4.3. Prior to the repair and maintenance of modular machines of manipulator type and with jaw grippers, their working body (boom, manipulator, gripper, etc.) should be set to one of the extreme positions (in transport or lowered to the stop with the ground, floor, stand), relieve pressure in the hydraulic system, unload the hydraulic cylinders by repeatedly turning on and off the hydraulic distributor spools with the pump turned off (engine not running). It is forbidden to carry out work related to the repair and maintenance of the machine with intermediate positions of the working body.

4.4. When repairing, hanging (lifting), moving (towing) the machine, components and assemblies, it is forbidden to use the track pins of tracked vehicles as knockouts and connecting elements in the rope block equipment of the machine and mechanisms.

4.5. The victim or eyewitness must notify the foreman or the appropriate work manager of each accident.

4.6. Each worker must be able to provide first aid. Such assistance is provided immediately, directly at the scene and in the following sequence: first you need to eliminate the energy source of injury (switch off the engine, stop the mechanism, turn off the knife switch, turn off the valve, stop the equipment, etc.). Assistance should begin with the most significant that threatens the health or life of a person (in case of severe bleeding, apply a tourniquet, and then bandage the wound; if a closed fracture is suspected, apply a splint; for open fractures, first bandage the wound and then apply a splint; for burns, apply a dry bandage; in case of frostbite, gently rub the affected area using soft or fluffy tissues).

After providing first aid, the victim should be sent to the nearest medical facility.

If spinal injury is suspected, transport the victim only in the supine position on a rigid base.

5. Safety requirements at the end of work

5.1. Check the availability and tidy up the tool and put it in the cabinet.

5.2. Tidy up the workplace and clean the area where the work was performed. Collect used cleaning material in the designated place.

5.3. Drain spent kerosene and other liquids into a specially designated place (containers). Hand over the workplace (site) to the shift and inform him or the foreman about all the shortcomings that occurred during work and about the measures taken to eliminate them.

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. ... >>

Mean Well LED drivers with Smart Timer Dimming 25.10.2016

Mean Well has introduced a series of programmable LED lighting power supplies with a new Smart Timer Dimming feature. The new range is based on the low cost and reliable ELG family.

The Smart Timer Dimming function provides the ability to program the desired dimming profile with smooth transitions, the ability to program the required constant output current in the range of 10-100%, the ability to compensate for LED aging and obtain a stable light output throughout the life of the lamp, as well as several adaptive dimming options . In this case, you can set or select a self-adjusting dimming profile for changing seasonal daylight hours.

Additionally, it is possible at any time to forcibly turn on the power supply to the maximum output current. The drivers have a control of the total operating time and indication of resource depletion.

Using the programming function, you can set a smooth increase in the output current at the moment the power source starts, which will favorably affect the life of the LEDs and the power supply at the time the line is turned on.

The Smart Timer Dimming function will remove the dependence on LED binning, unaccounted for losses in the secondary optics and ensure an accurate luminous flux of the luminaire.

Power supply models are currently available in series from 75 W to 240 W (ELG-75, ELG-75-C, ELG-100, ELG-100-C, ELG-150, ELG-150-C, ELG-200 , ELG-200-C, ELG-240, ELG-240-C). The presence of the Smart Timer Dimming function is indicated by the ending D2 in the name of the power source.
