FullSharp · since 1991

FullSharp installed a PLC-controlled manipulator with a clamp head that wraps around chemical drums, which can crack and leak if set down hard. As the drum nears the floor the PLC switches to ultra-slow lowering, so it lands gently and the operator has time to position it, the step where tired workers used to drop drums.

Chemical drums cannot withstand impact or being set down hard, since even a small crack can cause a leak. When carried by hand, the final moment of setting the drum down is when workers are already tired and most likely to drop it suddenly.

FullSharp installed a PLC-controlled manipulator with a clamping head that wraps around the drum body. The PLC manages the speed, so as the drum nears the floor, the unit switches to ultra-slow lowering mode, setting it down gently and giving the operator time to position it precisely.

PLC-Controlled Manipulator Clamps Chemical Drums with Ultra-Slow Lowering

PLC-controlled manipulator clamping and lowering a chemical drum into position.

Equipment Installed

  • Manipulator arm: rigid structure keeping the drum steady at any height, operated with minimal hand force.
  • PLC controller: programs lifting and lowering speed stages, automatically switching to slow speed at the end of the stroke.
  • Chemical drum clamp head: jaws wrap around the drum body, with preset clamping force that holds firmly without denting the shell.
  • Stroke sensor: detects the drum's height to trigger slow-lowering mode at the right moment.
  • Safety valve and lock: holds the load in place if power is lost, releasing the clamp only once the drum is standing steady.

Benefits for the Plant

Gentle set-down

The final lowering stage is very slow, so the drum base touches the floor lightly with no jolt.

Lower leak risk

The drum stays firmly clamped and impact-free, reducing the risk of cracks in the shell.

Consistent, repeatable operation

The PLC keeps to a single lifting and lowering sequence every shift, independent of individual worker skill.

Frequently asked questions

How does ultra-slow lowering work on a manipulator?

A stroke sensor detects the drum's height and the PLC switches to slow speed at the end of the stroke, so the drum base touches the floor lightly.

Will the clamp dent the drum?

The jaws wrap around the drum body with preset clamping force that holds firmly without denting the shell. FullSharp sets it to the real drum type.

What happens if power is lost?

A safety valve and lock hold the load in place if power is lost, and the clamp releases only once the drum is standing steady, which lowers the risk of a sudden drop.
