Quite often, for some people (such as builders, car repairmen, warehouse employees and others), a need arises for lifting various cargoes. At the same time, this does not always happen within the framework of a workshop or a large construction site, but also in a personal garage, car service or in a personal plot. In order to mechanize the indicated lifting operations, a manual gantry crane has been very actively used recently. We will talk about its device and features in the article.
Appointment
The gantry mobile crane is essentially a versatile portable lifting equipment. This unit is used for loading and unloading in various rooms, and, importantly, it can be used even in very cramped conditions (for example, in the narrow aisles of large storage rooms). Using the named device, you can serve small-tonnage loads.
Design Features
Manual gantry crane can be safely called indispensable equipment for various workshops and service workshops. And all because he has a fairly simple set of his own parts, characterized by a high degree of reliability and strength. In addition, any component of the crane is completely unified and standardized, that is, simply put, in the event of a breakdown of any node, it will not be difficult to buy and replace it. Moreover, many repair work could well be carried out independently without the assistance of third-party specialists.
The main technical characteristics that you should pay attention to before buying a manual gantry crane are:
- carrying capacity;
- lifting speed;
- span value;
- lifting height.
Device description
Manual gantry crane consists of a collapsible metal structure, which, in turn, has a span beam and support legs. The last elements abut the cart equipped with swivel wheels. Moreover, each wheelset is equipped with a special hinge that is installed so that the entire mechanism retains its verticality on uneven sections of the underlying surface. As a safety locking element, brakes are mounted on some models. You can move the crane in space alone.
The paintwork of the mechanism ensures its resistance to the effects of the extremely negative phenomenon of metal corrosion.
The main lifting element of the entire unit is a hand chain hoist, with which the operator has the ability to raise / lower a variety of objects. However, in some cases, at the request of the customer, the hoisting mechanism can be equipped with electric hoist. In this case, by all means complement the system with a soft start.
It is also important that the installation of a gantry crane does not require much time and effort. The device itself, when assembled, moves without any problems within the working area. We point out that the running wheels are often made of polyamide, which does not damage the floor or soil.
Conclusion
The hand-held mobile crane has proven itself in practice. Moreover, its operation can take place in a wide variety of climatic conditions. The service life of the unit is calculated over many years, and therefore the money invested in the purchase of the unit will fully pay off, and the equipment itself will pay off for a fairly short period of time. It’s very convenient that almost anyone can use such a crane, even without special technical skills.
