1/87th Prentice Knuckleboom Loader

This is a representation of the Prentice 2124 type log loading boom that can be mounted on either  a trailer, truck, or straight truck, with an approximate reach of 22 feet. The grapple can swivel and rotate, but will require patience and attention to the pictures in the desription that shows the expanded version. The boom will rotate, and raise/lower as well as the outrigger stabilizers will extend.  There are a lot of pins involved in order to make operational, but 3d materials that print for this are inherently weak, so please, whenever possible, replace with wire, styrene, brass or any other material.  Should there be a question or conern, contact me via the designer link or direct via email to modelmechanic@gmail.com 
NOTE! There are two hydraulic cylinders....the one that is longer is the 'main' cylinder that attaches to the base and the boom. The shorter attaches from boom to stick. Please check the photos for orientation...that'll make your life easier.
