A safety harness for an operator of a machine includes an air bladder attached to the safety harness such that the bladder is positioned between the operator and the harness. A pressure sensor is connected to the pressure sensor. A comparator circuit receives an output voltage of the pressure sensor and compares it to a reference voltage setpoint. When the safety harness is not worn by the operator the voltage output of the air pressure sensor is below the threshold reference voltage of the comparator circuit and when the safety harness is worn and tensioned the air bladder results in an increase in the output voltage from the air pressure sensor to determine whether the safety harness is being worn to switch the machine interlock when the operator is safely fastened into the harness.

Safe zone detection system for lift having a pluarlity of sensors
A safe-zone sensing system for a lift having a base, a lift platform, and a driving system for raising and lowering the lift platform. The safe-zone sensing system includes a sensor system having a plurality of sensors mounted to the base of the lift. The sensors collectively defining a safe-zone around the base of the lift and detecting motion or obstructions within the safe zone, a controller fires the sensors in a preselected sequence for continuously scanning the safe zone. Scanning is started when the platform raises above a preselected height. The sensor controller generates an alert which initiates a safety sequence when motion or obstructions are sensed by at least one of the plurality of sensors.

A novel lockstep mechanism for a rolling ladder is described. The weight-releasing ladder lockstep allows a ladder to be relocated on wheels but when a person climbs the ladder, the front wheels are automatically retracted and the ladder rests firmly with its front feet on the floor. When in the climbing (stationary) position the front wheels of the lockstep are retracted and the ladder rests on the lockstep's feet. When in the rolling position, the ladder is tilted slightly back on its rear wheels and the wheels of the lockstep are pushed down to allow the ladder to roll. When in the rolling position, the lockstep wheels are held in place via a latch which is isolated from rolling vibrations through pivoting shock links and springs.
