Bin Jacker Supply sells, rents and rebuilds Sib Simes jacks.

Sib Simes developed his style of jacks from the government-issue Binkley dolly Jacks in the nineteen-sixties in Walters, Minnesota. Sib marketed these jacks into the early nineties. They were distinguishable by their John Deere green color, flat gearbox cover, and removable gearbox bushings. They also had Binkley machined all-steel gears, an independent idler shaft, and roller bearings on the thrust screw. The bottom bevel gear and thrust screw had matching machined flats with a threaded jam nut to hold the bevel gear securely in place. Sib Simes used Binkley dolly parts to build his jacks, which were rated at 29,000 lbs. This gave a yield strength of 10,000 lbs. and a recommended jacking capacity of 9,500 lbs. Sib sold his jacks in the nineties following his illness, Allen Anderson managed the company and later purchased the company. Also at that time Binkley sold out to Holland who used compatable parts, but the parts were not completely identical.

• Sib Simes jacks have been refurbished and sold with a full warranty.
