A hot stick for manipulating a probe from a position a selected distance away from a workpiece, the tool including an arm, a connector coupled to the arm, the connector including a connector body having a contoured first surface, and a mechanism movable relative to the connector body and configured to cooperate with the first surface of the body to retain a probe.

An assembly for controlling a vertically extending member includes a device having a stop member and a speed control member for controlling movement of the vertically extending member such as an elevator load bearing member during a roping procedure. In a disclosed example, the stop member is biased into a stop position where the vertically extending member is locked between a brake pad and a guiding member so that the vertically extending member cannot move relative to the device. An example input member for moving the stop member out of the stop position comprises a foot pedal that can be manipulated to control a position of the stop member. Absent manual manipulation of the input member, the stop member prevents movement of the vertically extending member. In a disclosed example, a speed control member comprises a pad that selectively engages a vertically extending member responsive to manual manipulation of a handle for moving the pad relative to a base of the device.

An assembly for controlling a vertically extending member includes a device () having a stop member () and a speed control member () for controlling movement of the vertically extending member such as an elevator load bearing member () during a roping procedure. In a disclosed example, the stop member () is biased into a stop position where the vertically extending member () is locked between a brake pad () and a guiding member () so that the vertically extending member () cannot move relative to the device (). An example input member for moving the stop member () out of the stop position comprises a foot pedal () that can be manipulated to control a position of the stop member (). Absent manual manipulation of the input member, the stop member () prevents movement of the vertically extending member (). In a disclosed example, a speed control member () comprises a pad () that selectively engages a vertically extending member () responsive to manual manipulation of a handle () for moving the pad () relative to a base () of the device ().

A clamp device () includes a plurality of arms (). One of the arms supports a securing member (). The other arm includes a curvilinear surface () that directly engages a curved wall of an article at a location in line with a centerline of the securing member. The curvilinear surface () allows for the clamp device to reliably engage an article having a curved wall for a lifting operation. One example use of a disclosed example device is for lifting tubes associated with a hydraulic elevator system.

A device () useful for working on an escalator () provides a tread surface () that is obliquely oriented relative to an incline (I) of the escalator () during a maintenance or repair procedure. A disclosed example is useful for spanning at least a portion of an escalator () where the normal operating steps () have been removed for purposes of working on the escalator (). A disclosed example includes a tread surface (), a riser portion () that is at least partially generally perpendicular to the tread surface (), a first axle hook () and a second axle hook (). The axle hooks rest upon spaced axles () associated with the escalator for positioning a temporary step () as desired for facilitating working on the escalator.
