KOMATSU PC45MR-5 MINI EXCAVATOR — INCREASED FUEL EFFICIENCY & ENVIRONMENTAL PERFORMANCE
The PC45MR-5 hydraulic excavator is
an hydraulic excavator with tight tail swing radius and swing
boom that hug the machine to help with work in tight spaces.
PC45MR-5 uses up to five percent less fuel than its MR-3
predecessors, with no loss of performance or productivity.The
short-tail PC45/55MR-5 delivers optimal power and digging
speed, even in confined spaces where traditional machines
can’t work: yards, road works, demolition sites, sewers, etc.
Sturdy and very stable, it guarantees maximum safety and
offers complete operator confidence in any working
conditions.
Despite its compact size, the PC45/55MR-5 offers
unequalled comfort. The spacious cab was developed with
exceptional care to details, and the work environment is quiet
and comfortable. Special attention is given to the operator:
ergonomic and dedicated PPC controls, and, in option, an
efficient air conditioning and ventilation system to guarantee
optimal thermal comfort. A much larger cab door makes cab
access a lot easier
POWERFUL AND ENVIRONMENTALLY FRIENDLY • Low
