Description

Technical Field

[0001] This utility model relates to the technical field of stable hoisting devices, specifically a stable hoisting device for large workpieces. Background Technology

[0002] A large workpiece stabilizing hoisting device is a piece of equipment used for transporting and installing heavy or large workpieces, widely used in construction, manufacturing, shipbuilding, and petrochemical industries. The main purpose of this type of device is to ensure the stability and safety of the workpiece during hoisting, preventing accidental tilting or falling. A large workpiece stabilizing hoisting device has several characteristics:

[0003] High load capacity: Designed to support and lift heavy workpieces, ensuring stability even under extreme conditions;

[0004] Multi-point hoisting: Multi-point hoisting is usually used to distribute the weight through multiple hoisting points, reduce local stress, and improve hoisting safety;

The equipment has low flexibility of use, and it cannot provide anti-sway protection when hoisting and moving large workpieces. The swaying of materials during hoisting can easily cause injury to workers, and the unstable hoisting of the equipment often troubles users. Utility Model Content
