A hand truck. A hand truck, also known as a hand trolley, dolly, stack truck, trundler, box cart, sack barrow, cart, sack truck, two wheeler, 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.

Wheels with Asanti 28 in (710 mm) rims on a police Hummer H2 car. The wheel size is the size designation of a wheel given by its diameter, width, and offset. The diameter of the wheel is the diameter of the cylindrical surface on which the tire bead rides. The width is the inside distance between the bead seat faces.
This means: If only the front wheels are steered, the rearmost part of the formula can be left out. The most common example is probably the 4×4 configuration. 6×4*4 is the chassis configuration for a vehicle with six wheels where four wheels are driven, in addition, the two front wheels as well as the rearmost two wheels are steered.
Hand trucks (including carts and dollies), the simplest type of industrial truck, cannot transport or stack pallets, is non-powered, and requires the operator to walk. A pallet jack, which cannot stack a pallet, uses front wheels mounted inside the end of forks that extend to the floor as the pallet is only lifted enough to clear the floor for ...
As a wheel and axle is a type of lever, a system of wheels and axles is like a compound lever. [19] On a powered wheeled vehicle the transmission exerts a force on the axle which has a smaller radius than the wheel. The mechanical advantage is therefore much less than 1.
A wheel can also offer advantages in traversing irregular surfaces if the wheel radius is sufficiently large compared to the irregularities. The wheel alone is not a machine, but when attached to an axle in conjunction with bearing, it forms the wheel and axle, one of the simple machines. A driven wheel is an example of a wheel and axle.
Diagram of turning vehicle. On wheeled vehicles with the common type of front wheel steering (i.e. one, two or even four wheels at the front capable of steering), the vehicle's turning diameter measures the minimum space needed to turn the vehicle around while the steering is set to its maximum displacement from the central 'straight ahead' position - i.e. either extreme left or right.
The engine could also be crank started if necessary by a hand crank that is inserted through a hole in the radiator shell. The Model AA was based on a chassis that was similar in design to the Model A Ford, except it was substantially larger and heavier to accommodate the work this truck was designed for. Model AA Ford has a four-speed manual ...
