Different Types of Soil Compaction Equipment: Types of Rollers

Pneumatic rollers have wheels on both axles. These wheels are staggered for compaction of soil layers with uniform pressure throughout the width of the roller. The factors which affects the degree of compaction are tyre inflation pressure and the area of the contact. The latest rollers have an arrangement to inflate the tyre to the desired ...

Pneumatic Tired Rollers BW24RH / BW27RH

Pneumatic tired models provide maximum versatility n KNEADING EFFECT: Rubber tired rollers produce a unique compaction effect through the kneading action of the wheels.

Tube tools, tube expanders for heat exchangers and boilers

If the beading roller expander is set so full expansion is accomplished before the bead has been formed, it will not be possible to complete a proper bead without further expansion of the tube. The tool operates such that, once the beading roll has encountered the end of the tube, the entire inward force of the tool is available to form the bead.
