Use it with the Ioptron GEM45, Ioptron pier and Stellarvue 102 for astrophotograpy. I ordered the one with the 10" wheels. It works great to move the scope from the garage to the back yard over uneven terrain. Only complain is that the pulling handle is about a foot too short. I am 6 feet tall and have to bend over to pull this thing. A little longer pulling bar would have been great. I added a short piece of rope so I can pull the unit with a straight back. Instructions are not very clear either. It is well build and strong enough for a heavier mount and scope.
One star deduction for the short handle bar. Not everyone is 5 feet.

Hot Wheels

I fitted my old Meade LX50 10” SCT onto the dolly, upgraded the leveling screws, added a battery shelf and a tow handle and I can just wheel her out and wheel her back in when I’m done. Should have done it sooner.

Great product and service

After I ordered online I was contacted to make sure I ordered the correct size Wheeley Bar as well as accompanying accessories. I was glad they did, as I decided to make some changes. The Wheeley Bar is exceptionally well made and easy to assemble.

Excellent product

My C8/Atlas Pro astrophoto mount lives in garage, rolls to driveway for use. Previously used moving dollys. Benefits of JMI Dolly: no lifting, easier leveling, more secure/reliable/durable, moves much more smoothly...does not jar mount.

Wheeley Bar Dolly for Losmandy G-11

I’m very impressed with the Dolly! Excellent design, construction and components. It’s carefully packed and arrived in excellent condition in short order from California to New York. The Farpoint staff took a very active role to be sure the order details were correct and would suit my needs. Assembly was straightforward with a few simple tools. The Dolly is a perfect fit for my older style non-folding G-11 tripod- very solid support. Cloudy weather has prevented me from getting outside with it yet but I look forward to doing so soon.

JMI HEAVY-DUTY Medium Size Universal Wheeley Bar Telescope Dolly

All Medium Heavy Duty Wheeley Bars fit tripod tip-to-tip distance of 34 - 42.5 inches

Maximum Load: 300 lbs

Tip receptacle is 2-3/4″ I.D. Will not fit tripods with feet larger than 2-3/4 inches.

The 2 3/8" wheels and 1/2" leveling screws are no longer available on the Medium Heavy Duty Wheeley Bars. The Standard Package now comes with 5" Wheels and the Heavy Duty 5/8" Leveling Screws.

These new style Medium Heavy Duty Wheeley Bars now fit the Losmandy HD Tripod Gen2 (tubular design) for G-8 or G11 mounts. The old Losmandy specific Wheeley Bars have been discontinued.

See doorway measurements for more dimensions and fitting through a door.

JMI HEAVY-DUTY Medium Size Universal Wheeley Bar Telescope Dolly is a portable dolly for your telescope.

Constructed of a sturdy base with locking wheels and leveling bolts, the heavy-duty version is designed with heavier telescopes in mind. Save your back! Our Wheeley Bars create an easier and faster way to move mounted telescopes to and from observing locations.

Easily move, lock and level the complete telescope assembly from location to location without the need to disconnect and reconnect all the electrical and computer cabling during transport. Standard equipment includes Heavy Duty 5/8" Leveling Screws.

This HEAVY-DUTY Version is designed for heavier equipment with the same footprint as the standard Medium Wheeley Bars but with stronger, heavier-duty construction. Because of the increased weight with the same base width, there will be a greater risk of toppling over due to the high center of gravity. To prevent damage from falling over, the equipment will need to be strapped down to the Wheeley Bars. As with all Wheeley Bars, JMI will not be responsible for equipment tipping over.

What is Tip-to-Tip Distance?

To be sure that your tripod or pier will fit a particular Wheeley Bar product, it may be necessary to verify the tip-to-tip distance of the mount.

Choose your Wheely Bar model based on tip to tip distance. To measure that, setup your telescope at observing height...not all the way up or down, but at the height that gives a comfortable eyepiece height. Remember to make allowance for the height of the Wheeley Bars. Please keep in mind that the 5" wheel set raises the setup about 6"; the 10" wheel set raises the setup about 3.5". So the procedure is:

1. Setup your tripod at observing height

2. Lower your tripod 6 inches if you are getting the 5" polyurethane wheels. Lower your tripod 3.5 inches if you are getting the 10" pneumatic wheels.

3. NOW measure the distance between two tripod tips. This is the distance you should use to choose between the HD Medium or the HD Large Wheeley Bars, etc.

Doorway Measurements

We often get questions regarding the width of our Wheeley Bars to determine if they will fit through a particular doorway. The following information should help in making that determination.

The following dimensions do not apply to Wheeley Bars that have been upgraded with 10" large wheels. For Universal Wheeley Bars with the 10" Large Wheel Upgrade the doorway width must be three (3) inches wider than the tip-to-tip distance.

There are three basic measurements as noted above.
    • The maximum width (X) is measured in a similar fashion as the tip-to-tip distance except that the measurement is made to the outside corner of the legs or leveling screws (typically about 3" wider than the tip-to-tip measurement of a pointed tip tripod mount).
    • The minimum measurement (N) is from the end of one leg to the inside measurement on the opposite side. This would help in determining the narrowest door that the Wheeley Bars could possibly be maneuvered through.
    • A third measurement (W) is in between the other two and gives the width as measured from the end of one leg to the outside measurement of the opposite side.
The illustration on the left shows the Universal Wheeley Bars turned so they can be pushed through the doorway based on the NORMAL width (W) without having to do any special maneuvering.

The second illustration shows the Universal Wheeley Bars being maneuvered by twisting them through the doorway based on the absolute MINIMUM dimension (N).

The third illustration shows the Wheeley Bars being blocked from moving though a doorway because they are positioned such that the MAXIMUM profile (X) is being presented.

Universal Wheeley Bars are called Universal because they are made to be adjustable to handle various sizes of mounts. This means that the measurement we have been talking about can vary depending on the in-out adjustment of the Wheeley Bar legs. The table below shows the minimum and maximum for the different widths indicated by the variable W, N and X.

What Size Wheels Should I Purchase?

For hard surfaces, such as concrete sidewalks, with seams or cracks, the 5″ polyurethane wheels are best.

The large 10″ all-terrain pneumatic rubber-tire wheels are designed for field use on rough surfaces such as grass, dirt and gravel. However, great care must be taken in maneuvering on these surfaces, particularly when wet, because the wheels may sink below the surface.

We do not recommend using Wheeley Bars on these surfaces under adverse conditions, especially if you have a very heavy telescope.
