The new design of new generation product,which material adopt high-strength low alloy steels or Aluminum alloy,and the deflection and swing of crane is very little as the high-strength material.Lifting capacity could be maximum in a very small space due to its compact appearance.The small crane could be installed in the car box or some other places to perform mobile operation easily.Manual winch or electric winch with safety latch device could be configured to have lifting capcity of 100kg-500kg according to operating requirement.Choosing reasonable configuration could maximize function of crane to get the best using effect.
