          長臂挖掘機租賃的伸展臂不能舉起?

          長臂挖掘機租賃使用時,長臂挖掘機的動臂和前臂不能抬起或伸出,為什么長臂挖掘機的伸長臂不能抬起?一般來說,故障基本上是手臂和前臂的曲軸傳感器損壞,因此在使用挖掘機時,必須防止手臂挖掘機因過度操作而傾斜或碰撞。傳感器發生這樣的沖突容易破損,發生故障或接地短路問題。

          When renting a long arm excavator, the boom and forearm of the excavator cannot be lifted or extended. Why can't the extended arm of the excavator be lifted? Generally speaking, the fault is mainly caused by damage to the crankshaft sensors of the arm and forearm. Therefore, when using an excavator, it is necessary to prevent the arm excavator from tilting or colliding due to excessive operation. Sensors with such conflicts are prone to damage, malfunctions, or ground short circuits.

          當然,傳感器也有正常的可能性,但是如果機器不能正常工作挖掘機租賃的驅動管可能會損壞。在這種情況下,我們只能重新修理,更換損壞的零件。在長臂挖掘機租賃的操作過程中,如果發現長臂緩慢,就必須檢查密封是否有問題,釋放液壓油,啟動發動機,如果沒有液壓油,就說明活塞密封的良好性。

          Of course, there is also a normal possibility for sensors, but if the machine cannot function properly, the drive pipe rented by the excavator may be damaged. In this case, we can only repair and replace the damaged parts. In the operation process of renting a long arm excavator, if the long arm is found to be slow, it is necessary to check the seal for any problems, release hydraulic oil, start the engine. If there is no hydraulic oil, it indicates the good sealing of the piston.

          密封無效的話,這是內部泄漏,需要修理。另外,檢查吸氣閥是否正常,他能保護我們的油路,從油箱吸油補充壓力,能很好地保護油路。

          If the seal is ineffective, it is an internal leak that needs to be repaired. In addition, check if the suction valve is working properly. It can protect our oil circuit and replenish pressure by sucking oil from the tank, which can effectively protect the oil circuit.

          伸縮臂斗桿擁有比加長臂挖掘機更大的挖掘機深度,鏟斗也更大,因此效率遠高于后者。同時需要的擺動空間更少,適合緊湊的位置,也不需要道路。當然,這種工具也不是隨便一臺挖掘機就可以安裝的,通常只用于20噸以上的挖掘機。加長臂挖掘機租賃

          The telescopic arm bucket has a deeper excavator depth and a larger bucket, making it much more efficient than the extended arm excavator. At the same time, it requires less swing space, suitable for compact positions, and does not require roads. Of course, this type of tool cannot be installed on any excavator and is usually only used on excavators weighing over 20 tons. Leasing of extended arm excavators

          平衡閥有故障或油管中有空氣也是伸臂不能回縮的主要原因,如果因進油管產生泄漏而進氣,可先排除泄漏,然后反復拉推操縱桿,使氣體沿回油路回油箱;若平衡閥有故障,須緩慢地擰開從平衡閥到下腔進油口的空心螺栓,讓伸縮缸下腔液壓油從接頭縫隙中慢慢流出,這時伸縮臂在自重作用下會自動縮回,然后再檢查平衡閥控制油口小孔是否堵塞。

          The main reason for the inability of the arm to retract is due to the malfunction of the balance valve or air in the oil pipe. If there is a leak in the oil inlet pipe and the air enters, the leak can be eliminated first, and then the control lever can be repeatedly pulled and pushed to allow the gas to return to the oil tank along the return oil path; If there is a malfunction in the balance valve, slowly unscrew the hollow bolt from the balance valve to the oil inlet of the lower chamber, allowing the hydraulic oil in the lower chamber of the telescopic cylinder to slowly flow out from the joint gap. At this time, the telescopic arm will automatically retract under its own weight, and then check whether the small hole of the control oil port of the balance valve is blocked.

          樁基礎由基樁和連接于樁頂的承臺共同組成。若樁身全部埋于土中,承臺底面與土體接觸,則稱為低承臺樁基;若樁身上部露出地面而承臺底位于地面以上,則稱為高承臺樁基。建筑樁基通常為低承臺樁基礎。高層建筑中,樁基礎應用廣泛。

          The pile foundation consists of a foundation pile and a cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom surface of the cap contacts the soil, it is called a low cap pile foundation; If the upper part of the pile body is exposed to the ground and the bottom of the pier cap is above the ground, it is called a high pier cap pile foundation. Building pile foundations are usually low cap pile foundations. Pile foundations are widely used in high-rise buildings.
