Features of Quick Connector made by RIVER
①Using high-strength manganese steel and structurally integrated mechanical design, it is durable and suitable for the assembly requirements of excavators of various tonnages.
②The cab is equipped with an electric switch to replace the high-cost oil pressure with electricity, which is convenient for the driver to operate.
③A hydraulic control check valve and a mechanical locking safety device are installed on each oil cylinder to ensure that the quick connector can work normally when the oil circuit and circuit are cut off.
④A safety pin protection system is installed on each quick connector to ensure that the quick connector can work normally when the quick connector oil cylinder fails, which plays the role of “double insurance”.
