The hand truck/forklift as disclosed in this application is new and useful as an improvement of the conventional hand truck in that it enables lifting of loads up to four feet high as-well-as transporting loads commonly carried on a conventional hand truck. This lever operated lift is also an improvement in that it enables lifting of heavy loads by a person without the use of more expensive power operated lifts where space and environmental concerns make them impractical to operate. This lever operated lift enables the operator to lift heavy loads safely equaling the lifters body weight plus his lift strength while keeping his back in an up-right posture. The lever lift assembly is also new and useful in that it allows the operator to lift a load and allows that load to be held at a selected height by use of a sleeved punched post frame assembly with spring loaded set pins which are manually retracted by use of hand operated cable from the lever side of the lift. The power operated lift as disclosed in this application is new and useful as an improvement in a forklift assembly in-that-it provides a means of extending the reach of a lift mass by means of a boxed rotary frame attached at fixed points on a fixed or extendable lift mass assembly by use of chains with cogwheels and hydraulic jack assemblies as illustrated in attached drawings. This invention in either form can also be used as a supplement to conventional hand trucks and forklifts by transporting and lifting loads onto and from hand trucks to work counters, trucks etc. and loading pallets for heavier conventional lifts for improved efficiency in material handling.
