PROBLEM TO BE SOLVED: To provide a movable beam lift possible of drive with small power, lighter in weight and inexpensive manufacturing cost for a walking beam type carrier device in a heating furnace. SOLUTION: A movable beam lift 4 for a walking beam type carrier device lifts a movable beam 2 while latching at least two levers to a connecting rod 16 reciprocating in a walking beam carrier device 1 for a heating furnace. Each of the levers formed into a hooked lever 9 has a bent portion pivotally mounted on bearings 13a, 13b fixed to a foundation concrete and the end pivotally mounted on the side of the connecting rod 16 on the lower part of a T-shaped bearing 6, the T-shaped bearing 6 being pivotally mounted at its upper part on two lift rollers 5a, 5b, the lift rollers 5a, 5b being put in contact with respective shift rails 3 fixed to the lower face of the movable beam 2.
