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.

Informasi Keselamatan
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.
- Jauhkan tangan dan kaki dari bagian yang bergerak selama pengoperasian.
- Periksa dongkrak untuk mengetahui adanya kerusakan atau keausan sebelum setiap penggunaan. Jangan gunakan jika rusak.
- Wear appropriate personal protective equipment (PPE), such as safety gloves and eye protection.
Pengaturan
- Membongkar: Carefully remove the SJ156 screw jack from its packaging. Inspect for any visible shipping damage.
- Penempatan: 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.
