摘要
The invention relates to a full free-lift triplex forklift mast assembly withincreased operator forward view, includingan outer mast (1), a middle mast (11), an inner mast (16) and a carriage (30),comprising a pair of lift cylinders (8), located rearwardlyof the outer mast (1), mounted on top of lower cross-tie (31), which uponcommands from the operator extend or retract, thus move themiddle mast (11) accordingly in vertical direction, without said liftcylinders (8) obstructing the space between the inner mast profiles(29), a pair of lift chains (3), driving the inner mast (16) in verticaldirection, with each connected to an outer mast chain anchor (5) onone end, and to a multifunctional lift base (22) on the other end, disposedover laterally symmetrically positioned lift chain pulleys (13),which are mounted to the middle mast upper cross-tie (32) rearwardly of themiddle mast (11), without said lift chains (3) obstructingthe space between the inner mast profiles (29), a pair of free-lift cylinders(21), located rearwardly of the inner mast (16), mountedon top of each multifunctional lift base (22), which upon commands from theoperator extend or retract, thus move the free-lift chainpulleys (20) accordingly in vertical direction, without said free-liftcylinders (21) obstructing the space between the inner mast profiles(29), a pair of free-lift chains (18), driving the carriage (30) in verticaldirection, with each one connected to an inner mast chain anchor(19) on one end, and to a carriage anchor (25) on the other end, disposed overlaterally symmetrically positioned free-lift chain pulleys(20) which are mounted on top of the free-lift cylinders (21), with said free-lift chains (18) providing maximized forward visibilitythrough the mast assembly.
