FullSharp built a column-mounted pneumatic manipulator that carries the full weight of a large Hitachi concrete drill for a steel plant, so the operator only pushes the drill into position and drills. The arm rotates 360 degrees around the column and adjusts in height, reducing arm fatigue and keeping holes straight at many points from one setup.

Large concrete drills are heavy and vibrate strongly, forcing the operator to use both arms to hold the drill steady at the exact point. Working continuously numbs the hands, the drill bit tends to wander off-center, and in a steel plant, drilling overhead or sideways makes it even harder to keep the drill steady.

FullSharp builds a column-mounted pneumatic manipulator to carry the full weight of the Hitachi drill. The operator only pushes the drill into position and drills; the arm rotates 360 degrees around the column and adjusts in height, so it can work at multiple points without being reinstalled.

Column-Mounted Pneumatic Manipulator for Hitachi Drill Support

Equipment Installed

  • Load-bearing column: fixed permanently at the work area, withstanding vibration and push force during drilling.
  • 360-degree rotating arm: swings fully around the column to cover multiple drilling points without moving the base.
  • Pneumatic assist unit: holds the drill suspended in air, staying steady at the drilling position even when the operator lets go.
  • Drill mounting bracket: grips the drill body securely and can be detached when the drill is needed elsewhere.
  • Height adjustment mechanism: raises and lowers the drill to match the drilling point, with no need for a platform or temporary scaffolding.

Key Specifications

  • Rotation Angle360 degrees

Benefits for Your Plant

Less arm fatigue

The equipment carries the drill's weight, leaving the operator to guide direction and control only.

Fewer off-center holes

The drill is held steady, keeping holes straight and reducing broken bits and rework.

Covers multiple points

Rotating around the column and adjusting height lets one setup drill many holes.

Frequently asked questions

How can I hold a heavy drill steady for long periods?

A pneumatic manipulator takes the drill's weight and much of the vibration, so the operator only guides direction and feed. Holes stay on center and hands do not go numb after a shift.

Can a drill support arm reach several drilling points?

Yes. This arm turns 360 degrees around its column and adjusts in height, so one installation drills many holes without being moved or reinstalled.

Can a manipulator be made for other heavy power tools?

The same principle works for other heavy handheld tools. FullSharp looks at the tool weight, working directions and reach, then designs the arm and tool holder to match.

Consultation for Your Plant Installation

FullSharp reviews the drill's weight, drilling direction, and the range of points to be drilled to calculate the column height and arm reach. Our engineers fabricate a mounting bracket to match your exact drill model, then install and test it on-site at your installation location.
