ton pumps that drive hydraulic wheel
motors through a bow-tie chain drive
system. Bosch Rexroth wheel motors
are used in the midrange models and
the larger frame machines incorporate Poclain drive motors. The drive
system can be configured as a two-speed option, using the same drive
motor make in a different assembly.
Maximum travel speed is 12 mph.
Axle pods are equipped front and
rear and sealed to protect against
dust, sand and debris. These seals are
designed to extend the life of the axle
bearings, Terex said, reducing maintenance. Four tire options are available
— standard, heavy-duty, extreme and
solid rubber for scrap work.
Terex said it designed the SSLs
with a lower profile for greater stability.
The machines have 10. 5 in. of ground
clearance and 29° rear angle of departure on the medium-frame loaders (the
TSR50, TSR60, TSV50 and TSV60)
and 26° on the large-frame loaders (the
TSR70, TSR80, TSV70 and TSV80).
These features, Terex said, improve
the machine’s ability to traverse soft,
uneven terrain for greater productivity.
Tractive effort is rated 8453 lb. on the
medium-frame models and 8700 lb. on
the large-frame units.
A Cassapa gear pump powers the
loader circuit. The SSLs are designed
with load-sensing hydraulics to ensure
that fuel and energy are not wasted on
surplus hydraulic power. Gate hoses
are used to connect the hydraulic
A range of attachments is available for use with the SSLs including augers, backhoes, rotary brooms,
general-purpose buckets, light material buckets, multipurpose buckets,
dozer blades, pallet forks, power box
rakes, snow blades, snow blowers,
stump grinders, trenchers, vibratory
rollers and the Loegering Eliminator
rakes. Each attachment comes standard with the necessary hydraulic
lines and connectors or electric connections. Rated operating capacity
for the machines ranges from 1500 to
3000 lb., depending on model.
The hydraulic circuit is also electro-
over-hydraulic and controlled by
Bosch Rexroth ISO joysticks in the
cab. The cab is outfitted with analog
gauges for engine speed, fuel level
and engine temperature. The joystick
controls feature built-in switches for
auxiliary hydraulics and electric control
of attachments, while each model is
pre-wired for quick, easy connection
“Everything from the hydraulics to
the balanced machine weight ensures smooth operation, reduced
vibrations and exceptional stability,
contributing to improved operator
comfort,” said Wright. dp
