A fork assembly lift mechanism (24) is disclosed that is configurable for use in a material handling vehicle (10) for moving a fork assembly (14), including a fork trail assembly (66), between a lowered position and a raised position. The fork assembly lift mechanism comprises a master cylinder (52a,52b) coupled to a truck body (12) and the fork assembly (14) for moving the fork assembly (14) between the lowered position and the raised position, and a slave cylinder (64a,64b) coupled to the fork assembly and the fork trail assembly (66) for moving the fork trail assembly (66) between the retracted position and the extended position. The slave cylinder (64a,64b) is in fluid communication with the master cylinder (52a,52b) such that actuation of the master cylinder results in actuation of the slave cylinder to move the fork assembly (14) between the lowered position and the raised position, and to move the fork trail assembly (24) between the retracted position and the extended position.
