The PRATT Harp Dolly


We manufacture and sell a quality harp transport dolly for our Empress and Chamber Harp













Moving your Empress or Chamber harp is easy with our harp dolly, even up and down stairs.  The dolly easily and securely attaches to the harp itself—with the cover set on or off, permitting your hands to have a firm hold on your harp itself while moving it.


The great advantage to using our harp dolly over a more traditional strap-attached dolly is the safety and security of your harp.  Using the traditional kind of dolly, your hands are on the handles of the dolly, not on the harp itself, and you are obliged to trust your harp to the strap that is supposed to hold it to the dolly.  This is a disconcerting feeling to trust your harp to the ability of a buckle, or worse yet—Velcro, to keep it on the dolly.  If the strap should come loose, you have only an awkward split second to try and grab your harp and prevent it from falling.  This is especially critical on stairs.


Using our harp dolly, your hands are at all times securely holding your harp, not the dolly handles, to keep it moving where you want, and to prevent it from falling or slipping.  The rear feet of the harp rest on the shelf on the dolly, and the pin on the shelf engages a hole in a socket affixed under the rear of the harp base.  The telescoping rubber-coated steel hook then engages the middle sound hole, and is slid down as far as it will go, and the hook tightened securely with the tightening knob.


Following are some photos demonstrating use of the dolly:

The hook then passes through the hand opening in the back of the cover, and into the middle sound hole.  The hook is then slid down as far as possible, against the bottom edge of the sound hole.  The hook is then secured in position with the tightening knob.

Frequently Asked Questions about the PRATT Harp Dolly



1.  What is the price of the harp dolly?


The price of the harp dolly is $300.00.


2.  Will the harp dolly work on any PRATT Chamber Harp or Empress—even older ones?


Yes, however, The polymer socket with the hole to engage the dolly pin must be installed under the harp base.  All Chamber Harps and Empress harps have come with the socket installed when new since the dolly was first developed.  If your harp does not have the socket installed, we will provide one with the mounting hardware at no extra charge if you purchase a harp dolly.  Detailed instructions are provided describing installation of the socket and use of the dolly. (See link below.)  Installation requires drilling two 1/4” holes in the base, and then deepening the socket hole into the wood about 3/8” with a 3/4” spade bit.  For one familiar with tools, this will require about ten minutes.

3.  I want to use the harp dolly with my existing harp top cover and base cover.  What do I do with my old Chamber Harp or Empress base cover that does not have the opening in the bottom to accommodate the pin on the harp dolly?


All Chamber Harp and Empress harps and cover sets, since the development of the harp dolly, are equipped and ready to work with our harp dolly without any modification.


For harp covers produced before the design of the dolly, your existing base cover will have to be modified with an opening in the correct location to accommodate the harp dolly.  We can perform this modification for you, as well as modify the top cover to bring it up to current standards, including attaching the strap handles to the top cover.  These strap handles on the top cover (see photos of harp covers on the “Harp Covers” page) are necessary to securely hold onto the instrument while moving it.  See the “Harp Covers” page for further information and pricing on modifying harp cover sets for use with the harp dolly.

4.  Will the harp dolly work on Pratt Princessa or Debutante harps?


No, not in the basic design.  The configuration of the base for the Princessa and Debutante does not lend itself to the manner in which the dolly engages the hole in the socket under the base.  It would be possible to contrive an adapter that would engage both the rear legs of these harps and the pin on that dolly, but such an adaptor would not be able to engage the rear legs with the base cover on.  Such an adaptor would work with only the top cover on, however.  If you have a Princessa or a Debutante and are interested in using this dolly with such an adapter, please contact us.  We would be happy to work with whatever might suit your needs. 


On the other hand, the Princessa and Debutante are considerably lighter instruments than the Chamber Harp or the Empress, so a dolly would not usually be such a need for these harps.


5.  Will the Pratt harp dolly work on harps of different manufacturers?


Perhaps.  For the socket to be installed on another harp, there should be a flat area under the back underside of the base about 3/4” or so higher than the lower wooden surface of the feet.  If that is the case, then the socket might be installed on this surface.  Careful measurement should be made, however, as to the relative position of the rear feet to the socket, so that the rear feet will fit firmly on the shelf of the dolly and still permit the dolly pin to comfortably engage the socket hole.  In the event that the dolly hook is either too short or too long for one of the sound holes (unlikely), contact us for a shorter or longer hook.  The hook is made of 3/8” steel rod, with rubber tubing on the bent or “hook” end, to protect the surface of the harp sound hole. 


Note:  Some harps, particularly pedal harps, have a base attaching bolt in the vicinity of where the socket might be mounted.  So care would have to be taken in planning where the socket might go, and that it will be in a position to engage the pin from the dolly shelf. 


6.  What kind of wheels does the dolly have?


Pratt harp dollies use 10 inch diameter solid rubber tires, with ball bearings.  We resisted using pneumatic tires, as they require constant attention to keep the tires properly inflated.  It is frustrating to want to move quickly to move your instrument only to find that the dolly tires have gone low or flat.  The wheels on our dollies require no maintenance.
