I am starting on an addition to my trailer. I am building
a log boom/grapple so I can self load logs on the trailer. Here is the design I
came up with. I designed this with a 3D software package from Alibre
is the trailer before I started. I have some of the steel for the project
on the bed of the trailer, and in the picture to the right the pins and
bushings that are going to be needed.
started by extending the frame out 2 1/2 feet and added another 4"
channel iron to the frame.
have reattached all the log bunks to the frame, and in the front you can
see the start of the log loader base.
am mocking up the outriggers.
have cut out the plates that will reinforce the pivots and am doing a test
have the outriggers all tacked together. All that is left is some final
welding, and run the hydraulic lines.
brother is doing most of the welding on this project. I can weld, but he
does a much better job then me. So I figured it wouldn't hurt to let him
do the final welding.
Here he is welding the pivot plates on the boom and stick.
am test fitting the boom to stick pivot.
are using a magnetic drill to drill the holes for the bushings.
have the boom to stick pivot together.
I am test fitting the swivel that the entire boom assembly will attach to.
are welding the swivel together.
on the gear that a hydraulic motor will power to swivel the boom.
is the base assembly welded to the trailer with all it's braces.
is the shaft for the bearings for the swivel. And I have installed the
shaft into the base.
installed the bearings and placed the swivel on the shaft.
lifted the boom up to the swivel with the cherry picker. Then we welded
the bushings for the pivot pin in place.
lifted up the end of the boom and installed the main lift cylinder.
then lifted the stick into place and installed it.
is the stick pivot all assembled.
then made a mount for the engine.
am starting on the grapple. On the left is one set of tines for the
grapple. And on the right is the base of the grapple and the other set of
grapple is all assembled.
is the rotator and rotator hanger for the grapple. I used a wheel
hydraulic motor to power the rotator and hang the grapple from.
is the beginnings of the oil reservoir tank.
the motor to rotate the boom has been mounted.
