Any industrial production in varying degrees associated with the installation dimensional and complex goods. In many cases, the person to independently perform such work cannot. For this purpose, the rigging tools, mechanisms and fixtures. With their help, moving, unloading, loading objects of any shape and weight becomes available.
They represent operations associated with lifting, holding and moving various objects – components, assemblies and equipment. The key difference of these works from the usual loading and unloading is the use of special devices. Often Rigging tools, fixtures have a specific configuration. Their use is due to the impossibility of implementation of moving objects, due to their dimensions, weight other ways. The timing of works and their cost are determined by the complexity of the operations, the feature of the cargo and the presence of specialized organizations in the region.
Lifting mechanisms – fixtures used for the transport of large equipment. The main objective of the work with the use of special equipment is not to exclude human participation in them, and in improving the efficiency of operations. The services of riggers are industrial enterprises. Lifting devices reduce the time to move belt conveyors, machine tools, workbenches and other large equipment. In addition, the equipment allows to increase the safety of operations and to ensure the safety of the cargo. Lifting devices are used not only in industry, where transportation of equipment is one of the most important parts of the workflow. Often special equipment is used in the domestic sphere. For example, the services of specialized organizations have resorted to the need to transport safes, musical instruments, furniture, etc.

The company offers relocation services, heavy goods used in their work by various devices. They are all United by the term "snap". In practice, there are mainly the following Rigging prisposobleniya:
As a rule, used steel, nylon and hemp ropes. The latter can be Smolny or belnye. They differ in production technology. Hemp yarn, impregnated with resin, are considered to be more practical. In addition, they possess high strength. Belnye ropes – more flexible. They have a smaller margin of safety and are not used for machines equipped with machine drive. For installation of such ropes are rarely used. Steel cables differ in sectional shape and are classified according to the design feature. Usually used round and flat ropes with single, double, triple stranding.
These Lifting devices represented by pieces of ropes of different configurations. Slings are used for reliable and quick fastening of transported cargo. They can be electronic and manual. Slings are used in direct loading/unloading. The maximum height, which can lift a load, - 3 m. the maximum weight of objects to move which use slings, – up to 10 tons. For lifting a small height are used jacks. They can be screw, gear, wedge, hydraulic.
These mechanisms are usually part of different lifting equipment. The VG represents the most simple lifting device consisting of blocks. The latter are connected by a cable. The blocks differ in number of rollers (single and mnogovolnovye).
Its design is composed of blocks or tackles. Using these elements, the immediate lifting of the cargo. Winches are distinguished by type of drive. It can be electric or manual.
It Often happens that the rigging work involves the suspension and load retention on the structure that can bear its weight. In this case, using hoist. If you are in a room, they are secured on floors and other construction elements. If they are absent, are equipped with special equipment – the substructure. As a rule, it is a metal upright support held special braces. As a support in construction provides heavy plate.
In the production of rigging up and moving quite heavy objects. Their weight can be up to several tons. Experts have developed safety rules when using lifting devices. The requirements take into account all the hazards when carrying out transactions. Employees of organisations that provide handling services, aremandatory training and courses for professional development. To perform the work necessary to obtain a special permit, undergo a medical examination.
Maintenance is carried out regularly Inspection rigging tools, mechanisms and adaptations. The test is performed within the established deadlines. Traverse inspected at least once every six months, Tara, mites and other seizures – 1 p/month, slings – 1P/10 days (also rarely used).
Extraordinary full tehosvidetelstvovanii equipment should be mandatory after repair of metallic elements with the replacement design of parts and assemblies, reconstruction, repair, replacing of hook and other similar operations. The results of the procedure are logged rigging techniques mechanisms and adaptations.
After replacing worn out ropes, when passes checks secure mounting and correct zapakovki is tight cables work load.
Tehosvidetelstvovanii and accounting rigging techniques, mechanisms and adaptations provides engineering-technical workers, at the company performing Supervisory functions, with the participation of the employee responsible for the serviceable condition of the equipment. The latter can independently verify the reliability of the ropes and the correct zapakovki, stitched after the cargo passes, or replacement of cables. The form of a log-lifting means and devices in compliance with Appendix 9 to the Rules FROM when working at height (approved. By order of the Ministry of labor No. 155n 28/03/2014-th,).
Production of rigging involves the use of slings, which are the load lifting mechanism. Before slinging specialist needs to know the entire object. Typically, the weight indicated on the nameplate attached to the frame. If the object is Packed, the weight is marked on the box or the casing. Lifting and moving of items are performed in strict compliance with the following rules:
All goods that are transported, are divided into certain groups depending on the mass:
There is another category of – dead loads. They call the objects frozen to the ground, dug into it, mounted on the base, pinned to other objects. The mass of such goods, as a rule, unknown. To use for lifting the valves is strictly prohibited. Objects are also categorized according to their size and are oversized and overweight. The first parameters do not exceed the standards outlined in the traffic regulations (road transport), or match the dimensions of the rolling stock (for rail transport). In oversized cargo, these figures exceed the established standards.
One of the key factors of security is the high professionalism of the personnel responsible for rigging operations. Employee must be familiar with the equipment he uses, features of its operation. Production is controlled by a foreman. He is responsible for the implementation of the rules and regulations. Staff developed special instructions, derogation from which is fraught with serious consequences.
