        1.Patented technology of wrench speed self-adjustment, tightening bolt in high-speed when torque is lower; and when torque is heightened, automatically switching to low speed high torque; effective and stable torque output.

        2.Torque adjustment is easy and intuitive,night lighting available, and around-the-clock operation.

        3.Torque output error < ± 3%, exceeding national railway standard(< ± 5% error); good performance for line operation.

        4.Dual-head type wrench adopted; high efficiency; easy to operate and regulate; light weight.

        5.Automatic alignment: less than 15mm's anchoring error, and universal sleeve can be aligned automatically; simultaneous operation can be realized with double-sleeves.
