Watch Out! The Machine Could be Overturned

Tags: used Hitachi excavator original used excavator2013-12-09

Used excavator, just as the name implies, is second hand used excavator. As we all know, the performance of a second-hand machine will not be as good as a new one. So, we should be more careful when a used excavator is working especially for the moment when the excavator is working on a slope. Excavators weigh several tons, so the consequence can be serious if it has an accident. There are some matters that we should pay attention to when the used excavator is working on a slope.

Before the used machine is working on the slope, make sure that except for the manipulation staff does not allow anyone to take a ride. While second-hand excavator is in charging or before starting the engine with different power, make the battery electrolyte melt. Before start, check whether the battery electrolyte is frozen and leak. Check whether the safety LOCK lever is in the LOCK position

First: don't turn on a slope or traverse slope. These operations could only be done in a flat place. When climbing the hill, please keep the distance between the digging bucket and the ground at 20-750 px, in order that when an emergency occurs, we can immediately drop the digging bucket to the ground to stop the excavator. If the tread skids or the excavator cannot climb the hill merely by the force of the crawler, don't utilize the tensile force of the bucket rod to help the used excavator to climb hill, the used excavator will be in the danger of tip-over. While going downhill, keep walking at low speed with a walking stick and the fuel control panel. If the gradient exceeds 15°, please reduce the engine speed. You must use this kind of operating mode or drive like this, i.e. if the machine skid or become unstable, you can safely stop at any time.

During the time of working on a slope, used excavator may not be out of balance. So we should pay special to that. Walk in the form of parallel up and down the slope as far as possible, instead of the horizontal way. When the digging bucket is loaded, do not rotate on the slope, if you must make rotation movement, you should build a platform for the used excavator in the operating area. The time when the engine stopped on the slope, please fell the scoop to the ground, place each lever in the neutral position, then restart the engine. As regard to a used excavator, potential safety hazard can be serious. More attention should be paid in the construction work, the moment you relax or take your attention away, landslides, electric shock, rollover accident may occur. Some accidents are caused by operators who ignore work specification. It is very necessary to keep this safety knowledge in mind. In this article, I focus on the matters that should be paid attention to when the second-hand excavator is working in slopes. I sincerely hope it will be helpful for you. This excavator is prominent in numerous excavators, if you want to buy one, hurry up, the used Komatsu excavator PC450-7 is the perfect choice.
