Replaces 57500.\u003c\/p\u003e\n\u003cp data-start=\"484\" data-end=\"954\"\u003eThis specialized interlock assembly is used on Porch-Lift vertical platform lifts where a mechanical cam system controls landing gate unlocking. Often referred to as a \u003cstrong\u003es\u003c\/strong\u003e\u003cstrong data-start=\"652\" data-end=\"695\"\u003etar wheel or daisy wheel lock\u003c\/strong\u003e, the mechanism uses a rotating cam profile that engages the lift’s vane as the platform reaches the landing. This interaction allows the gate to unlock only when the platform is properly positioned, maintaining the safety circuit required for lift operation.\u003c\/p\u003e\n\u003cp data-start=\"956\" data-end=\"1417\"\u003eThe assembly is commonly found on Porch-Lift accessibility lifts originally manufactured by American Stair-Glide and later produced under the ThyssenKrupp Access brand. Its integrated design combines the cam actuator, electrical switching components, and mounting structure into a single compact unit that installs at the landing gate location. This configuration ensures reliable gate locking while coordinating electrical signaling to the lift control system.\u003c\/p\u003e\n\u003cp data-start=\"1419\" data-end=\"1683\"\u003eBecause of its distinctive star-shaped cam design, this interlock is easily recognizable compared to more conventional linear or roller-style gate locks. It serves as a direct replacement for legacy Porch-Lift installations that utilize the daisy wheel cam system.\u003c\/p\u003e\n\u003cp data-start=\"1685\" data-end=\"1703\"\u003e\u003cstrong data-start=\"1685\" data-end=\"1703\"\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1707\" data-end=\"1768\"\u003eInterlock assembly type: Star wheel \/ daisy wheel cam style\u003c\/li\u003e\n\u003cli data-start=\"1771\" data-end=\"1844\"\u003eApplication: Vertical platform lift (VPL) landing gate safety interlock\u003c\/li\u003e\n\u003cli data-start=\"1847\" data-end=\"1894\"\u003eCompatibility: Porch-Lift accessibility lifts\u003c\/li\u003e\n\u003cli data-start=\"1897\" data-end=\"1984\"\u003eLegacy manufacturer compatibility: American Stair-Glide and ThyssenKrupp Access units\u003c\/li\u003e\n\u003cli data-start=\"1987\" data-end=\"2048\"\u003eActuation method: Rotating cam engages lift vane at landing\u003c\/li\u003e\n\u003cli data-start=\"2051\" data-end=\"2143\"\u003eIntegrated components: Mechanical cam assembly, electrical switch contacts, wiring harness\u003c\/li\u003e\n\u003cli data-start=\"2146\" data-end=\"2225\"\u003eMounting configuration: Pre-assembled interlock housing for gate installation\u003c\/li\u003e\n\u003cli data-start=\"2228\" data-end=\"2291\"\u003eElectrical connection: Multi-wire harness with plug connector\u003c\/li\u003e\n\u003cli data-start=\"2294\" data-end=\"2376\"\u003eConstruction: Metal housing with precision cam and internal switching components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2378\" data-end=\"2665\"\u003eProperly functioning gate interlocks are critical components in accessibility lift systems.
