The present invention relates to a load lifting unit for a lift truck, and more particularly, a load lifting unit for a counterbalance type lift truck. In the invention, to increase the loading capacity and longitudinal stability of the lift truck as well as to improve the forward view from the lift truck, two lift cylinders (7) are separately disposed on the sides of a pair of upright assemblies (1) of the load lifting unit, respectively, to provide a space (17) between the upright assemblies (1) for allowing a lift member (4) to be lifted and lowered within the space and for allowing actuating means (32) (55) (82) (90) (120) and (127) of attachments (26) (57) (76) (92) (H) and (A) for various operations, which attachments are engaged with the lift member (4) to be accommodated within the space. The load lifting unit is used for the operation of transferring cargo.
