HD-973P Series Multi-Level Parking Lift 25 P/N 5900076 — Rev. B3 — January 2024
Safeties cannot engage. However, if a Cable were to break (which very rarely happens), the Slack
Safety for the broken Cable immediately engages, preventing the Runways from falling.
Installing the Ladders and Top Cap
Each Post has two Ladders, each gets installed on the inside back of a Post; Ladders are secured at
the top and the bottom. Note that these Ladders are not interchangeable and must go in the correct
slots. The four Ladders with 31 holes go in the outer slots of the Post, and the other four Ladders with
13 holes go to the inner slots. The Top Caps secure the Ladder at the top of each Post and hold the
ends of the Cables.
Note: It is much easier to secure the bottom of the Ladders once the Crosstubes have been
raised, so that portion of installing the Ladders is described in Securing the Ladders.
⚠ WARNING Make sure to install the Ladders correctly. If they are not installed correctly, the
Safety Locks on your Lift may not hold the weight of a Vehicle, putting anyone
under the Platform in danger.
Slots are created by the Slide Blocks on the Crosstube Gusset. Front and Side views combined. Not
to scale. Not all components are shown.
