Round Metal Block Clamping, Mobile Pneumatic Jib

FullSharp built a pneumatic jib crane on a mobile base with a height-adjustable column and a clamp that wraps round metal blocks, for a machining shop whose lifting point changes with each order. The jaws grip both sides of the curved surface so the workpiece does not spin as it does on a cable, and the unit is wheeled to whichever machine needs it.

Round metal blocks are heavy and slippery, giving hands no grip point, while slinging them with cables lets the workpiece spin while suspended. The machining location also changes with each order, so a fixed crane does not fit.

Equipment Installed

Mobile base: a base frame with wheels and outriggers, moved to the lifting location then locked in place.
Adjustable column: changes the arm height to match the machine and the workpiece height.
Pneumatic swing arm: raises and lowers using air, swinging gently to position the workpiece precisely at the fixture.
Round metal block clamp tool: jaws that wrap around the workpiece's curved surface, with an air cylinder holding steady clamping force.

Benefits for the Plant

Goes anywhere

The mobile base lets one unit serve multiple machines and fixture locations.

No spinning workpiece

The clamp tool wraps both sides of the round block, keeping its orientation steady throughout the lift.

Adjusts to the right height

The adjustable column keeps the arm at the correct height for whichever machine is in use.

Frequently asked questions

How do you lift round metal blocks without them spinning?

Cables let a round workpiece spin while suspended. A clamp with jaws that wrap the curved surface holds both sides with steady air-cylinder force, so the orientation stays fixed throughout the lift.

Why use a height-adjustable column?

Machines and fixtures sit at different heights. The adjustable column keeps the arm at the correct height for whichever machine is in use.

Can one crane serve several machines?

Yes. The mobile base has wheels and outriggers, so it is moved to the lifting location and locked in place, serving multiple machines and fixture locations.
