Yale AYS Piston Plates for YS Hydraulic Cylinders ? Ground Protection & Load Distribution

Description

Yale AYS Piston Plates are designed to improve stability, safety and load distribution when using Yale YS-series hydraulic cylinders, particularly on uneven or soft ground or when used with accessories such as lifting claws. By increasing the contact area between the piston and the supporting surface, piston plates help prevent sinking, tilting and surface damage during lifting operations.

The plates screw directly into the piston thread of YS hydraulic cylinders, creating a secure interface that spreads load more evenly across concrete, asphalt, soil and other surfaces. This is especially important in high-load applications where point loading could cause surface deformation or instability.

When used with AYS lifting claws, piston plates play a critical role in maintaining system stability by safely distributing reaction forces into the ground. This helps reduce uneven loading, piston misalignment and the risk of movement during lifting.

Manufactured from robust steel, AYS piston plates are built for repeated use in industrial, construction and maintenance environments. Available for multiple YS cylinder capacities, they ensure correct sizing, improved lifting accuracy and extended service life of both the cylinder and supporting surface.

Typical applications include container lifting, machinery installation, steel erection, structural alignment and maintenance work where ground protection and stability are essential.
