To date, the mechanization of lifting work has been given the closest attention. Modern technology in this area allows you to use it even in fairly small rooms to perform a variety of operations (installation, dismantling, loading, unloading, etc.). Therefore, this article will be devoted to a special kind of lifting equipment called a garage crane.
Scope of application
Most often, the mechanism is used in warehouses, service stations. Its basis makes it possible to carry out the movement, lifting of heavy objects with minimal labor. In general, a garage crane combines almost perfect value and technical excellence. It is noteworthy that the price of this lifting mechanism is relatively low, and therefore both large companies and low-budget organizations, including private individuals, can purchase it.
In particular, a garage crane is often used to disassemble and assemble various large engines, motors, transmissions. An impressive indicator of the crane's lifting capacity allows for its reliable and well-coordinated work. The safety of operating personnel will also be fully ensured. A distinctive feature of such a crane is the ease, primitiveness of operation, even an unskilled worker or person can use it without any technical skills.
Advantages
Any hydraulic folding garage crane is endowed with a whole range of positive qualities, among which I would especially like to note:
- Management understandable at the level of intuition.
- The minimum value of inertia and high smoothness of the operations performed.
- Clear fixation of the raised / lowered load at a given point in space for the required period of time.
- Absolute autonomy. For normal operation of the crane does not require any additional energy sources.
- Compactness. The linear dimensions of the mechanism are small, so that it can move without difficulty even in a very narrow space.
Nuances
The garage crane does not require a large number of people for its maintenance. The metal frame of the device is additionally reinforced with special welded elements and high-strength seams. The crane running wheels are securely attached to the base and are usually made from a wear-resistant material called polyurethane. In this regard, the crane, moving along the underlying surface, does not harm it and does not create excess noise.
Device
The hydraulic garage crane in general has the following structural elements:
- Steel frame.
- An arrow with an impressive departure rate.
- Running wheels.
- Hydraulic actuator (hydraulic cylinder, control stick, emergency valve).
- Load chain with load hook.
The well-thought-out structure of the crane provides it with good protection against corner loads. Therefore, the likelihood that this lifting machine will tip over is zero.
The operation of the hydraulic drive allows you to easily move the load in a vertical plane with an accuracy of a millimeter. This is an extremely important feature, especially when it comes to installing high-precision overall parts of various mechanisms and assemblies.
Exploitation
The use of the crane in practice is as follows: manually roll it to the place of work, using the hydraulic pump handle, lower the boom and grab the cargo, and then either transport the crane along with the cargo on the floor, or leave the cargo in suspension. The garage crane has one important feature: the more its arrow is extended forward, the less stability it will have. This should be remembered, since this nuance directly affects the safety of all work performed.
As practice has shown, very often a garage folding crane is used in various car services. Its thoughtful and ergonomic structure allows you to serve cars that are not able to move on their own inside the repair room.
The load capacity of a folding type garage crane can vary from 500 kilograms to two tons. I would especially like to point out that in the process of its storage or transportation, such equipment does not take up much space. When folded, it can be infinitely long.
In conclusion, we say that in hydraulic garage cranes special pressure amplification blocks are very often used, which make it possible to lift objects mounted on a hook suspension much faster. In addition, special safety valves are also available that block the cylinder in cases where the weight of the load lifted exceeds the rated load capacity.
