Industrial conveyors are horizontal, inclined, declined, or vertical machinery that transports bulk materials or discrete units from one place to another at a controlled rate.
Lifting jacks are used for leveling or positioning heavy equipment, or for supporting structures. They use screw or cylinder-based actuators and are powered by hydraulic, mechanical, electric, or manual methods.
Wheels are solid discs or rigid circular rings that attach to assemblies such as casters to allow movement. They are connected to a hub and designed to turn around an axle.
