A hoisting apparatus includes at least one pair of substantially vertical columns defining a frame. A tie bar and a carriage are selectively securable to the at least one pair of columns and oriented substantially perpendicular to the columns. A lifting device connected to the tie bar at a first end and to the carriage at a second end. The lifting device is operable to cause movement of the tie bar relative to the at least one pair of columns when the carriage is secured to the at least one pair of columns and to cause movement of the carriage relative to the at least one pair of columns when the tie bar is secured to the at least one pair of columns. The hoisting apparatus is connectable to a counterweight of a belt conveyor for raising or lowering the conveyor in a series of incremental hoisting steps.
