When comparing prices, you must verify the Rated Lifting Capacity (typically 0.8t, 1.6t, 3.2t, or 5.4t) and the Pulling Capacity, which is usually 1.5x the lifting capacity. Ensure the body is made of high-strength aluminum alloy or corrosion-resistant steel to balance weight and durability. The wire rope diameter must match the internal jaw mechanism precisely; using non-standard ropes will lead to slippage and safety hazards. Always check if the price includes the extendable operating handle and the standard 20-meter wire rope reel.
