A boat or recreational vehicle ladder apparatus is provided. One aspect of the present ladder apparatus includes an elongated extension handle including a slot adjacent a lower end thereof. Another aspect of a boat or recreational vehicle ladder apparatus provides a snap-on step tread which can be mounted to a dual-tubular ladder step structure. Another aspect of a boat or recreational vehicle ladder apparatus employs a laterally expandable ladder step which can be retrofit onto an existing ladder. A further aspect employs clasps or hooks to attach and retain a ladder step to generally vertical ladder rails in a tool-free and fastener-free manner.

Boat or recreational vehicle ladder apparatus

A railroad wayside signal cantilever () including an arm () with a signal mounting apparatus () that provides a degree of horizontal movement of the signal () relative to the cantilever mast (). The available range of locations for securing the signal on the arm is sufficiently broad to allow a single cantilever design to be used for a wide range of site-specific locations. An extendable catwalk railing () is provided to accommodate movement of the signal without creating an unsafe gap between the railing and the signal.

Wayside signal apparatus with adjustable signal position

This invention is a railroad wayside signal system positioned adjacent to a railroad track that comprises a mast that is attached to a support structure in an upright position. A signal head having one or more signal lights is mounted to the mast such that a locomotive operator in an approaching locomotive can see the signal lights. The mast pivots with respect to the support structure between the upright position and a substantially horizontal position for maintaining and/or aligning the signal head and signal lights. The signal system may also be equipped with one or more actuators operatively connected to the signal head. A remote control unit is placed in communication with the actuators, and the remote control has an input mechanism for inputting a command representative of a direction of rotation of the signal head. The remote control also generates a signal in response to the input command that is representative of one or more directions of rotation.

Railroad wayside signal system

A control mechanism for moving switch points on a railroad track, having a drive screw driven by a motor, a traveling block moving along the drive screw to position the switch points, an end stop on the drive screw for limiting movement of the traveling block, a hand crank for manually turning the drive screw, and a torque limiting clutch on the hand crank.
