The gripping device and the container

In many areas of industry, manufacturing, and also in the process of warehouse maintenance requires auxiliary equipment for manipulation of various goods. In the broadest sense of the gripping device include hooks, slings, lifting devices, traverse and other mechanisms that perform the task of fixation. Some models also carry out the lifting operation, which increases their functionality. Usually the design of the lifters provide for a hoist, crane, winches and hooks, designed to perform manual materials handling activities. In turn, the container acts as an additional or standalone device that allows you to store or transport cargo.

Scope

Lifters, like Tara, are typically used by personnel who work with cranes. Employees of the transport and industrial enterprises, among which the machinists, crane operators, mechanics and operators, also provide and maintain the equipment. But the vast majority of the gripping device and the container used by the slingers, and other professionals who manage crane installations, through radio channels. In addition, they carry out the inspection of the technical condition of the devices before their use.

Device lifters

The design of the lifters, as a rule, consists of two basic elements: the connecting device and the hook. The first component provides indirect or a direct coupling of the crane with gripper. This connection may be made through the same mechanism on the crane or by traverses through its metal structure. The element also bears the name rope or chain mechanism, link, and shackle. Not less important part, which allow the gripping device and the container is a hook that is directly in contact with client load. The device can be used as a standalone device. Due to the possibility of detaching the structure from the hoist and the load it is called removable.

Classification of lifters

Representing a vast group of devices, lifters vary in many characteristics. So, depending on purpose are universal and special models, and by the nature of the operations – handling, balance and restraint. In addition, devices differenziata design, which, in turn, determines the type of retention. For example, the eccentric, lever and V-lifting devices ensure the clamping fixation, the grabs allow you to scoop up loose mass, and standard modifications with the traverses support the load. There are other models, but they are used rarely. In particular, electromagnetic devices operate by gravity, which allows them to apply only in special circumstances.

Tara in the system of lifters

Along with fixing the lifting loads on the enterprises of a full cycle usually provides the conditions for their storage, moving and storage. To perform these operations, and serves as a reusable container – in fact, the capacity of complementing removable hoisting devices by means of special clamps. In its manufacture use different materials – this, for example, can be metal or plastic (in modern versions) fixtures. In some embodiments, applies a combination of metal and wood. From the traditional ways of storing such devices differ in the availability of mechanisms for leads. With them and performed on the payload.

Varieties of containers

Depending on the business or organization, it is assumed cargo service with defined characteristics. In addition, different conditions and the technical feasibility of fixing, lifting and storage. Consequently, there are several models packaging, which can be applied in certain cases, as, indeed, of the gripping device, the structure of which is much wider. It is important to note that the representatives of the same type in the restraint equipment often have the best types of containers – that is, it is necessary to match the characteristics of devices from the two categories.

For services of goods of small weight and dimensions of used soft packaging. It's inexpensive and the easiest option is presented in the form of bales, nets, sacks and bags. In the category of semi-rigid containers include the grille, buckets and baskets, which provide lifting of removable fixtures with a higher strength (metal). Such devices are suitable for transportation of bulk cargoes. A rigid container is used if you want to take the load and external forces. This group includes high strength moulds, containers, barrels, boxes and other types of containers capable of ensuring the safety of the goods against mechanical influences.

Checkthe health of the lifters and containers

Because of the lifting and holding manipulation involves a high responsibility, the equipment used must meet the operational standards. There are two ways of checking devices on the basis of which shall conclusion, their willingness to use. First, it is the inspection of the technical condition, which includes inspection of lifting devices and containers directly by the owner. Second, the survey modalities, which is conducted by the expert Commission. Usually such events take place at industrial facilities, whose activity is associated with hazardous industrial processes. As the duty of prevention is worth to note every shift visual inspection of the equipment performed by the slingers before work.

Examination Procedure

In accordance with the rules, the inspection of removable hoisting devices provides for the creation of optimal conditions for the detection of defects and verification of the technical capabilities of the design. For example, checking the exposed equipment that is in working condition and at the time of the survey is fixed in the corresponding crane. Slings can be inspected in a special place. If provides for the examination of a large number of instances, it is necessary to perform sorting by type, characteristics and capacity. Usually slings are checked near the place of operation with the expectation of continued application.

Capacity as a very important component of the entire system of holding and lifting also requires attention to his condition. Tara, as the main hoisting devices must have the corresponding technical documents. In order to simplify the inspection necessary to provide accessibility to items intended for transportation of containers. It is checked in isolation from the place of operation, it is possible to examination without the use of special crane. However, this does not mean that in every case excluded the test containers on the ability to work with lifting device – for this and provides the tools hanging.

Defects

During the validation process, it is possible to identify many defects and damage in equipment which is not assuming its continued operation. In particular, inspection of lifting devices can detect cracks in metal structures or welding seams, corrosion, delamination, frame, etc grabs often found insufficient elastic seals, and lack of integrity. Regarding the containers the possible failure of the fixing and locking mechanisms with the risk of arbitrary disclosure of the container during lifting or unloading, but more often there are signs of corrosion or abrasion severe deformity.

Repair actions

After fixing abnormalities of the technical condition of lifting devices it is possible to conduct repair. But it is allowed in all cases, so defective load-handling attachments and containers are frequently subjected to disposal. To work, which is typically in the format of recovery, is the welding of important components (grips, levers, hinges, etc.), edit the individual parts, sealing terminations on the cables, replacing, fixing elements and other activities. After this test, and assesses the suitability of the equipment for further work.
