Operator in a very soft ground excavation work, when to reinforcement edge, used excavators outlets, a large enough cushion board is a good method, used excavators direct prices, but also on the side away from the edge of the excavator to do Good track drive fixed. Excavator Excavator is not to do more than the weight lifting work. Crawler excavators work is very dangerous on the very steep slopes, in particular, to avoid work on slopes above 10 degrees, so we have to construct a horizontal surface and then continue to work. Do not do digging arm swing action on the slopes, the focus changed to prevent lead to instability tipping body. Especially when loaded in the bucket of the bucket should not leave the ramp surface if conditions permit, you can do the regular work of the fuselage on the slopes. Used excavator plunger injection pump test of ridicule, many engineering machinery maintenance personnel do not pay attention to check construction machinery piston stroke margin. The so-called plunger stroke margin refers to the amount of movement of the plunger by the cam on the camshaft after top dead center supremacy, but also to continue upward. Adjusted supply start time, the reason also check the travel allowance, travel allowance because the plunger and plunger sleeve worn related. After the plunger sleeve worn, used excavators direct factory, the plunger up to more exercise period to start oil, so that the oil supply start time delayed. When screwing the adjusting bolt to adjust or switch thicker pads, pads, Shanghai second-hand excavator direct sales network, the lowest position of the plunger on the move, the plunger stroke margin decreases. Therefore, when the fuel pump engineering machinery maintenance, debugging, first check the travel allowance, to determine whether the fuel pump also allows you to adjust. Used excavator direct _ _ Shanghai Jin Hao used excavators used excavators direct sales network provided by Shanghai Used Construction Machinery Co., Ltd. Jin Hao. Used excavator direct _ _ Shanghai Jin Hao used excavators used excavators Direct is Shanghai Jin Hao Used Construction Machinery Co.
