What a slinger is prohibited from doing. What a slinger is prohibited from doing when performing his professional duties

When servicing the crane, the slinger must follow production instructions, which the enterprise administration is obliged to issue to him before starting work.

When servicing the crane, the slinger must ensure that no people who are not directly related to the operation of the crane are present at the work site for lifting and moving the load. He must also ensure that before lifting the load, the hoisting ropes of the crane are in a vertical position, and not allow the load to be pulled up with a hook when the ropes are tensioned obliquely.

Locating ropes and chains must be applied without knots or loops, and chocks must be placed under sharp corners of the load.

The slinger must ensure that there are no people between the load being lifted and the equipment. This requirement must also be met when lowering the load. Before lifting machines and metal structures installed on the foundation, the slinger must make sure that the load being lifted is not held back by anything; lifting should be done with short movements, avoiding the load touching and horizontal movement until it is completely removed from the foundation.

Every time a load needs to be lifted, lowered or moved, the slinger must personally give the appropriate signal to the crane operator. Before giving a signal, the slinger must make sure that the load is securely captured by the slings, is not being held back by anything and cannot get caught on anything during lifting.

The slinger must ensure that there are no loose parts or tools on the load that could fall when moving the load.

If pipes are being lifted, the slinger should check for soil or ice in the pipes. He must give the command to lift the load. Before moving the load, you must first raise it to a height of 200-300mm and check the uniform tension of the slings, as well as the reliability of the sling.

If the slinger notices that the sling requires correction, he must give a signal to lower the load and begin correcting the sling only after lowering the load and loosening the slings.

Before moving the load horizontally, the slinger must make sure that the load is raised at least 0.5 m above objects encountered along the way, and above the scaffolding - above 1 m.

When moving a load, the slinger must accompany the load and ensure that there are no people under the load. In this case, the slinger should not hold onto the load with his hands, but walk away from it in a safe zone.

The slinger may not accompany the load if the load and the path along which it moves are visible from one place or when escorting the load is impossible. In this case, the load must be monitored by a crane operator or signalman.

The slinger has no right to turn the load, as well as to prevent the spontaneous turn of a long load with his hands. In these cases, it is necessary to use guy ropes or hooks.

The slinger must carry out stacking and dismantling of cargo only in accordance with the norms and rules for storing cargo, observing the dimensions between stacks, buildings and structures and in the places intended for this.

The slinger has the right to remove slings from a load or crane hook only when the load is securely in place.

While the slinger is working prohibited:

· use worn-out, faulty, unstamped or unmarked slings and other equipment and containers;

· carry out work on slinging and hooking loads during rain, thunderstorms, heavy snowfall, as well as during winds over 6 points;

· hook onto the crane hook a load exceeding the crane’s lifting capacity, dead weights in the water, as well as loads in an unstable position;

· hold with your hands or adjust with hammer blows the mooring ropes and chains with which the lifted load is tied;

· be on your own or allow people to be on the railway platform, when working with a grab or an electric magnet;

· load onto a vehicle if the driver is in the cab;

· place cargo in prohibited places.

Each slinger is required to know the safety rules when performing loading and unloading operations and strictly follow them in order to avoid any emergency situations in his activities. They should not forget about what is strictly forbidden to do when moving goods.

When tying and hooking loads, they must avoid:
. Hooking and tying loads in ways that are not indicated on the resulting sling diagrams;
. Using damaged or unmarked removable lifting devices and containers;
. Connecting links of broken chains with wire or bolts, as well as tying ropes;
. Using devices for hooking and tying loads that are not provided for in slinging schemes (this applies to crowbars, pins, wire, etc.);
. Hammering the hooks of the slings into the mounting loops of the loads;
. Using ladders when tying wall blocks large sizes, for this purpose only portable platforms should be used;
. Hanging loads on only one horn of double-horn hooks;
. Using grabs to lift loads that are suspended by the jaws of the grab using slings; They cannot be used to carry out work that is not intended for it.

