New Cat Hammers Retain Popular Features
Caterpillar has added three models to
the E Series Hammer line—H140Es,
H160Es and H180Es—for use on medium
and large excavators ranging from its 324E
to the 374D L. The energy classes of the
H140Es, H160Es and H18Es are 6,000 ft-lb (8,135 J), 8,500 ft-lb (11,525 J) and
12,000 ft-lb (16,270 J), respectively. The
E Series Hammers build on the proven D
Series Hammers, which the new hammers
replace. E Series Hammers feature a new
symmetrical housing design, which allows
rotating the housing 180° to compensate
for wear. The lower portion incorporates
rock edges that add protection to the hous-ing and enable quick positioning of boul-ders. An optional wear package is available
to improve hammer durability in severe
applications. Features carried over from the
D Series include automatic shut-off, which
instantly stops the hammer when the tool
breaks through material. The system
increases hammer reliability and durability
by eliminating high internal stresses creat-ed by blank firing. Another feature contin-ued in each E Series Hammer is the exter-nal pressure control valve, which reduces
service time when an adjustment is neces-sary. The E Series Hammers are designed to
be field serviceable with common hand
tools. Sound suppression is standard for
environmental protection and operator
comfort. The new hammers’ settings are preprogrammed in Cat excavator tool con-trol systems for easy set up. Oil flow and
pressure are fully adjustable in the tool con-trol program, and actual hammer working
hours can be recorded for routine mainte-nance purposes.
