ZMH1108 PLC Electro Hydraulic Trainer Teaching Equipment

ZMH2107 Double Sides Proportional Hydraulic Trainer Hydraulic Bench

I.Introduction

I‘s suitable for schools, engineer training centers, factory training department etc.

Through this trainer, students can master hydraulic components structure, hydraulic circuit control theory, hydraulic circuit design, and hand on ability for hydraulic trainer.

This trainer is flexible and students can design their own hydraulic circuit.
