Martins Industries has added the Premium Tire Cart to its line of tire handling equipment. The Premium Tire Cart reduces handling and numbers of trips your tire service techs need to make, and helps avoid work stoppage, workplace accidents and injuries, particularly back injuries. The company says the cart enables users to move up to eight 38 1/2-inch tires. The cart can be adjusted to 45-degree and 90-degree angles to ease movement of the cart and access to the tires.
