Virco's rugged HCT4 is the "4x4" of chair trucks. Its four-wheel design, featuring heavy-duty polyolefin tires and ball bearing shafts, eases the operator's work load. The HCT4 moves and stores most Virco stack chairs, including Classic Series model 9018 plastic stack chairs and 8900 Series upholstered stack chairs with ease. NOTE*: Safe Hand Truck Capacities: Unlike storage carts, which support the weight of the furniture entirely with structural steel, hand trucks rely on the strength of the operator to balance the load. For this reason, there is no single "safe capacity" for hand trucks. Conditions such as the size and strength of the operator, the weight of the furniture being moved, and the presence or absence of thresholds, ramps or slick surfaces can all affect the capacity of hand trucks. We recommend starting with small, easily handled loads and adding one or two pieces of furniture at a time to determine the safe capacity for each set of conditions. It's always better to make a few extra trips than to risk injury to yourself or others by overloading a hand truck. Remember, loaded hand trucks can be dangerous! Use common sense.
