High-Strength Components:
Critical load-bearing parts—such as the gears and racks—are manufactured using 42CrMo alloy steel treated via a quenching process. Compared to standard carbon steel, this material offers superior strength; it resists deformation and tooth chipping under heavy loads, ensuring a significantly longer service life.
Dual-Pawl Self-Locking Mechanism:
This mechanism comes with a dual-pawl structure; the upper pawl locks to prevent slippage during lifting, and the lower pawl stops sudden falls when lowering, allowing the load to stop at any desired position and effectively eliminating accidental drop risks.
Mechanical Structure:
Featuring a fully mechanical design, this product does not require hydraulic fluid like hydraulic jacks, thus removing all oil leakage hazards; it remains stable and reliable in both high and low temperature working environments.
Side-mounted carrying handles facilitate easy handling and relocation, which makes the unit ideal for work environments—such as construction sites and workshops—where frequent repositioning is required.
The handle features a retractable design; once operations are complete, it can be retracted to minimize the unit's footprint, thereby simplifying storage and transport.
A claw hook is mounted on the lower side of the base, enabling the product to effortlessly handle lifting tasks even in extremely low-clearance situations.
