Rocker Jack eases tandem axle trailer operations

Valley's new Rocker Jack is designed as a safe device for changing tires on tandem axle trailers. The jack's rocker shape allows operators to simply drive their trailer onto the jack to elevate the corresponding tire, according to the company.
 
The jack also features all-steel construction and a ribbed surface for maximum tire grip, and can be used in both tire positions. It is rated for a total load capacity of 20,000 pounds, can be stored inside a vehicle or on a trailer and can flipped over to function as a wheel chock.
