Universal Transloader Moves Delicate Equipment Without Stress 
- 
Spring-Loaded 
The problem: 
To move delicate or heavy items over irregular 
surfaces without transmitting stress to the load: 
The solution: 
A loader that is supported on three pivot points to 
produce a warp-free base which in turn is supported 
by an articulated four-wheel frame.
How it's done: 
The transloader is supported by four widely spaced, 
evenly loaded wheels. Two of the wheels are located 
directly under support points. Transmission of distor-
tion forces experienced by the transloader to the load's 
cradle is eliminated by the independent three-point 
support.

One side member of the trailer is free to rotate 
about the longitudinal axis of the cross member to 
insure full wheel contact over uneven terrain and thus, 
an evenly distributed load. The motive power always 
provides a direct pull due to the universal joint con-
nection to the cross member. 
The support bases of the items to be moved are 
equipped with three extension arms which mate with 
the transloader pickup points. The transloader is 
maneuvered into position around the support base 
and the ball-socket extension arms are aligned with 
the three pick-up points. The supports are raised into 
position and the load is lifted for transporting. The 
vertical travel of the support points can be independ-
ent or synchronous and can be activated by mechani-
cal, hydraulic, or electrical means. 
Once the load has been moved to its new position 
it is set down by lowering the ball-type supports on
the transloader and moving the trailer out from under 
the item's cradle or base.
