The lightest of the goat types is a mechanism with a very simple design. It has four supports and span beams that are connected by special traction, wheels on hinges that create a stable support. All light models are equipped with prefabricated structures that allow you to quickly install the machine. The machine is capable of both immersed and unloading, as well as mount in the shortest time. Helpers have a huge number of advantages. For example, they will not need to make any capital costs that require organizing loading and unloading work. In addition, they are equipped with both electric and any other power supply mechanism. A light unit, like a bridge crane, is even able to change the size, adapt to any requirements of the most fastidious client. The machine will also participate in any regular repair and maintenance of technological equipment. Such mechanisms can be delivered as a basic version, and as a wide selection of modifications — all this depends on the wishes of customers and their solvency.
