Claims

[Scope of utility model registration request]

A parent-child forklift comprising a parent lift consisting of a forklift main body, and a child lift that is separably attached to the parent lift and has a fork, wherein an object in front is detected at the tip of the fork of the child lift. A first sensor is provided, a stopper for regulating the position of the cargo with respect to the tip of the fork is removably provided on the fork, and a second sensor is provided at the tip of the fork for detecting an object in front of the fork. A sheath fork is detachably provided, the fork and the sheath fork are provided, and a connector is provided for connecting the second sensor to the parent lift side at the same time as the sheath fork is attached to the fork, and either the fork or the sheath fork is provided. On the other hand, a parent-child forklift is provided with an automatic circuit switching means for switching from the first sensor to the second sensor at the same time when the sheath fork is attached to the fork.
