Sum Home Freight Elevator is a motor-powered vertical lift with box-like pods for multi-storey construction or cargo. There are steps, stepping board mounted on the track for continuous operation, commonly known as escalators or automatic sidewalks, is to serve the provisions of the floor of the fixed lift equipment.
I believe we are no strangers to the elevator, life is often used equipment. So what do you know about the safety of the elevator? The elevator itself is a perfect transport equipment, it uses a variety of security measures to eliminate the fall http://www.jordan11smidnightnavy.com/ , crowded and other security risks. As long as the elevator is properly used and regular maintenance, inspection, there will be no security incidents. The main safety devices are speed limiters, safety gears, and buffers.
Speed limiter is a speed detection device, generally installed in the elevator room or elevator shaft at the top air jordan 11 midnight navy unc , but also installed in the bottom of the situation. When the elevator speed to reach the set of electrical action speed is that it will cut off the elevator through the electrical switch safety circuit, and then cut off the system power supply. If the elevator due to gravity or inertia also continue to speed, will trigger the speed limiter of the mechanical action device, so that limit the rope to stop moving, so pull the safety gear.
The safety gear is a brake device mounted on the bottom of the elevator car or elevator counterweight. It includes the pulling mechanism and the brake mechanism in two parts. The action of the pulling mechanism is to transfer the mechanical action of the speed governor to the brake mechanism and to operate the brake mechanism. After the brake mechanism is acted, the wedge of the inside will lock the elevator on the guide rail and prevent the elevator from falling further.
