◆ Based on the load situation and combined with the CMHO chain traction control system, large-scale projects can be implemented according
to corresponding safety requirements.
◆ Customized solutions tailored to individual customer needs can meet various application scenarios, further improving the world's most
comprehensive chain system product matrix – CMHO's ingenuity.
◆ Strictly following the D8Plus standard configuration, equipped with dual independent braking systems, including service brakes and safety
brakes. Both use a DC braking system for their brakes, which operates based on the principle of static current. When the voltage is interrupted,
the brake will automatically activate the braking action, ensuring that the load can be reliably fixed under any operating conditions.
◆ The chain transmission system is equipped with an overload anti slip clutch, which can effectively protect the driving device.
◆ W12-U D8 Pro/D8+Pro can provide electronic limit function, which is a safety device unique to CMHO. When the limit contactor is touched
when rising or falling to the limit, it can stop in a timely and effective manner to danger.
◆ A chain traction device that meets the D8Plus standard.
◆ Load chain operating coefficient -8 (corresponding to IGVW SQP2 2019-04)
◆ Control line plug specification: 1 meter CEE-16A/4 connecting cable.
◆ Equipped with 2 handles.
