Shandin's new small excavator SD12U has been fully upgraded with double-sided hydraulic safety locks to ensure safe operation when getting on and off the vehicle on both sides. The control system has been fully upgraded to add the telescopic and earth-moving shovel operating levers which are beautiful and easy to operate, and the newly upgraded cylinders are located on the top of the arm frame, which prevents the cylinders from being bumped when they are working, and the hidden oil pipe design makes the appearance neat and beautiful.
