Interactive Garage Crane

Objective: Hook the box and move it to the right side!

Avoid obstacles with the hooked box

Controls

How to play: Use the left/right arrows to move the bridge. Use Hook Up/Down to raise and lower the hook. Hook the red box (look for the white dot) from the left side and transport it to the right side. Avoid hitting obstacles with your payload - the crane can pass through, but not the hooked box! Reset (↺) restarts the level.

Crane Specifications

Based on the Reddit post by u/67triumphGT6.

Lifting Capacity: 1 ton hoist (CM Lodestar), mounted to a top-running trolley.
Dimensions: Span: 44' (across the shop)
Length: 60' (down the shop)
Clearance: Max hook height is just under 13' with 14' ceilings.
Main Girders (Bridge): W14x34 I-beams.
Runway Beams (Rails): W6x20 I-beams.
Support Posts: 5" x 5" x 3/16" square steel tubing.
Bridge Drive System: Motorized via a 1hp 3-phase motor with a 10:1 gearbox, turning a 44' drive shaft.
Hoist Trolley Drive: Non-powered (manual push/pull along the bridge).
Power & Control: The 3-phase motor is powered by a VFD (Variable Frequency Drive) that converts 120V 1-phase AC to 240V 3-phase AC. This allows for adjustable acceleration, deceleration, and speed.
Wireless Operation: The original wired pendant for the hoist and bridge was reverse-engineered. An Arduino microcontroller and Solid-State Relays (SSRs) were used to create a custom wireless remote control system.

Owner's Note on Engineering: "The trade off with a top runner is that torsional load buckling becomes a concern, but 1 ton is far below the threshold. Hard to see in the pics, but there's a horizontal truss tying the beams together to increase LTB [Lateral Torsional Buckling] resistance."
