ZJJ-1015, 10 Ton 6" Stroke Journal Mechanical Jack
The Zinko ZJJ-1015 journal jack delivers heavy-duty lifting precision tailored for railway maintenance, bridge construction, shipbuilding, and heavy machinery installation.
Designed to optimize high-capacity industrial servicing, this 10-ton mechanical jack utilizes a 100% fluid-free gear system that completely eliminates the risk of seal blowouts, oil leaks, or performance loss in extreme environmental temperatures. It features a compact 4.25" base layout supporting a 2.56" diameter saddle, providing stable placement for a 5.90" lift stroke within a tight 11.02" to 16.92" clearance. Manufactured and assembled in Japan under strict quality standards, the assembly guarantees exceptional metallurgy and tighter structural tolerances for professional-grade reliability.
The internal drive relies on a precision-forged pinion and a beveled ring gear engineered with a profile-shifted tooth form to guarantee continuous interlocking and smooth, slip-free power transfer under maximum load. For absolute operator safety, the jack incorporates self-locking buttress threads that physically block the ram from creeping or dropping, ensuring the load remains rigidly locked at height until the operator manually drives the low-effort ratchet handle. This unit can be paired with the ZJTB-1530 horizontal traversing bed for lateral shifting or specialized safety beds for enhanced base stability, sold separately.
Special Features:
- Unique construction bearing is made for longer life and smooth horizontal advance.
- Rigidly designed screw made by chrome -molybdenum steel to withstand excessive load.
- Beveled ring gear interlocks with the precision forged pinion to provide shifted tooth form for strong and excellent interlocking.
- Special ratchet handle interior design with nickel-chrome wheel and plunger enables strong rotation for an easy , smooth operation.
- Buttress threads will not creep down under load.
- Operable vertically or laterally (lateral movement requires optional traversing bed).
