Short Straight Line Skates utilize many of the same features of their longer counterpart in a shorter frame. These rugged machinery moving dollies are fabricated from high quality North American steel and fully welded to handle the weight of your heaviest and densest loads. Two rows of tandem rollers in a long frame provide maximum stability under load. These Skates are favored for handling the heaviest jobs for machinery movers, riggers, stevedores and contractors. Capacities range from 6 Tons (12,000 lbs.) to 30 Tons (60,000 lbs.).
