crane will save energy.
The best option for moving parts that have heavy weight will be the overhead crane.
No special skills are needed to use a ceiling crane and it is very easy to do.
Applications of ceiling crane
A ceiling crane is a device that is installed in the upper part of shed columns in workshops or factories. These types of cranes are made of single-bridge types, such as single-bridge overhead cranes, single-bridge overhead cranes, double-bridge overhead cranes, and double-bridge overhead cranes. Note that the components of single-bridge and double-bridge overhead cranes are not much different from each other except in limited cases. A single-bridge overhead crane uses one bridge to move and carry weight, and a double-bridge overhead crane, such as a two-bridge overhead crane and a double-bridge overhead crane, uses two bridges to move around and bear the weight of the load. Therefore, it is clear that all types of double bridge overhead cranes are able to move very high weights. Therefore, it can be said that these types of cranes are mainly used in large factories. Therefore, based on these two factors, it can be concluded that the price of the overhead crane with two electric bridges can be the most expensive type of overhead crane. Of course, which brand or which country produced it and what after-sales service it provides is also very important in pricing.
Crane crane components
The most important part of overhead crane and any other crane is its winch. A winch is a device that produces the necessary power to move objects. In fact, the fact that you can see that a crane in different models can move objects of several hundred tons, all goes back to the technology of making its winch. The winch is made of three basic components: motor, gearbox and drum. Let us explain a little more. The winch converts the force we give it into mechanical force, and the gearbox adjusts this force according to the user's needs and transfers it to the drum. The drum also causes the load to move by converting the received force into a driving force. Now, the input power can be electric, gasoline, hydraulic, etc. In fact, it mostly depends on the manufacturer and of course your needs. But this is not the whole story. The force applied to the winch must be restrained in some way. In all types of overhead cranes, trolleys or carriages are responsible for receiving and neutralizing this force with the help of bridges. These bridges and the aforementioned trolley must be able to withstand and neutralize the maximum defined force without bending or breaking. Four up and down movements of the crane are done with the help of winch and trolley. However, the north and south movement of the crane is carried out by the guide or clegi, which is a mechanical structure that is made in the form of a box from ST37 sheet or standard sections such as studs or beams and is coupled to the flange of the bridge by a flange on the side. The guide (or head) may be equipped with a driving and moving wheel box at the beginning and end, or the wheels can be placed inside the head box itself. The length of the head box depends on the opening of the crane and its design and construction is done according to the DIN15018 standard.
