The 4,000-pound, drawbar-pull, gasoline-powered
warehouse tractor (fig. 6-5) has pneumatic tires. It is a
standard medium-duty tractor for outdoor storage
operations. This tractor is used in outside storage areas
for hauling trailers or for towing aircraft. It also maybe
used for general-purpose towing or pulling at freight
sheds, piers, warehouses, or other areas. It has enough
weight, horsepower, and traction to operate on virtually
all types of running surfaces.
The 7,500-pound, drawbar-pull, gasoline-powered
warehouse tractor has pneumatic tires. It is the standard
heavy-duty tractor for outdoor storage operations. This
capacity tractor is available in two sizes. The first type
is the low profile, industrial type tractor with
conventional pneumatic tires on both drive and steering
wheels. The second type is the high flotation model with
oversized pneumatic tires on the drive wheels.
A warehouse trailer is a load-carrying platform
mounted on caster wheels. Standard trailers are
available in a wide variety of sizes and capacities and
may have solid rubber or pneumatic tires. The
caster-steering type has fixed rear wheels that carry
about two-thirds of the load and caster wheels at the
front for steering. There are two models of caster
steering type trailers. They are the 4,000- and
6,000-pound capacity models, similar to the one
illustrated in figure 6-6. The caster steering type trailer
suites indoor operations better.
The fifth-wheel steering type warehouse trailer has
rear wheels mounted on a rigid axle and front wheels
mounted on a center-pivoted steering axle with a
drawbar attachment. This type of trailer is available with
a capacity of either 6,000 or 20,000 pounds. It is more

suitable for heavy loads or for operations over rough
Hand trucks are particularly useful in places where
other mechanical equipment cannot operate because of
space limitations. Hand trucks may be constructed of
wood or metal. They are often preferable to and more
economical than a piece of mechanical equipment for
the movement of a single item.
The four-wheel platform hand truck (fig. 6-7) is
advantageous for breaking out retail issues for bins or
carrying light loads. Platform hand trucks are
commonly used for any operation involving short hauls
with frequent stops.
The two-wheel hand truck (fig. 6-8) has two
handles, a platform where the load rests, and a pair of
wheels attached to the bottom of the framework. It has
a blade that extends at an angle from the bottom of the
platform to hold the load. It also has two metal legs
located near the top of the platform to help bear the load
when the truck is resting flat on the ground. The platform
of the truck may have flat crossbars for handling boxes
or crates, or curved crossbars for handling barrels or
