Safely store and transport a pair of fuel and oxidizer cylinders, common in welding applications, up to 13 in and 10 in Dia, respectively. Constructed using 1-1/4 in Dia round steel tube with continuous welding, these durable, double-cylinder trucks provide optimum safety, strength and longevity. Floor plate made of thick 11 ga steel with safety fins prevents warping or breaking. The zero-lift height loading allows floor plate to lay flat, thereby eliminating the need to lift cylinder during loading and unloading. Caster carriage features heavy steel bars and nylon washers for smooth folding action and easy storage in tight spaces. Corrosion-resistant powder-coat finish throughout for long life and smooth handling. Two heavy duty 1-1/2 x 54 in polypropylene support straps, lab tested to 1138 lb, feature steel cinch buckles for secure attachment of cylinder eliminate any cylinder rolling potential seen in chain-secured units. Included welded loop chains provide a secondary means for securing the cylinders. Exclusive bumper guard edging grips cylinder and minimizes damage to cylinder and hand truck. Triple grip push handle greatly enhances safety on top heavy loads by expanding available grip area for improved leverage and swing radius. Optional locking posts and collar plate system model 35084 ensures total cylinder immobilization or accessorize hand trucks with a tool tray or lockable tool box for securing torches and other equipment models 35388 and 35386 respectively.
