A brake assembly for a retractable wheel mechanism for boat lifts and docks can include a contact plate, an axle insert and a brake. The contact plate can include an aperture therethrough so that the contact plate can be disposed on an axle about which a tire rotates. The axle insert can be sized and shaped to fit into a hollow portion of the axle. The brake can be configured to be pivotally secured to the axle insert such that the brake cannot rotate about a rotational axis of the tire while still allowing the brake to pivot perpendicular to a rotational axis of the tire. The brake member can be pivoted from an engaged position that prevents the tire from fully rotating to a disengaged position where the tire can freely rotate.

The invention relates to a device for the stable and zero backlash adjustment of a camera-holding device around at least one tilting axis, in particular on a device for multi-channel image capture, wherein the adjustment device (1) comprises two plates joined to one another so as to be tiltable, and wherein the upper plate as camera support plate (2) carries the camera (K) at least indirectly and is connected to the lower plate acting as base plate (3). The device is characterised in that a displaceable ramp slide (5) having two oppositely inclined running ramps (6) is arranged on the base plate (3), in that between the two running ramps (6) there is a joint (4) by which the camera support plate (2) is joined to the base plate (3), in that the camera support plate (2) comprises two guide pins (7) that are spaced apart from one another and are guided on the running ramps (6), and in that the device is designed in such a manner that by displacing the ramp slide (5) the camera support plate (2) assumes, with zero backlash, a defined tilting angle with respect to the base plate (3).

A step assembly includes a horizontally extending mounting foot section, a vertically extending head section, a single sloping support member interconnecting the mounting foot section and head section, and a step member having a number of integrally formed horizontal steps extending above and attached to the single sloping support member. The step assembly is narrow in a width dimension for use on a narrow dock section, and the horizontal steps are configured to facilitate personal access to a raised boat on a lift.
