Abstract: An engineering wood based laminated panel for use as structural flooring for vehicle decking systems replaces a traditional hardwood decking and is cheaper plus having superior structural and wear properties. The panel has a plurality of layers in order down from a top surface, comprising a surface layer (1) having at least two high density wood veneer plies oriented parallel to one side of the panel, a load distribution layer (2) having at least one high density wood veneer ply cross oriented to the one side of the panel; a core layer (3) having from about 8 to 14 wood veneer plies oriented parallel to the one side of the panel with centre plies of the core layer being high density wood plies, and a resin impregnated reinforcement layer (4).

Abstract: A sheave liner for an elevator system sheave that supports a hoist rope with an elevator car suspended therefrom is replaced without having to remove the hoist ropes and without having to hang the elevator car by means other than the hoist ropes. The existing liner is cut and removed while the elevator car is suspended from the hoist ropes resting on the sheave. The new liner is rotated into its position and two ends of the liner are joined by either a mechanical bond or by a room temperature adhesive bond.

Abstract: A cleaning device for removing sludge build-up from elevator ropes includes a brush assembly secured within a housing and shielded by a guard. The sludge is continuously removed from the elevator ropes as the elevator ropes pass through the bristles of the brush. The housing includes a removable receptacle where the removed sludge is collected. The receptacle is periodically removed and cleaned. The cleaning device also includes a cleaning bar which removes the sludge from the brush to provide more effecting cleaning of the elevator ropes.
