Hand truck

A hand truck
"Pry Lever Bar" used on docks, in warehouses & around railroad stations during steam locomotive era

A hand truck, also known as a two wheeler, stack truck, trolley, trolley truck, sack barrow, sack truck, dolly, or bag barrow, is an L-shaped box-moving handcart with handles at one end, wheels at the base, with a small ledge to set objects on, flat against the floor when the hand-truck is upright. The objects to be moved are tilted forward, the ledge is inserted underneath them, and the objects allowed to tilt back and rest on the ledge. Then the truck and object are tilted backward until the weight is balanced over the large wheels, making otherwise bulky and heavy objects easier to move. It is a first-class lever.

Some hand trucks are equipped with stairclimber wheels, which, as the name implies, are designed to go up and down stairs. Stairclimber wheels can sometimes be problematic when trying to turn on flat ground as four wheels in a fixed position will be in contact with the ground.

Hand trucks are fabricated from many different types of materials, tube steel, aluminum tube, aluminum extrusion and high impact plastics. Most commercial hand trucks that are used for beverage and food service deliveries are rugged and very light weight. They are usually designed from two extruded aluminum channel side rails and cast aluminum or magnesium parts.

Some of the options that may be considered are the types of wheels, stair climber, handle type and size of wheels.

Other things to be considered should be the load shape compared with the back rest shape, so i.e. cylindrical loads should sit on curved back rests. Also the environmental condition that the hand truck will operate in. For example on loose or uneven ground oversize wheels are a great advantage, solid or puncture proof foam tires where punctures could have an effect.

Bear in mind the size of the load in comparison to the length of the toe plate or nose plate, a good rule of thumb is that the toe or nose should be 1/3rd of the length of the load.

Hand trucks are sometimes used as baggage carts by porters in train stations and skycaps at airports.
