A system for cleaning and conditioning handrails. A cleaning pad is curved to approximate the shape of a handrail, and is disposed on an arm. The arm may be mounted on a support structure, allowing it to be rolled up to an escalator handrail and left to do the cleaning while the escalator runs. When mounted, the arm may include a spring or piston to keep the arm in a particular position. A second cleaning pad may be included to dry or polish the handrail, the handrail going first through the cleaning pad and second through the drying pad. The arm may be hand-held, allowing a user to reach up or down steps or an incline. The cleaning pad may be mounted such that it rotates about the arm for storage, maintenance or better reach, such as around bends or corners.

Systems and methods for handrail cleaning

An incline elevator with a load carrying unit running on a U-shaped track. The load carrying unit is mounted on trucks engaging the track. Below the trucks are swivelably mounted eccentric safety devices, with roller guides spring loaded against the interior walls of the channel, and eccentric brakes retracted during normal operation or extended during emergencies like a break in the elevator hoist cable. The eccentric brakes are retracted when both mechanically and electrically driven linkages are engaged. The brakes are retracted when tension is present in the hoist cable, and when electrical speed sensors sense an underspeed condition. The eccentric brakes deploy when either there is a hoist cable break, an overspeed condition, or an incline elevator power failure. The eccentric brakes are spring loaded to swing out, engaging the interior walls of the channel of the track, and jam in position stopping the load carrying unit.
