The Cat® Skid Steer Loader (SSL) and Multi Terrain Loader
(MTL) have earned the distinction of being tough, reliable
machines that perform a variety of tasks competently, while
providing exceptional convenience and control. Now, the new
B-Series 3 loaders — SSL models 216B3, 226B3, 236B3, 242B3,
252B3 and MTL models 247B3 and 257B3 — incorporate design
refinements that make them even more capable, more reliable,
safer and easier to operate. In addition, a larger engine and more
powerful hydraulics for the 242B3 and 257B3 make these models
‘power-dense’ machines that maintain a nimble size and excellent
maneuverability.
Specific design refinements for all B-Series 3 models
include a redesigned ‘dead-engine lower valve’, single
electronic control module (ECM), which is relocated for
improved access and reliability, plus new ECM-enabled
features. A heavy-duty battery (880 CCA) is now
standard equipment on larger models, and a headliner is
added to the optional ‘Comfort Package’.
The redesigned dead-engine lower valve further
promotes safe operation by providing an easier-to-use,
more-positive means of lowering the lift arms —
allowing safe exit for the operator — if the machine
should run out of fuel or the engine stall with the lift
arms raised. The long cable and pull-type knob used to
activate this system on B-Series 2 models has been
replaced in B-Series 3 models with a low-effort, lowmaintenance
lever-action handle that acts directly on the
hydraulic relief valve.
The new single ECM, relocated to the back of the
cab (from the lower frame on the B-Series 2 models),
provides easier access to fuses, relays and the Cat
Electronic Technician port. The new ECM and its relocation also
simplify wiring and reduce the number of connections.
New features enabled by the ECM include automatic glowplug
activation, expanded diagnostic capability and use of an
optional on-demand cooling fan that spins the fan only as fast as
required by the machine. The optional fan improves fuelefficiency,
reduces sound levels and provides faster warm-up. For
the model 226B3, the new ECM also allows automatic activation
of the optional high-flow auxiliary-hydraulic system when a highflow
work tool is connected.
