Safety requirements for mine car transportation
(1) The corners of the slope fill, the fill sections with large slopes, and the outside of the high-bank roadbed should be provided with guardrails and retaining walls. The night loading and unloading site should have good lighting.
(2) When the dump truck enters the working surface and is loaded, it should stop at 0.5m outside the excavator's tail rotation range to prevent the excavator from slamming and damaging the vehicle.
(3) When loading the vehicle, the engine is not allowed to turn off the fire, the cab door is closed, and the head and arms are not allowed to extend outside the driving room. It is forbidden to inspect and maintain the vehicle.
(4) After loading the vehicle, the driver or commander of the excavator sends a signal to allow the car to exit the loading location.
(5) It is forbidden to use the rolling method to start the vehicle, and it is strictly forbidden to slide in the neutral downhill. When parking on a ramp, the driver cannot leave, he must use the parking brake and take safety measures.
(6) Motor vehicles should drive at medium speed on the roads in the mining area, and speed bends, steep slopes and dangerous sections should be speed-limited.
(7) Under normal operating conditions, vehicles of the same type are strictly prohibited from overtaking, and the vehicles before and after are kept at an appropriate distance.
(8) When foggy weather and smoke are diffuse to affect visibility, the yellow light and the marker light shall be turned on and the vehicle shall be decelerated on the right side. The distance between the front and rear vehicles shall not be less than 30m according to relevant regulations.
(9) When the line of sight is less than 20m, the vehicle should be suspended on the right and the warning light behind the vehicle must not be extinguished.
(10) When the snow and rainy roads are slippery, there should be anti-skid measures and slow down; the front and rear distance should not be less than 40m; it is forbidden to turn sharply, brake, overtake or tow other vehicles.
(11) When driving near a slope or a dangerous road, the car should be carefully passed to prevent the frame from collapsing and falling. It is forbidden to stop for no reason on production trunks and ramps.
(12) of the motor vehicle by the front railway crossing, the driver should slow Liao Wang, confirmed by security before.
(13) The unloading location must be provided with a firm and reliable parking facility, and a special person command. The height of the parking facility shall not be less than 2/5 of the maximum tire diameter of the various transport vehicles at the unloading point.
(14) The car should enter the discharge site to obey the command. After the unloading, the bucket should be lowered in time. It is necessary to confirm that the dumper is behind and can move the car to prevent the dumping from erecting the high-altitude lines and pipelines.
(15) The dump truck should not be allowed to approach when the bucket is raised and lowered. After the unloading work is completed, the manipulator should be placed in the neutral position to prevent the bucket from automatically rising when the vehicle is driving.
(16) Dump trucks are strictly prohibited from carrying flammable or explosive materials; outdoor platforms, pedals and bodies are not allowed to carry people. It is forbidden to lift the bucket during operation.
(17) It is necessary to strengthen the inspection, maintenance and maintenance of motor vehicles to ensure the operation of the motor vehicle and the front and rear lights are normal, and the brakes are sensitive and reliable.
Flat disk Rotary Damper mainly used for large diameter, small height space. Disk dampers provide energy absorption and rotational deceleration. We offer many different models from mild to extreme. Our disk dampers are the perfect solution for a wide range of applications, from scanner, and glove boxes to auditorium seating to. Disk dampers are designed to control and smooth out the opening and closing of lids, and doors.
Our damper is conducive to performing structural movement in soft, silent and safe environment, mitigating impact load, avoiding strike damage, prolonging mechanical life, reducing noise disturbance, improving product quality and improve customer satisfaction.
