The model with the levers on the rear ?
Yes it can be fixed - but you must take it apart.
The lift is a toothed-contraption which will not lift a brick. If it has torn cogs... you're outta luck.
What sort of noise does is make ?
The forks swing in weak-plastic hinges. Same story as with the brick.
The handle still moves OK? Commonly broken. Hope nothing is missing.
I have repaired many small plastic parts with a 25-watt wood-burner-iron.
( or, your empty glue gun will also melt the plastic)
Basically, you are spot-welding the plastic together.
The strongest glue is JB-Weld at any auto-parts store.
Don't blame the brick. Grandson used the poodle !
