A loader which can provide the operator with enhanced safety comprises a vehicle body carrying a canopy and a rotating vehicle axle, a seat bar mounted to the canopy for swinging movement between a raised position and a lowered, operator restraint position, a parking lever shiftable between a brake position and a release position and cooperatingly associated with the seat bar, an axle lock operatively connected to the seat bar and the parking lever and operable to lock or release the vehicle axle, and conditional force delivery mechanism for normally allowing the axle lock to brake the vehicle axle and for causing the axle lock to release the vehicle axle only when the seat bar is in the lowered position with the parking lever shifted into the release position.

Loader with an improved parking brake device

A loader includes a vehicle body with a canopy and a seat, a hydraulically operated working implement and a hydraulic control valve unit for controlling flow of working fluid to and from the working implement. Mounted to the canopy of the vehicle body is a seat bar for swinging movement between a lowered position in which an operator is secured to the seat and a raised position in which the operator is released from the seat. A pedal with a dog plate is operatively associated with the control valve unit and tiltable about a horizontal axis between an operative position wherein the control valve unit allows the fluid to be fed to the working implement and a neutral position wherein the control valve unit inhibits delivery of the fluid to the working implement. A detent lever is adapted to swing about a vertical axis between a locking position wherein the detent lever engages with the dog plate to keep the pedal in the neutral position and an unlocking position wherein the detent lever disengages from the dog plate to permit the tilting movement of the pedal. The detent lever can be moved into the locking or unlocking position by means of a lever actuator.
