QY type pre-tightening elevator vertical hanging steel plate clamp
QY type pre-tensioned elevator is a type of elevator specially developed for lifting, overturning and assembly of steel structure parts. QY type pre-tensioned elevator is provided with a pre-tensioning device.
Before lifting, the pressure angle exerts a certain pre-tensioning force on the workpiece under the action of the spring; during the lifting process, as the load increases, the clamping force increases, ensuring safe and reliable lifting.
This type of big ship crane is used for operation. The suspended object can be moved vertically or horizontally without changing the state, and the workpiece can be flipped, which is especially suitable for assembly and use.
