LS 25 ZIL-131 AL-30 (Model PM-506 / PM-506D) V1.0.0.0
The ZIL-131 AL-30 (Model PM-506 / PM-506D) is a quintessential Soviet hydraulic fire ladder truck. Built on the legendary ZIL-131 6×6 military-grade all-terrain chassis, this configuration was widely deployed by fire brigades across the USSR and Warsaw Pact countries for high-rise rescue and firefighting operations.
Key Specifications & Performance
Chassis: ZIL-131 / ZIL-131N (6×6 wheel drive for excellent off-road and rough-terrain mobility).
Superstructure Type: AL-30 (Avtoteleskopeshka 30), featuring a hydraulic-drive telescopic ladder system manufactured historically via specialized plants like the Torжок factory (TMZ).
Maximum Lifting Height: ~30 to 32.2 meters (roughly 98–105 ft), making it suitable for multi-story residential and industrial buildings.
Working Load / Capacity: Designed to support firefighters and rescue loads on the ladder sections (typically rated for structural loads/rescue baskets starting around 120–160 kg+ depending on the specific sub-variant and extension angle).
Outreach: Maximum horizontal reach of up to roughly 16 meters under optimal configurations.
Engine: ZIL-508 / ZIL-130 6.0L V8 gasoline engine producing around 150 horsepower, coupled with a manual transmission and a two-stage transfer case.
Crew / Combat Team: Usually accommodated a crew of 3 personnel in the cabin.
Total Gross Weight: Approximately 10.2 to 10.4 tonnes.
Operational Role
Unlike standard urban fire engines that primarily transported water and pumps, the PM-506/PM-506D series focused heavily on vertical reach, evacuation, and delivering fire hoses or rescue personnel directly to upper floors. Outriggers (stabilization jacks) were deployed from the sides of the chassis to ensure a safe, rigid foundation before elevating the heavy hydraulic ladder booms.
