Claims19
A cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once.
A cleaning device for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- an attachment plate which may be fixed to a machine casing;
- at least one L-shaped first bracket which may be adjustably fixed to the attachment plate;
- at least one L-shaped second bracket which may be adjustably fixed to the first bracket;
- and
- a cleaning head which may be fixed to the second bracket, including:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head is positioned to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once.
A method for installing a cleaning device in an elevator system, comprising:
- fixing an attachment plate and at least one L-shaped first bracket to a machine casing;
- fixing at least one L-shaped second bracket to the first bracket;
- fixing a cleaning head to the second bracket, the cleaning head including a base plate and a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
