Organization of logistics processes focuses on the maximum optimization of resources during each stage. Special equipment is often used to support high speed operations. A special category is represented by devices and assemblies providing cargo service. This includes manual gear hoists, characterized by a simple design and a high degree of reliability.
Appointment
Most often, manual hoists, which are also called hoists, are used at warehouse facilities. The fact is that in the general segment of lifting equipment this device can be considered as an initial level, therefore, the scope of application is significantly limited. Manually using such a mechanism, it is possible to lift small loads, which can be kept in shops, workshops, catering establishments, etc. Of course, the manual gear hoist itself is oriented towards facilitating the lifting processes, but its resource also has limitations. On the other hand, in facilities where such equipment is used, there are often simply no conditions for the use of alternative lifts.
Device and principle of operation
The basic structure includes a drum, a drive mechanism, as well as a transmission system. In this case, we consider the device of a chain hoist, which involves manual control. As an additional equipment, the chain hoist may include beams or special rails for movement. The need for such infrastructural support depends on the needs of a particular facility. If it comes to servicing the production line, then perhaps this option will pay off, but there will hardly be a special need for the movement of goods in a point-wise manner.
With regard to the activation of the hoist, there are two approaches to the implementation of the executive part. These are worm and gear systems, which have fundamental differences, although both are manual. Worm models are flexible in use, require less effort on the part of the user, but the manual gear hoist wins due to reliability. And this performance indicator directly translates into safety, which is very important in working with goods.
Main characteristics
Of course, the main working indicator is the carrying capacity. It determines what cargoes can be operated on this unit. The range of permissible loads varies from 250 kg to 10 tons. With a small load capacity, the chain hoist can be used in private households - for example, in car maintenance. Models working with 10-ton loads are more often used in production. By the way, the carrying capacity directly determines the mass of the hoist itself, which can range from 20 to 150 kg. Therefore, it makes sense to initially evaluate the ability of the ceiling to withstand such loads.
The next important indicator is the height at which the mechanism can be located. It varies from 1.5 to 12 m. It is important to pay attention to this parameter if there are serious limitations in the parameters of the room. For example, if we are talking about a garage with a low roof, or, conversely, about a workshop room with high ceilings. As for the ceiling, it is important to consider that a manual gear mobile hoist will require the organization of appropriate infrastructure. Therefore, it is important to provide for the possibility of such a solution in terms of the area of movement, and with regard to the technical feasibility of installing the corresponding rails. It is necessary to evaluate in advance the power structure of the ceiling, the finishing material and correlate these data with the requirements for the installation of a particular kit.
Varieties
The hoist in question can be classified as manual gear for lifting. But, as already noted, there are mobile models, and therefore - units of a stationary type. The first option is preferable when it comes to large rooms, which require horizontal movement of the material. In turn, the stationary manual gear hoist is more suitable for small warehouses, shops or garages. This is the best option if you plan to use the mechanism in tight conditions. In addition, stationary devices do not require additional work on mounting the chassis on the ceiling.
Manufacturers
The manufacture of manual hoists is engaged in both foreign and domestic companies. Foreign brands include Grost, JET and Kraftool. These manufacturers are successfully engaged in the development of warehouse, construction and automotive tools and high-quality equipment. Russian companies Teuton, Zubr and Caliber are also not inferior to competitors and offer solutions worthy of performance. How much does manual hoist cost? The price on average varies from 4 to 9 thousand rubles. The cost of different models differs depending on the carrying capacity, the mass of the hoist itself, the maximum permissible installation height and other parameters. Also, the cost is affected by the additional equipment in the form of a lifting mechanism for winches and beam systems.
Conclusion
The hoist is an example of a compact, easy to use and simple mechanism with which you can lift the load. Actually, direct alternative options for such a system practically do not exist. Unless you can note other options for structural performance, but the manual gear hoist with a chain in its category is the most reliable solution. Such mechanisms are distinguished by strength, stability, high maintainability and affordable cost. It remains only to determine the optimal characteristics of this assistant. As practice shows, the user wins, who not only relied on the direct working qualities of the mechanism, but also took into account the ergonomics of the equipment.
