The Simplex SJ156 Mechanical Screw Jack is a robust and reliable tool designed for various heavy-duty applications. Its sturdy and simple design makes it suitable for supporting machinery, construction tasks, structural moving, and general maintenance. Key features include a four-way head assembly for precise leveling and a serrated steel cap that floats 9 degrees on a chrome-moly ball, reducing friction and assisting in centering the load. This jack is engineered to support loads without creep-down and incorporates a welded stop to prevent accidental over-extension of the screw.

ข้อมูลด้านความปลอดภัย
Always prioritize safety when operating the Simplex SJ156 Screw Jack. Failure to follow safety guidelines can result in serious injury or property damage.
- Ensure the jack is placed on a stable, level, and firm surface capable of supporting the load.
- Never exceed the jack's rated load capacity of 12 tons (24,000 pounds).
- Always center the load on the jack's cap to prevent slippage.
- Use appropriate cribbing or safety stands to support the load once it is lifted. Do not rely solely on the jack for prolonged support.
- ให้มือและเท้าอยู่ห่างจากชิ้นส่วนที่กำลังเคลื่อนไหวในระหว่างการทำงาน
- ตรวจสอบแม่แรงว่ามีรอยชำรุดหรือสึกหรอหรือไม่ก่อนใช้งานทุกครั้ง ห้ามใช้หากพบว่าชำรุด
- Wear appropriate personal protective equipment (PPE), such as safety gloves and eye protection.
การตั้งค่า
- การแกะกล่อง: Carefully remove the SJ156 screw jack from its packaging. Inspect for any visible shipping damage.
- การจัดวาง: Position the jack on a flat, stable, and solid surface directly beneath the object to be lifted or supported. Ensure the ground can withstand the concentrated load.
- Load Centering: Place the object's lifting point directly onto the center of the jack's serrated steel cap. The floating cap is designed to assist in centering the load.
- Lever Bar Insertion: Insert a suitable lever bar (not included) into one of the four holes in the jack's head assembly. Choose the position that provides the best leverage and clearance for your application.
คำแนะนำการใช้งาน
Follow these steps for safe and effective operation of your Simplex SJ156 Screw Jack:
- การยกของหนัก: With the lever bar inserted, rotate the head assembly clockwise to raise the screw and lift the load. Apply steady, controlled force.
- การลดโหลด: To lower the load, rotate the head assembly counter-clockwise. Lower the load slowly and in a controlled manner.
- รองรับการโหลด: For prolonged support, always use additional safety stands or cribbing once the desired height is achieved. The jack is designed to hold the load without creep-down, but secondary support is crucial for safety.
- Over-extension Prevention: The jack includes a welded stop to prevent accidental over-extension of the screw. Do not attempt to force the screw beyond this stop.
