In many areas of industry, production and during storage service required accessories for handling various cargoes.Broadly speaking, handling devices include hooks, slings, lifting devices, traverses and other mechanisms that perform the task of fixing.Some models also performed lifting operations, increasing their functionality.Usually lifters design elements include the presence of hoists, cranes, winches and hooks, designed to perform manual materials handling activities.In turn, the packaging acts as an independent or additional device which allows you to store or transport the goods.
lifters, as well as containers, commonly used by personnel who work with cranes.Employees of transport and industrial enterprises, including machinists, crane operators, mechanics and operators, and also ensure the maintenance of efficiency of the equipment.But the vast majority of handling devices and containers used slingers and other professionals who manage crane systems via radio.In addition, they carry out inspection of the technical state of devices before they use.
design lifters usually consists of two basic elements: a connecting device and directly hook.The first component provides a direct or indirect coupling with the capture of the crane.This compound can be produced by a similar mechanism on tap or by the traverse through its metalwork.Element is also known as rope or chain mechanism, managers and staples.No less critical part, which is based on the handling devices and containers, is a hook, which is directly in contact with the load being served.The apparatus can also be used as an independent device.With the ability to detach from the design of the hoist and the load it is called removable.
an extensive group of devices, lifters differ for a variety of characteristics.So, depending on the destination are universal and special models, and by the nature of the operations - manipulation, rocker and hold.In addition, the devices are differentiated by the structure, which in turn determines the type of containment.For example, eccentric, lever and wedge handling devices provide a clamping fixation grapples allow scoop loose weight, but the classic version with cross-members to support Georgia.There are other models, but they are used rarely.In particular, the electromagnetic device operate by gravity, which allows them to be used only in special circumstances.
packaging system lifters
Along with fixing and lifting of goods, factories full cycle usually provided conditions for their storage, handling and storage.To perform these operations, and serves as a reusable container - in fact, the capacity of supplementing removable hoisting devices by means of special clamps.It is manufactured using different materials - is, for example, may be metal or polymer (in current designs) devices.In some embodiments, the combined use of the base metal and wood.From traditional methods of storage devices such mechanisms are distinguished by clues.By using them and operations are performed to capture the cargo.
Depending on the business or organization is expected cargo service with certain characteristics.In addition, different conditions and technical feasibility of fixing, lifting and storage.Consequently, there are several models of containers that can be applied in certain cases, as, indeed, and handling devices, this classification is much wider.It is important to note that representatives of the same type in the trapping equipment often are optimally suitable types of vessels - that is, it is necessary to correlate the characteristics fit into two categories.
To serve small cargo weight and dimensions used soft packaging.This is an inexpensive and easiest option presented in the form of bales, nets, bags and Kul'kov.The category of semi-rigid containers include grilles, tubs and baskets, which provide a service load handling removable devices with higher strength (metal).These devices are suitable for the transportation of bulk cargoes.Rigid packaging is used if you want to take the load from external forces.This group includes high-troughs, containers, barrels, boxes and other kinds of containers, capable of ensuring the safety of cargo from mechanical influences.
Verifying lifters and packaging
Since the lifting and holding manipulation involve high responsibility, the equipment used must comply with performance standards.There are two ways to test devices on which to express an opinion about their readiness to use.Firstly, the revision of this technical condition, which provides for inspection of lifting devices and containers directly to the owner.Second, the survey mechanisms, which is conducted by the expert commission.Usually, such events occur at industrial sites whose occupations are associated with hazardous industrial processes.As the duty of prevention is worth noting, and every shift visual inspection of the equipment performed Sling before work.
In accordance with the regulations, inspection handling removable devices provides for the creation of optimal conditions for the detection of defects and test the technical capabilities of the design.For example, checking the exposed equipment that is in working order at the time of the survey attached to the respective crane.Slings can be inspected in a special place.If the survey provides a large number of instances, it is necessary to sort them according to the type, performance and capacity.Typically, the lines are checked near the site of operation with the expectation of continued use.
tanks, as a very crucial component of the entire system of containment and recovery also requires attention to his condition.Tara, as well as basic handling devices, it must have the appropriate technical documentation.In order to facilitate the examination is necessary to provide accessibility to the elements for the transport of containers.It is checked in isolation from the place of operation, that is possible without the use of a special inspection of the crane.However, this does not mean that in every case excluded testing of packaging options for the ability to work with lifting devices - for this and provides tools hanging.
The verification process may identify many flaws and faults in the equipment, the presence of which does not require its continued operation.In particular, the inspection of lifting devices can detect cracks in metal structure or welds, corrosion, separation frame and so on. D. Grapples often found insufficient elastic seals and tightness.Regarding packaging possible inoperability latching and locking mechanisms with the risk of an arbitrary opening the container during lifting or unloading, but most common signs of corrosion or abrasion with severe deformation.
After fixation abnormality technical condition of lifting devices may conduct reconditioning.But this is not allowed in all cases, so faulty handling removable devices and containers are often subject to disposal.The works, which are usually produced in a format recovery, is responsible welding components (grips, levers, hinges and so on. D.), Edit individual parts, sealing terminals on the ropes holding the replacement of fixing elements and other activities.After that conducted the tests and assesses the suitability of the equipment for further work.
