Safe Operation

Introduction

Employees involved in the operation of cranes of the "DIP" and "Pioneer" types (hereinafter referred to as "employees"), in the performance of work according to their qualifications, must comply with the safety requirements set forth in the "Standard instructions for labor protection for workers in the construction, building materials industry and housing -communal services", of this standard instruction, developed taking into account the building codes and regulations of the Russian Federation, the Rules for the Design and Safe Operation of Load-Lifting Cranes, as well as the requirements of the instructions of manufacturers for the operation of the crane.

e) the supply of cargo into the pit, trench, pit should be carried out if there are at least 1,5 turns of the rope on the drum of the cargo winch (in the lower position of the cargo), not counting those under the clamping device;

f) when lifting the load, do not allow the clip to approach the head of the crane boom at a distance of less than 0,5 m;

g) make sure that there are no people in the danger zone of the transported cargo.

5. When lifting and moving loads, an employee is prohibited from:

a) allow persons who do not have a slinger's certificate to sling cargo;

b) lift and move goods by crane in the absence of slinging schemes and instructions on the mass of goods being moved;

c) lift or turn over a load, the mass of which exceeds the lifting capacity of the crane;

d) pull the load with a crane hook with an oblique tension of the ropes;

e) hook off a load covered with earth or frozen to the base, laid by other loads, reinforced with bolts or poured with concrete, as well as swing the load in order to detach it;

e) to release the removable load-handling devices jammed by the load with a crane;

g) lift reinforced concrete products with damaged hinges;

h) deliver goods to window or door openings if they do not have receiving areas;

i) transfer control of the crane to a person who does not have the appropriate certificate for this, and also leave students or trainees without control for work;

j) lift cylinders with compressed or liquefied gas that are not placed in special containers;

k) adjust the brake of the lifting mechanism with the load lifted;

l) lift bricks, tiles and other small-piece materials stacked on pallets without the use of containers and other lifting devices that prevent the load from falling during movement.

6. During the maintenance of the crane, the employee is obliged to take measures to prevent accidental voltage supply and activation of the electric drive.

7. During the daily maintenance of the crane, the employee must:

a) ensure the cleanliness and serviceability of the crane mechanisms;

b) timely lubricate the rubbing parts of the crane in accordance with the instructions of the manufacturer's instructions;

c) store lubricants and cleaning materials in a closed metal container;

d) make sure that there are no loose objects on the crane structure and its mechanisms.

Safety requirements in emergency situations

8. The employee is obliged to lower the load, stop the operation of the crane and notify the person responsible for the safe performance of work with cranes, as well as the person responsible for maintaining the lifting machines in good condition, in the following cases:

a) in the event of malfunctions of the crane mechanisms, in which, according to the requirements of the manufacturer's instructions, its operation is prohibited;

6) in case of wind, the speed of which exceeds the allowable for this crane;

i) in case of deterioration of visibility, heavy snowfall and fog, when the driver poorly distinguishes the signals of the slinger and the load being moved;

d) at negative air temperature below the permissible value specified in the crane passport;

e) when the rope is twisted or worn, exceeding the values \uXNUMXb\uXNUMXbspecified in the standards for rejecting ropes of hoisting machines;

c) when an electrical, thermal or other protective device is frequently activated.

Safety requirements at the end of work

9. Upon completion of work, the employee must:

a) lower the load to the ground, remove the slings and raise the hook to the top position;

b) set the boom to the position determined by the manufacturer's instructions for the installation and operation of the crane;

c) turn off the switch on the switchboard and lock the switchboard;

d) inform the shift worker, as well as the person responsible for the safe performance of work with cranes, of all problems that have arisen during work.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Portals exist 16.04.2019

Wormholes may exist, but they are useless. This conclusion was made by a group of scientists from Harvard.

Wormholes - "tunnels" in space. Their existence is allowed by the general theory of relativity, but so far scientists have not observed them. The specialists analyzed the hypothesis of colleagues Leonard Susskind and Juan Maldacena that particles in an entangled quantum state can be connected by wormholes.

Scientists believe that the path through a particular wormhole between the two black holes that it connects is longer than the path between them not through the hole.

As stated, in addition to possibly proving the ineffectiveness of wormholes as routes for space travel, the study can help establish a unified view of quantum gravity.
