In oil well stimulation, transfer cases are widely used to drive the
winch, rotary table, chassis and many other devices and truck parts.
With transfer cases, the winch and rotary table can work both
independently and simultaneously. Apart from this, the rear axle and
front axle of the chassis can also be driven individually as well as at
the same time according to the road conditions: if the road is smooth
enough, the front axle should be released; but if the road is rugged or
muddy, the front axle should be connected. Although this driving way
increases technical complexity, it can prevent the vehicle from being
stuck into sunken roads. Besides, it can alleviate tyre wear. Our
transfer cases are featured by compact structure and reliable torque
transmission.
