Trucks
and Carts - Most conventional trucks can be readily adapted to Trukveyor
operation through simple selectivity devices. Even the common hand truck,
found in most industrial plants, is easily converted for use in Trukveyor
systems. Custom made trucks can also be furnished to meet special needs.
For towline systems a plain tow pin is either manually or automatically
dropped into the chain slot.
Roll-tow
chains - Forged steel riveted chain maximizes strength while minimizing
weight. It can be easily assembled and disassembled without tools. All
parts are heat treated for enhanced strength and maximum wear resistance.
Threaded extended pins are used to attach pushers and idlers.

Roll-tow
(TA and TR) pushers - TA pushers capture and hold truck tow pins
on monoplane installations. A counterweighted pawl is depressed by the
tow pin as it enters the pusher. Upon engagement, the pawl returns to
its normal position capturing the tow pin. The rear of the pusher is
inclined to allow tow pin

engagement from behind. The frame and pawl are constructed of rugged,
malleable iron castings. TR pushers are used for applications involving
switching. Construction and operation of TR pushers is similar to TA
pushers, except for side exit ramps which are cast into the body, allowing
the pin to be lifted out of the pusher at switch points.
Idlers
- SA idlers are used to support chain between pushers. SA idlers have
a rugged malleable iron frame and two wheels identical to those on
pushers.
Bolt-on
Wheels - Wheel Bearings for all pushers and idlers have precision
balls rolling on hardened, concentrically ground raceways to assure
smooth rolling and long life. Standard wheels are bolt-on type, minimizing
time and cost, when replacement becomes necessary.
Drives
- Constant or variable speed drives are available for speeds up to a
normal maximum of 120 fpm (36mpm), and a wide range of chain pull capacities.
Special drive applications are available upon request. Caterpillar drives
consist of endless precision steel roller chain with hardened drive
dogs. Chain back-up guides ensure proper dog engagement. Caterpillar
chain tension is easily adjusted to ensure long life. Overload protection
is normally provided electrically at the control panel and/or mechanically
by a shear pin sprocket at the drive. Removable cover plates accommodate
cross traffic with wheel loads of up to 5,000 lb (2200 kg). Drive motors
are normally furnished with a "soft start" provision, so that
the system has a smooth ramp up to full speed.
Chain
- Forged steel rivetless chain is identical throughout the system. Strong
and lightweight, it can be easily assembled and disassembled without
tools. All parts are heat treated for high strength and wear resistance.
Wear pads on bottom sidebars extend service life.
Mainline
Pushers - Mainline chain pushers are made of forged steel components
to form a pusher integral with the chain. This pusher face extends
the full chain width to assure positive pin pickup. Projection on
the pusher dog helps ensure positive pin pickup. Pushers have wear
shoes to distribute the load. Chain design permits locating pushers
on multiples of 8" spacing.
Powered
Sliding and Transfer Pushers - These pushers are made from forged
steel and can be substituted for the normal top link at minimum intervals
of 8". Close pusher proximity allows for faster pickups and transfers.
UHMW Turns
- Turns have a UHMW wear bar which is designed to have two wearing surfaces,
both of which can be used prior to replacing the bar. Once the front
active surface has worn, simply remove the bar, rotate it 180 degrees,
and reinstall. Additionally, the turns need no routine maintenance.
Controls
and Electrical Accessories - Control panels contain a motor starter,
fused

disconnect switch (interlocked to the door panel), control circuit transformer,
primary overload relays with external reset button, and an integral
pushbutton operator station. The panels have a space for additional
control relays. A warning horn time delay relay is also provided. Pushbutton
stations are usually included. For normal operation, start-stop stations
are recommended for main conveyor operation and control points with
stations strategically located along the conveyor path. Stations are
latched so that the conveyor is not restarted until the station which
was stopped has been restored to its running position. The conveyor
controller can be interlocked with a PLC or computer to keep supervisory
computer systems advised of system operation.
