We’re committed to safety, efficiency, and injury-prevention in every workplace environment.Employer surveys show that accidents and injuries on stairs are the biggest single cause of back health and accident-related absenteeism from work in manual material handling industries. Poor posture during manual material handling on stairs or steps can cause a loss of  load control and a sudden, unpredictable increase in physical back stress. This often leads to injury and property damage. With the M3 Stair Walker your employees can maintain the natural “S” curve of the spine at all times while using a dolly on stairs. This the neutral position is the injury-free safety zone for the back.
