It operates on a mechanical screw-and-ratchet principle, requiring no hydraulic fluid or external power source. The SJ1512 delivers a 9.75-inch piston stroke, making it suitable for tasks that require extended vertical reach. With a plunger diameter of 2.875 inches and a screw diameter of 2.25 inches, this jack is built for stability under load. At 16 pounds, it is portable enough for field use while remaining robust enough for shop and industrial environments. Licensed tradespeople and maintenance professionals working in HVAC, mechanical, and industrial service settings rely on screw jacks like this for controlled, incremental lifting.\u003c\/p\u003e\n\u003cp\u003eThe SJ1512 is used in applications where precise mechanical lifting or load positioning is required. Common scenarios include equipment alignment, machinery installation, structural support during maintenance, and pipe or component positioning. The manual ratchet mechanism allows controlled advancement without power tools. This jack is appropriate for residential, commercial, and light industrial jobsites where portability and simplicity are priorities. Mechanical contractors, millwrights, pipefitters, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9.75-inch piston stroke for extended vertical reach\u003c\/li\u003e\n  \u003cli\u003eManual screw-and-ratchet operation requires no hydraulic fluid or power source\u003c\/li\u003e\n  \u003cli\u003e2.875-inch plunger diameter provides a stable load-bearing surface\u003c\/li\u003e\n  \u003cli\u003e2.25-inch screw diameter supports load control and structural rigidity\u003c\/li\u003e\n  \u003cli\u003eCompact footprint at 6.25 inches length and 2.88 inches width for confined-space access\u003c\/li\u003e\n  \u003cli\u003ePortable at 16 pounds for field and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a manual screw jack for general-purpose mechanical lifting and positioning tasks.

Always ensure the base is fully seated and the load is centered on the plunger before advancing the screw. Mechanical contractors and maintenance technicians should follow applicable ASME and OSHA guidelines for lifting operations. Never exceed the rated capacity of the jack, and never use a jack as a permanent support without supplemental blocking or stands.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJack Type\u003c\/strong\u003e: Screw Jack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiston Stroke\u003c\/strong\u003e: 9.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ENERPAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SJ1512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ENERPAC","offers":[{"title":"Default Title","offer_id":51558464323890,"sku":"SJ1512","price":469.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d0e2b8a8a028fb3c78e51a045c1a3e2.jpg?v=1786412962","url":"https:\/\/voomisupply.com\/products\/enerpac-sj1512-screw-jack-9-75-inch-stroke-manual","provider":"Voomi Supply","version":"1.0","type":"link"}
