Claims

[Scope of utility model registration request]

(1) A work vehicle such as a dozer or loader, a lift arm whose base end is pivoted to the vehicle body and whose tip end is equipped with a working device such as a blade or packet, and a shift cylinder that drives the lift arm up and down. A safety link mechanism for lifting a work machine, comprising: a non-use position along the lift arm with the base end pivotally supported on the lift arm; and a use position spanning the cylinder tube of the lift cylinder or the vehicle body side. A link for selectively and detachably connecting the free end side of the safety link and the corresponding link to the lift arm and either the cylinder tube or the vehicle body side. A safety link mechanism for lifting a work machine, comprising a connecting means.

(2) The link connecting means includes a movable side bracket that is integrally formed with the lift arm and connects the free end side of the safety link in a non-use position, and a movable side bracket that is fixedly installed on the cylinder tube of the lift cylinder or the vehicle body and that connects the free end side of the safety link in a non-use position. A fixed side bracket for connecting the free end side of the link in the use position, and a link connecting pin for selectively engaging and disengaging the free end side of the safety link to either one of these movable side or fixed side brackets. A safety link mechanism for lifting a working machine according to claim 1 of the utility model registration claim, characterized in that:

(3) Registration of a utility model characterized in that the link connecting pin is maintained in a prevented state by a lock pin inserted when the safety link is connected to the bracket and a locking pin inserted into the lock pin. A safety link mechanism for lifting a work machine according to claim 2.

(4) Practical use characterized in that a rear protector for protecting the rear part of the vehicle body is integrally formed, a rear hook is integrally formed on the rear protector, and a front hook is integrally formed on the working device. A safety link mechanism for lifting a working machine as set forth in claim 1 of the patent registration claim.
