Like general Automatic Sliding Door operators, Ningbo GDoor Automatic Curved Sliding Door operators have supporting beams, running carriage sets, idle pulleys, back up battery, electronic mechanical locks, switches, etc.. The only difference is that automatic curved sliding door operators have curved supporting beams. And the interlock system for opening and closing achieves access control and energy saving. Interlock function upgrades the automatic curved sliding door into a security portal by a sophisticated coordination system of switches and sensors. And the double ID authentication and the video analysis system prevent forced accesses.

Measure the diameter data of both sides of the misplaced position and the yaw data of both sides. The yaw value of the maximum yaw position can be subtracted from the abrasion value at the minimum diameter, and the difference is the actual abrasion amount. For example, the minimum diameter of the misalignment is 0.40 mm, the maximum value of the yaw is 0.30 mm, and the actual amount of grinding is 0.40 - 0.30 = 0.10 mm. Less, burns are likely to occur during grinding, causing scrap. In the deep part of the knife mark, it is best to use a guillotine knife to cut the symmetrical point (the most serious and most biased part) out of the two symmetrical facets before the grinding, and measure the smashed part. If the measured diameter minus the diameter of the tool mark is less than 0.20 mm, it should be grinded after the request.
The hoisting technology of small cranes can be divided into two modes: split hoisting and integral hoisting. Small cranes should be able to judge whether grinding can be performed based on the data such as workpiece bending, yaw, misalignment, and depth of tool marks. For places where the amount of grinding is not more than 0.50 mm, the operator can carefully measure the values ​​of yawing, bending, misalignment, and tool marks. For workpieces with a grinding amount below 0.20 mm, be sure to ask the person concerned for approval before grinding. If the yaw or bending amount exceeds one-third of the grinding point, it should be straightened and then ground.
In special occasions, the protective device for small cranes should also have special barriers, isolation, sealing, absorption or shielding effects on electricity, fire, explosives, high temperature, vibration, dust, smoke, radiation, and noise. Prevents any part of the human body from entering the machine's danger zone and touches various moving parts; prevents blowout of flying objects, accidental ejection of high-pressure liquid, or prevents human body from burning, corrosion, etc.; containment acceptance may be caused by mechanical throwing, dropping, launching Parts and their damaged fragments.
Lifting rod protection method for small crane
With the development of small cranes, the lifting range continues to increase, so the technical requirements for small cranes will increase. From the lifting capacity of lifting equipment, with the continuous improvement of lifting capacity of lifting equipment, the main development trend of lifting technology is getting closer and closer to the overall lifting has been gradually used in large lifting projects.
