| These 10" wheels and pull handle make it easy to move your assembled telescope over very rough and uneven ground. They’re an improvement in maneuverability over the 2-3/8" wheels (or even the upgraded 5" wheels) that normally come with the JMI Medium and Large Universal Wheeley Bar tripod transports if you have to move your scope over rough terrain. The standard 2-3/8" hard rubber wheels are fine for moving on smooth surfaces such as patios and driveways. The larger 5" polyurethane wheel upgrade makes it easier to move your scope across grass, dirt, and gravel, or uneven hard surfaces such as flagstone paving, as well as smooth surfaces. However, if you regularly must move your scope over very rough and uneven surfaces, or if you often travel to new dark sky sites where you’re unfamiliar with the type of terrain you might encounter, the larger wheel diameter and footprint of this six wheel set provide a margin of maneuvering ease and safety that you’ll readily appreciate. You can either specify using these wheels when you first order your Wheeley Bar (versions #WBAR10 or #BWBAR10), or you can order the wheels separately to upgrade the 2-3/8" wheels on an existing Universal Wheeley Bar. You can only replace your existing 2-3/8" wheels with these 10" wheels if the wheels on your Wheeley Bar are attached with bolts (the current method) rather than rivets (very old method). These wheels are not compatible with the #BWBARC5 Wheeley Bar for Celestron CGE mounts. Even with the larger 10" wheels in place of the 2-3/8" wheels, your telescope still is raised no more than 4" above ground level. Nevertheless, the Wheeley Bar is designed to be used with the telescope tripod legs fully retracted to keep the center of gravity low and to allow the telescope to be moved through doorways more easily. Locking wheels and leveling screws on the Wheeley Bar allow you to move, lock, and level the complete telescope assembly with ease. The six large 10" diameter pneumatic wheels are set up with two to each Wheeley Bar leg to distribute the weight of the scope evenly over three large tire footprints so as not to sink into soft ground. A dual inboard wheel design on the rear wheels maintains a narrow profile to make it easy to maneuver through doorways. The supplied pull handle locks the dual front wheels when not in use. The feature image below of the assembled 10" wheel set shows a Wheeley Bar with an optional battery pack and battery pack holder (#BPTRAY). A word of warning. Care should be used when moving the complete system, even on smooth surfaces. Be certain the tripod legs are fully and firmly inserting in the Wheeley Bar’s leg receptacles. Move the system using the pull handle. If extra help is needed in soft or particularly rough terrain, the assistant should pull or push the system only by gripping the telescope tripod below the center of gravity, particularly with a heavy scope mounted on the Wheeley Bar. Do not push the top of the scope to get it moving, particularly on uneven surfaces. Astronomics and JMI are not responsible for incorrect loading or operation.
