Also known as an overhead crane, a lightweight crane is a type of lifting equipment that reduces its weight through optimized design and the use of advanced materials while maintaining or improving performance.

[0003] The existing Chinese patent with publication number "CN218290236U" discloses a new type of turntable structure for a folding arm truck crane. The device can replenish lubricating oil into the device through the oil inlet hole. The lubricating oil is immersed in the brush. The turntable rotates, causing the brush to rotate with it. The gears in the device can be lubricated by the brush.

[0004] However, when injecting lubricating oil into the device, the staff has no way of knowing the amount of lubricating oil injected, which may result in excessive lubricating oil overflowing and causing lubricating oil waste, or insufficient lubricating oil being injected, resulting in the gears not getting enough lubricating oil when the device is working, causing gear wear and reducing the service life of the device.
