What Are The Crane Safety Protection Devices? (2)

What are the crane safety protection devices? According to the Safety Regulations for Crane Machinery, cranes should be equipped with various crane safety protection devices.

(Continued from the previous article)

10. Interlock protection device

The function of the crane interlocking protection device: the door of the bridge crane and the gantry crane and the hatch door of the bridge frame from the driver's cab, when the door is opened, the travelling mechanism of the crane cannot be started. When the driver's cab is set in the moving part, when the door of the passage into the driver's cab is opened, the running mechanism cannot be started.

11. Sliding line indicator light

The function of sliding line indicator light: it can intuitively display whether the sliding line has electricity, which is beneficial to the maintenance and troubleshooting of the crane.

12. Buffer

Crane buffer function: It should have good performance of absorbing the energy of the moving mechanism and reducing the impact. Application: On overhead cranes and gantry cranes LT, CT running mechanisms or rail ends.

13. Rail clamps, anchoring devices, iron shoes

Function of crane rail clamps: For cranes that work in the open air on the rail, the rail clamps, anchoring devices or iron shoes should be able to independently withstand the maximum wind force under non-working conditions without being blown.

14. Wind speed and wind level alarm

Crane anemometer function: cranes working in the open air can send an alarm signal when the wind is greater than level 6 and have the ability to display the instantaneous wind speed and wind level. Cranes working in coastal areas can be set to issue an alarm signal when the wind force is greater than level 7.

15. The function of the maintenance cage: it is used for the maintenance of the conductive sliding wire in the high altitude, and its reliability should not be lower than that of the driver's cab. Application: Bridge crane is close to the side of the sliding line.

16. The function of the sweeping plate and the support frame: to prevent foreign objects from entering under the wheels of the cart and cause the crane to derail, and when the axle is broken, the wheel rolls out and hurts people. The distance between the sweeping plate and the rail surface should not be greater than 10mm, the distance between the support frame and the rail surface should not be greater than 20mm, and the distance from the rail surface should not be greater than 10mm when the two are combined.

17. The function of the rail end stop: prevent the crane from derailing. Application: bridge crane, gantry crane, tower crane, portal crane.

18. Rainproof cover for electrical equipment. The electrical equipment of various cranes working in the open air should be equipped with a rainproof cover.

The above crane safety protection devices are all important accessories to protect the safe operation of cranes, but these protection devices of cranes can only be used for prevention, or play a certain role in emergency situations. The most important factor in reducing crane safety accidents is to rely on the safe and standardized operation of crane workers during operation.
