Electrically operated working vehicle

A dump truck is provided with a ground fault detection device that detects a ground fault detection voltage V0 as a difference between a detection voltage Vp between a positive electrode line of a DC bus and a neutral point N and a detection voltage Vn between the neutral point N and a negative electrode line of the DC bus and detects a ground fault based upon the ground fault detection voltage V0. The ground fault detection device includes a DC component determining section that extracts a DC component V.sub.Ldc from the ground fault detection voltage V0 and determines a ground fault based upon the DC component V.sub.Ldc, and a drive frequency component determining sections (that extract drive frequency components V.sub.LiR, V.sub.LiL of the inverters from the ground fault detection voltage V0 and determine a ground fault based upon the drive frequency components V.sub.LiR, V.sub.LiL.

ROCKER SUPPORT ASSEMBLY

A support rocker configured to be pivotally coupled to a rocker attachment interface of a space frame comprises a rocker body having a pivot bore configured to receive therethrough a pivot pin to pivotally couple the rocker body to the rocker attachment interface; and a rocker support insert provided on a top portion of the rocker body. The rocker support insert can be removably coupled to the top portion of the rocker body, and the rocker support insert can define an upward-facing contact surface.
