| Story PatientLift created by Michael Newman |
A patient lift was designed and built to enhance the capabilities at Wildstar Farm for Horse Senseability clients. This story shows the development of that lift and photos as it is being constructed.

This is the original concept for how the patient lift will work. The style shown is called a Jib Crane, a central post supports and arm from which the load hangs.
This is the final CAD design. This design was created in Solidworks and was used to make the metal parts, most of what is shown in grey. The electric winch hanging from the top is a commercial P-440 Portable Ceiling Lift intended for moving patients from chairs to beds etc.
The Patient Lift will allow a person to be lifted over a horse and lowered onto the horse. The horse will stand just right of this platform and the crane post will be just beyond and around the corner to the left of the platform.
Mike at the milling machine making holes for bearings in the post.
The hole shown here will get a bearing. This cylinder sits on top of the main post and rotates.
Here Will Thorn is welding the attach point for the boom to the swivel top of the crane section.
This is the top bracket for a diagonal that will support the load bearing arm. You can see the arm tied with rope in the background.
This is the load bearing arm with a mounting point for a diagonal brace showing in the middle.
Here you see the completed top of the crane. The rope gets replaced with a steel brace. The trolley that the patient hangs below is visible on the arm just left of the rope. The cylinder you see here sits on top of the main post and rotates. The patient can be moved out and in as well as around the post.
Here are the trolley, the completed arm, brace and top cylinder for the Patient Lift. On the wooden mounting block you see the sling and the motor that lifts the patient up and down.
Removing the boarding platform so work can be done beneath it.
Jacking up the ramp so the old footing can be removed and a new footing cast in its place.
Mike ready to pull the old footing out of the hole.
Chain ready to pull old footing for ramp out of the hole. The post and the ramp will be supported by a new footing.
Cement mixer at post hole. Footing got poured this day.
Lowering the Pole into the hole.
Inserting the pole into the foundation hole.
The rebar cages at the base of the pole will be lifted up once the pole is in position.
A new to us aerial lift being used as a crane to lower the pole into the foundation hole.
This foot plate will sit on top of the concrete foundation helping hold the pole in place and providing a hard point for the ramp to sit on. The pole will eventually go under the arc cut in the wood at the left of this photo and the plate will be rotated under the post at the very left edge.
Part of the concrete foundation is poured. Some of the rebar cages are visible. The plate at the top has been rotated into position. J-bolts can be seen hanging from the plate. These will be embedded in concrete.
Concrete is finished. The concrete holding the pole must now be allowed to set for a few days before the top of the crane can be assembled on it.
