Abstract: A counterweight slack detection switch including a body, a first belt guide mounted to the body and configured to engage a first side of a tension member, a second belt guide mounted to the body and configured to engage the first side of the tension member, a lever arm having a first end and a second end, the first end pivotally mounted to the body, a deflectable member biasing the lever arm relative to the body, a third belt guide mounted to the second end of the lever arm and configured to bias the tension member from a tension position to a slack position, and a switch mounted to the body and configured to contact the tension member when the tension member is in at least one of the tension position and the slack position.

Abstract: An installation tool configured to install a machine of an elevator system, including a base section including two legs, each leg including a laterally extending gusset attached thereto. A clamp assembly is supported by the base section and includes a first bracket attached to and positioned over the two legs and a second bracket attached to and positioned over the gussets. A first tube is movably carried by the first bracket and a second tube is movably carried by the second bracket. The first and second tubes are movable in the brackets between a retracted position that positions the machine over the base section and an extended position that positions the machine in a cantilevered position adjacent the retracted position.

Abstract: A shifter assembly configurable for multiple automatic vehicle transmissions comprises a housing, a base mounted within the housing, a shift handle pivoted to the base, and first and second gate plates selectively mountable to the base in differing configurations cooperatively forming differing shift gates for differing gear shift patterns adapted to differing automatic vehicle transmissions for reverse or forward shift patterns. The base, handle, and gate plates are selectively mountable as a unit within the housing in differing orientations relative to a cable-receiving opening in the housing to facilitate installation within a vehicle with the cable extending from the housing in either a forward or a rearward direction.