IN regulatory documents a list of cargoes has been established that cannot be allowed to be slinged, as well as lifted by cranes. These include:
. Loads having a mass that exceeds the lifting capacity of cranes;
. Loads whose mass is unknown;
. Dead weights, that is, those that are secured, littered, or pinched frozen in the ground;
. Cargoes containing people;
. Loads that are in an unstable position;
. Containers that are filled above the sides;
. Products made of concrete or reinforced concrete whose hinges are damaged or are not marked;
. Pallets with bricks that do not have a fence.

To prohibitive points in professional activity slingers include work that is impossible to perform in the absence of direct supervision from the person responsible for the safety of the work. And under their leadership the following work is carried out:
. Loading and unloading of holds and gondola cars;
. Moving cargo using several cranes;
. Loading and unloading operations near power lines;
. Operations with cargo for which there are no sling schemes;
. Working with a load under the roof of a building where there may be people.

When lifting loads, the slinger cannot be: . Under the booms of truck cranes and lifted loads;
. Between walls, stacks, columns, machines and loads;
. In gondola cars, on platforms or in cars;
. In areas of rotation of parts of any cranes.

All of the above allows you to avoid unforeseen situations and injury to people. The guarantee of fulfillment of the listed factors is

A slinger is a specialist whose responsibilities include slinging loads that will be lifted by a truck crane. In this case, it is necessary to perform the following technological operations:

• hook the load;
• tie the lifted object using lifting devices;
• hang it on a hook and give the load the position required for safe lifting;
• unhook the load after moving.

Slinger ranks

The Unified Tariff and Qualification Directory of Works and Professions lists five tariff categories slingers (2-6). Specialists up to the third category can perform work with ordinary cargo, the weight of which does not exceed 25 tons, as well as complex slinging of cargo weighing up to five tons. The appropriate qualifications of the slinger directly affect the safety of lifting operations, and also allow loading onto platforms and heavy equipment with increased level danger.

The dangers of the slinger profession

According to publicly available statistics, almost a hundred slingers and crane operators suffer injuries of varying severity every year during loading and unloading operations. About half a thousand workers become disabled as a result of severe injuries. The cause of almost all such incidents turns out to be negligence or ignorance and gross violation of safety measures by persons who perform lifting work of varying complexity.

The steady increase in cases of injury to slingers and crane operators has led to the need for strict certification of representatives of these professions. Thus, it is possible to determine the specialist’s readiness to perform lifting work of varying complexity and make a decision on admission to perform professional duties. All slingers undergo a special training course and are issued a certificate of the appropriate type.

The slinger must clearly know the following:

• signals given by the operator when the truck crane is operating on the site;
• relevant provisions of the production instructions;
• features of the use of containers and load-handling devices;
• slinging diagrams;
• the procedure for approximate calculation of the weight of any cargo, as well as storage rules;
• container filling standards;
• procedure for inspection and rejection of removable load-handling devices;
• technical characteristics of the slings' lifting capacity;
• maximum length and diameter of slings;
• purpose of all elements of load-handling devices;
• safety measures during lifting operations and production conditions;
• technical characteristics of special equipment;
• rules for handling cargo on sites near power lines;
• content of relevant technological maps.

Before being allowed to work, the slinger must study the operating features of the truck crane. Future specialists receive all of the above knowledge during the training process.

After completing his studies, the slinger should confidently perform the following actions:

• determine the possibility of lifting a load with a set reach and outriggers;
• correctly hook and tie any types of cargo;
• place the cargo in the position required for transportation and unhook the load-handling devices;
• use slings in accordance with the weight and dimensions of the cargo;
• determine the suitability for use of containers and lifting devices;
• understand the signals that should be given to the crane operator during lifting operations;
• use fire extinguishing agents and, if necessary, provide first aid to victims;
• be ready to take action emergency situations and quickly turn off the power to the faucet.
