The little surprise in this marble run happens on the way up. Turn the handle and an alternating wooden staircase passes a marble between its steps before releasing it onto the tracks. The UGEARS Stepped Hoist turns the finished build into something you can keep setting in motion.
Choose the movement you want to watch
The three-stage lift distinguishes model 70157 from the Chain Hoist. Its routes include a funnel and other obstacles, while an auxiliary seesaw returns marbles through the system. The maker includes ten marbles with the 355-part kit. Looking closely at the lift photographs is more useful than choosing only by the box artwork.
This is hand-powered. You supply the steady crank movement; it does not become an unattended desktop machine after assembly. That can be part of the enjoyment: one hand sets the pace while you follow a particular marble. If you want continuous powered motion, this kit is not supplied that way.
Leave room for building and adjusting
The assembled run occupies roughly 29.5 by 27.5 by 27cm. A stable surface and access around the sides matter more than a narrow display ledge. The maker rates it Advanced, ages 14+, so small components and the finished moving mechanism are not suitable as a preschool marble toy.
Expect careful fitting, preparation and checking as instructed. Test sections progressively instead of waiting until the whole structure is finished to discover a sticky movement. This is a hobby project, not evidence that every kit will run perfectly without adjustment.
Start with one complete circuit
Compatible UGEARS runs can connect using the modular system, but extra runs are separate purchases. One Stepped Hoist already offers a complete activity. Choose it if you enjoy building and tracing a visibly different lift; choose a simpler snap-together track if quick, flexible construction matters more than intricate wooden mechanics.
