Description

Technical Field

[0001] This utility model relates to the field of stacker cylinder technology, specifically a stacker rotary lock cylinder. Background Technology

[0002] A stacker is a type of machinery commonly used in warehousing and logistics, primarily for handling, stacking, and unloading goods. It is typically used for efficient material stacking and retrieval within limited spaces, especially suitable for goods requiring high storage levels. Stackers are flexible in operation and suitable for stacking and organizing goods in warehouses, factories, ports, and other similar locations. Stackers utilize a hydraulic system to raise and lower goods. Electric stackers use an electric motor to drive a hydraulic pump, generating hydraulic pressure that pushes a piston rod in the cylinder, thereby raising or lowering the forks. Operators can control the stacker's forward, backward, lifting, and steering operations via a control panel or handle. As an essential piece of equipment in modern warehousing and logistics, stackers are widely used in various applications due to their high efficiency, flexibility, and safety. With technological advancements, progress in intelligent and energy-efficient stackers will further enhance their role in material handling.

[0003] The existing technology has the following problems:

[0004] Existing forklift cylinders have a relatively simple overall structure and limited functionality. They generally only have telescopic and push-pull functions and lack a safety braking and locking mechanism. During operation, the cylinders are prone to accidents due to accidental unloading or pressure fluctuations, which can cause the hydraulic system to go out of control and lead to safety issues. This makes it inconvenient to use them safely. Utility Model Content
