MEMORANDUM FOR: ALL REGIONAL ADMINISTRATORS
THRU: JOHN MILES
FROM: PATRICK R. TYSON
FEDERAL COMPLIANCE AND STATE PROGRAMS
SUBJECT: The "Power Shift" Model Caterpillar Track
Tractors Operating on Inclines in Excess of
30 Degrees Above the Horizontal Plane may
During a recent fatality investigation it was determined during the course
of the inspection that the "power shift" model caterpillar track tractors
when operating on inclines in excess of 30 degrees above the horizontal plane
may become hazardous. Caterpillar Tractor Company representatives were
contacted by the Directorate of Federal Compliance and State Programs and the
possible hazardous condition was substantiated.
Thereafter, Caterpillar issued a bulletin to all dealers (see attachment),
reminding them of and reemphasizing caterpillars recommendations regarding
steep slope operation. In addition, their operators guides and maintenance
guides will be revised to include more detailed technical descriptions that
will emphasize the need for increased oil level and the amount to be added.
Compliance officers should be aware of this situation during inspections. If
caterpillar equipment is observed during an inspection at a job site,
employers and employees should be alerted to caterpillar's recommendations
for "power shift" track tractors used for steep slope operations.
