Chain Hoist Extension Arm

Over-the-Jeep Gantry Lift Table with Chain Hoist Extension Arm

Wished to have an ARM to extended out from my ‘Over-the-Jeep’ table whereby I could attach a small chain hoist to lift those pesky 100 to 300 pound items from the floor (or from a trailer) onto my large work table.

For my Birthday Cora, Ari, Jen, and Bryan gave me a Gift-Card for Home Depot so I decided to use it to purchase online a Speedway 1-Ton Chain Hoist.

The next step was to use the existing SolidWorks CAD designs for the Gantry Hoist Table to create additional designs for the Chain Hoist Extension Arm.

Used SolidWorks CAD Software to Create the Designs & Renderings

Went out to the Workshop and measured how far the Arm needed to extend.

The goal of the Chain Hoist Extension Arm was for it to be able to swing around from the middle of the large tabletop all the way around to a lower workbench I have behind the Gantry Lift Table.

SolidWorks CAD Software allowed me to check the ‘Range-of-Motion’ of the Chain Hoist Extension Arm and design parts for a Swivel Mount and Arm.

SolidWorks motion simulations viewed on the computer monitor gave me the ability to make sure the Extension Arm design would clear all existing items on the Gantry Hoist such as the upper welding curtain brackets.

To add  more mobility to the Extension Arm I designed a Rolling Trolley which allows the chain hoist to roll up and down the length of the arm.

There is an End Stop (Painted Yellow in Rendering)  to keep the Trolley from rolling off the end of the arm; as-well-as, holes drilled along the length of the metal to lock the Trolley in a specific location on the Extension Arm.

Extension Arm can be bolted to many areas on the side of the Gantry Table.

Once the Concept Designs were finished used SolidWorks to print out PDF Dimension Drawings and emailed them to my iPad for viewing in the Workshop.

Attempted to re-use mostly ‘Scrap Metal’ found in shop in the design …

Used As Much Scrap Metal in the Project as I Could Find

As usual, I tried to use Scrap Metal found in the shop as part of the design

Since the drawings are just for me, I try to keep them as simple as possible; however, I certainly don’t mind being redundant when marking the dimensions for parts because I feel it lessens the chance of a mistake.

The first step was to use the metal lathe to clean off and cut some scrap steel round-stock to the correct dimensions for the Trolley Wheels.

Also used the same Round-Stock to create a Swivel Hinge for the Arm …

To speed up the process after machining the wheels on the Metal Lathe, I would then cut them off in the band-saw and put them back in the Lathe to clean up.

Also bored a hole in the center of the Trolley Wheels for a 1/2″ Bolt …

While cutting the Trolley parts also cut the parts for the Extension Arm.

It was over 100 degrees in the shop the day I cut the metal so decided to print out the PDF drawings instead of viewing them on the iPad due to the heat.

When not in use the chains from the hoist are wrapped around the Extension Arm and it swings over the tabletop for storage until needed.

This Extension Arm is only for items up to 300 pounds; however, I feel it is all the lighter 100 to 150 pound items it will lift that will save my back.

— UPDATE —

The Chain Hoist Extension Arm lifting unit has been very helpful!!  

Used the unit to lift and swivel a 110 pound 22HP engine onto my tabletop …

Used Extension Arm to put the Engine of my Large Workshop Table

Just today lifted up a 140 pound small hydraulic power unit from the floor about 14 inches to put it on my Small Workshop Lift Table.

My small lift table doesn’t go all the way to the floor; therefore, the first 6″ of lifting can be very hard on a person’s back, even something only 140 pounds…
So I just lowered the lift table to about 14″ off the ground and lifted the Hydraulic Unit up and wheeled my little table under it.

Now I can raise or lower it to a good height while working on different items, once again saving my back by not having to hunch over work on the floor.

The Chain Hoist was very helpful to carefully open the Hydraulic Pumping Unit top ~ Raised it and let it drip off in tank before repairing the unit.

Also purchased an inexpensive Digital Hanging Scale

While this old motor could be set on the floor scale … It is the heavier ‘Tippy’ items that I feel the Chain Hoist Extension Arm & the Digital Hanging Scale will be very helpful with in the future.

… And YES … they sent the Bonus Free Apple Peeler!!  *LAUGHING*

The Apple Peeler was Included as Promised *grin*

  1. Wonderful bench and extension. I am moving part of my shop to the farm and will be building a bench like that. LOVE it. do you have plans for the bench itself as well? Thanks for taking the time to post this great project.
    Trusting HIM,
    Steve doveknives@aol.com

  2. Hello. excellent job. I did not imagine this. This is a excellent story. Thanks!

  3. Details about chain hoist! Great post, hope for your next post!
