At the construction site, high-rise construction requires the installation of construction hoists as a passage for raw material transportation and personnel entry and exit. What is a construction hoist? Construction hoists are also called construction elevators, outdoor elevators, and cargo elevators. They are manned and cargo construction machinery frequently used in construction. They are mainly used for the interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings.
High-rise construction is dangerous. There are high safety risks in the use of construction elevators, which is a safety issue faced by construction companies. Before the hoist is put into use, safety protection must be done well. The construction hoist must be installed and used in accordance with regulations to avoid unnecessary accidents. So how do we usually check the construction hoist?
1. Before it is put into use, it must undergo a fall test. During use, a fall test is performed every 3 months. It should be carried out according to the instructions. When the cage falls more than 1.2m braking distance during the test, the cause should be found out, and the anti-fall device should be adjusted to ensure that the braking distance does not exceed 1.2m.
2. Inspection of the transmission mechanism: When the cage is fully loaded and descending, the braking distance shall not exceed 0.3m, and the thinnest part of the brake disc or brake block shall not be less than 5mm, otherwise it must be replaced.
3. Inspection of upper and lower limits: The upper limit should ensure that the upper safety distance left after the cage triggers the limit should not be less than 1.8m, and the lower limit ensures that the cage does not touch the bottom.
4. Limit switch: The overtravel distance between the upper limit switch and the upper limit switch is greater than or equal to 0.15m.
5. The feed and discharge door limit, skylight door limit, wire rope break insurance, door wrench lifting weight limiter must all be guaranteed to work properly.
6. The motor, display, video monitor, sensor, call machine, etc. in the operating room can be used normally.
