Trolley Conveyor
DistribuTek Leaning Center
The trolley conveyor consists of a series of trolleys supported from or within an
overhead track. They are generally equally spaced in a closed loop path and are
suspended from a chain. All trolley conveyors can be assembled with horizontal and
inclined runs, or with vertical or horizontal turns in complex paths. There are,
however, a few restrictions on the length of the conveyor. These units can be designed to carry a wide range of shapes, sizes, and weights. Overhead trolley conveyors
are used to move products through such operations as cleaning, washing, painting,
drying, and blasting. They can also function as simple transport or storage conveyors. The most common type of trolley conveyors are:
I-Beam Systems consist of an endless chain suspended from wheeled
trolleys that roll on the lower flange of an I-beam track. Loads are suspended from
attachments bolted to the trolley brackets. A variety of load carriers can be used.
Power and Systems are an advanced form of the I-beam conveyor.
These conveyors are used extensively in systems where loads must be directed onto
branch lines, and where loads are halted for work or inspection, or accumulated
for storage. In general, these conveyors are used in applications that do not involve
continuous movement of unit loads at uniform rates or at fixed spacings.
Enclosed Track Systems, with square sections, are the most frequently
used form of the overhead conveyor. There are many variations of this type in use,
usually in relatively low-capacity applications. In general, enclosed-track conveyors
are limited
to maximum speeds of 70fpm. Typical systems contain no more than 20 horizontal turns and vertical curves. Usually, each inclined section in the operation
is balanced by a declined section.
