Tal manual gear: characteristics, purpose. Hoist chain

Organization of logistics processes is focused on the maximum optimization of the resources during the implementation of each phase. To support high speed operations often use special equipment. A special category of present devices and assemblies, providing cargo service. Such is the tal manual gearwheel, characterized by simple construction and high reliability.

Purpose

Most Often hand hoist, also referred to as hoists, used at storage sites. The fact that, in General, the segment of lifting equipment this device can be considered as the initial level, and therefore the scope of application is considerably limited. Manually using this mechanism, you can lift small loads that might be found in shops, workshops, restaurants, etc. of Course, tal manual gear itself focused on facilitating recovery, but still her life has limitations. On the other hand, at sites where such equipment is used, often simply do not exist conditions for the use of alternative lifts.

Construction and principle of operation

As part of the basic design is a drum, drive mechanism and transfer system. In this case, the device chain hoist, which involves manual control. As optional equipment hoist chain may provide special beams or rails for movement. The need for such infrastructure provision depends on the needs of a particular object. When it comes to maintenance the production line, it is possible that such an option is justified, but for a point permutation of the quantities of goods in movement is unlikely to be a particular need.

With regard to bringing Tali into effect, there are two approaches to the realization of Executive part. This worm and gear system, which have fundamental differences, although both are manual. Worm models are flexible in use, require less effort from the user, but tal manual gear wins due to reliability. And this operational indicator directly goes to security, which is very important in the work with the goods.

Key features

Of Course, the main indicator is the carrying capacity. It determines what goods will work on this unit. Range of admissible loads range from 250 kg to 10 t. With small carrying capacity of the chain hoist can be used in the private sector – for example, in vehicle maintenance. Models with a 10-ton loads, often used in production. By the way, the potential carrying capacity directly determines the weight of the hoist, which can range from 20 to 150 kg. Therefore, it makes sense to initially evaluate the ability of the ceiling to carry such loads.

The Following important characteristics-height, which may be the mechanism. It varies from 1.5 to 12 m. In this setting, it is important to pay attention if there are serious limitations in the parameters of the room. For example, if we are talking about the garage with a low roof, or, on the contrary, the workshop room with high ceilings. What else touches the ceiling, it is important to note that the tal manual gear mobile will require the relevant infrastructure. It is important to consider and of the possibility of such solutions in terms of a square moving, in relation to the technical possibility of installation of the respective rails. It is necessary to assess the load carrying structure of the ceiling finish material and to correlate these data with the requirements of the specific installation kit.

Varieties

Consider a tal can be classified as manual, gear-snap-in to perform the lift. But, as already noted, there are mobile models, which means – and units fixed. The first option is preferable, if we are talking about large spaces where required and the horizontal movement of the material. In turn, tal manual gear stationary most suitable for small warehouses, shops or garages. This is the best option if you intend to use the mechanism in close conditions. Additionally, stationary devices do not require additional work for installation of suspension ceilings.

Manufacturers

Manufacturer of manual hoists are engaged in both foreign and domestic companies. Among foreign brands can highlight Grost, JET and Kraftool. These manufacturers have been developing warehouse, construction and automotive tools and equipment of high quality. Russian company «Teuton’, ‘bison” and “Caliber” also not inferior to the competitors and offer decent performance solutions. How much is a manual hoist? Average price varies from 4 to 9 thousand RUB does the cost of different models depending on the payload, the weight of the hoist, the maximum permissible height and other parameters. Also influence the costadditional equipment in the form of hoist winches and beam systems.

Conclusion

Hoist is a combination compact, easy to use and simple mechanism by which to lift cargo. In fact, direct alternative variants of such a system practically does not exist. Unless we can point out other options for structural performance, but hoist manual gear chain in its category is the most reliable solution. Such mechanisms are robust, stable running, high maintainability and affordable cost. It only remains to optimally determine the appropriate characteristics of the helper. As practice shows, the winner is the user who not only relied in choosing to direct the operation of the mechanism, but also took into account the ergonomics of the equipment.
