A powered rope ascender that supports a person or a load while ascending a vertical rope. The rope ascender has a motor driven capstan drum that engages the rope. A pinch roller grips the rope against the capstan drum. A load limiting assembly releases the grip by the pinch roller when the load supported by the ascender exceeds a predetermined amount. A centrifugal clutch reduces starting torque required by the motor and the outer drum of the centrifugal clutch interacts with a brake to hold position on the rope. For heavy loads a motion activated brake is used. Hand controls provide a freewheeling, a braking and an ascending mode of operation. A harmonic drive or planetary reduction gears provide speed reduction from the motor to the capstan drum. The powered rope ascender can be threaded on the rope without access to a rope end.

The invention relates to a soluble fixed soft abrasive-polishing film, which comprises an abrasive layer and a substrate layer and has the thickness of 0.3 to 5mm. A soluble high-molecular material is used as a bonding agent of the abrasive layer, and a certain proportion of multilayer particle-diameter soft microfine abrasives are distributed and coated on the elastic substrate according to a certain rule. Small-particle-diameter abrasive particles not only can directly participate in a polishing process, but also can be used as a filling material and achieves the effect of supporting large particles, so that the content of a resin bonding agent in the polishing film is decreased, and the problems of film surface cracking and breakage are effectively solved. A specific nonpoisonous and harmless aqueous solvent is adopted in the machining process to solve the bonding agent on the surface layer of the polishing film, so that the holding force of he bonding agent for the abrasive particles is decreased to enable the bonding agent to fall off; on one hand, the passivated abrasive particles on the surface layer can be removed, so that the polishing film has more lasting polishing performance; on the other hand, the abrasive particles which are fixed on the surface of the polishing film and the abrasive particles which fall off and are dispersed into a polishing solution jointly act on a workpiece, so that the ultra-smooth high-efficiency surface polishing of the workpiece can be realized.
