Knee Creepers

The Problem

  • Construction work performed at floor level often requires workers to stoop, squat or kneel for prolonged periods of time.
  • Biomechanical research shows that high compression forces occur in the spine while stooping, and that sustained or repeated flexion of the spine may decrease the stability of the lower back and increase the risk of fatigue, leaving the back more vulnerable to injury.
  • Knee osteoarthritis and discomfort are risks from the prolonged direct contact with hard surfaces while kneeling, as well as increased stress on ligaments and tendons in a squatted position.

One Solution

  • Kneeling creepers, such as Racatac and MasterRac, can be used to eliminate squatting and stooped postures and increase comfort when kneeling.
  • The padded surface on the kneeling creeper reduces the contact force on the knee compared to kneeling on hard surfaces, and improves comfort.
  • Where kneeling creepers are impractical, knee pads could be used. Knee pads distribute the body weight over a larger surface area and reduce the force on the knee caps.

How It Works

  • Workers position themselves on top of the kneeling creeper and are able to sit on the seat or kneel on the knee holders while performing tasks at floor level.
  • Some models of kneeling creepers are equipped with a chest support for the worker to lean on while working at low heights. The chest support reduces the loading on the spine while kneeling for prolonged periods of time

Benefits

  • The use of this product eliminates the need to squat while working at floor level, which reduces the likelihood of developing a knee or back injury.
  • The low profile casters allow workers to have greater mobility while staying close to the work surface.
  • The chest support on the knee creeper reduces spine loading while in the kneeling position, improving comfort and reducing muscle and joint fatigue.
  • Worker productivity may improve since mobility is enhanced and discomfort is reduced.
