mg娱乐4355路线在购买时要注意哪些事项?

日期:2020-08-10   来源:
由于挖掘机自身的缺陷限制了它的工作范围,而往往有很多施工现场需要挖掘机扩大施工范围,但现有的大小臂满足不了现场的要求,mg娱乐4355路线(加mg娱乐4355路线)也就应需而生。那么mg娱乐4355路线在购买时要注意哪些事项?今天mg游戏平台小编就带大家来了解一下:
Due to the defects of excavator itself, its working range is limited, and there are often many construction sites that need excavator to expand the construction scope, but the existing boom and boom can not meet the requirements of the site, so the long arm excavator (extended arm excavator) is born. So what should be paid attention to when buying long arm excavator? Today, I'd like to take you to know:
购买挖掘机时要考虑自身现有设备的匹配性,包括挖掘机作业效率和现有设备作业效率的匹配,比如小型挖掘机虽然价格低,但与大翻斗车不匹配,相当于“小马拉大车”同理也应避免“大马拉小车”造成不必要的浪费。
When purchasing excavators, it is necessary to consider the matching of their existing equipment, including the matching of excavator operation efficiency and existing equipment operation efficiency. For example, although the price of small excavator is low, it does not match with large dump truck, which is equivalent to "small horse pulling cart". Similarly, unnecessary waste caused by "big horse pulling car" should be avoided.
用户应意识到购买挖掘机的收益情况,若能接到工程,很快就能收回成本,但在选择时可以根据资金情况考虑多种购买方式、分期付款、银行按揭、租赁购买等方案,如果资金允许可以优化自己的设备结构,从而提高自身承包大型工程项目的竞争力。
Users should be aware of the benefits of purchasing excavators. If they can receive the project, they can recover the cost quickly. However, they can consider various purchase methods, installment payment, bank mortgage, lease purchase and other options according to the capital situation. If the funds allow, they can optimize their own equipment structure, so as to improve the competitiveness of large-scale engineering projects.

(1)行走部分选型时应注意事项
(1) Precautions for selection of walking part
履带式挖掘机使用范围广,所以相对较多。其特点是牵引力大,接地比压低(一般为0.04~0.15MPa),稳定性好具有良好的越野性能和爬坡性能,比较适合应用于作业环境恶劣条件下的施工。根据地面的情况一般选用标准型履带式挖掘机;若工况地面的承载能力强,且地面凸凹不平则选用窄履带板型的挖掘机;若工况地面的承载能力较差,且土质疏松则选用履带加长,履带板加宽型的挖掘机;若是在沼泽地施工的工程,则应选用沼泽地专用履带板型挖掘机。但应注意并不是履带越长越好,履带板过长或过宽都会加速磨损,支重轮、引导轮和驱动轮也会受到频繁的外力冲击过早地到达使用寿命;同样,履带过短履带板过窄的挖掘机如果在不适合的条件下使用,也会过早的损坏。
Crawler excavator is widely used, so it is relatively more. It is characterized by large traction force, low grounding pressure (generally 0.04 ~ 0.15Mpa), good stability, good cross-country performance and climbing performance, which is suitable for construction under harsh working conditions. According to the situation of the ground, the standard crawler excavator is generally selected; if the bearing capacity of the ground is strong and the ground is uneven, the excavator with narrow track plate is selected; if the bearing capacity of the ground under working condition is poor and the soil is loose, the excavator with longer track and wider track plate is selected; if the project is constructed in marshland, the special crawler plate type for marshland shall be selected Digging machine. However, it should be noted that the longer the track is, the longer or wider the track shoe will accelerate the wear, and the roller, guide wheel and driving wheel will also be impacted by frequent external force and reach the service life prematurely; similarly, the excavator with too short track track track and narrow track shoe will be damaged prematurely if it is used under unsuitable conditions.
(2)工作装置部分选型时注意事项
(2) Precautions for selection of working device
一般情况下,挖掘机工作装置部分包括动臂、斗杆、铲斗以及相关的油缸和液压管路。因挖掘机的工作装置部分更换比较方便,所以可以根据不同的工作场合更换相应的工作装置,以满足各种工况的使用需要。
Generally, the working device of excavator includes boom, stick, bucket and related cylinder and hydraulic pipeline. Because it is convenient to replace the working device of excavator, the corresponding working device can be replaced according to different working conditions to meet the needs of various working conditions.
另外,铲斗部分也可以更换成破碎器,充分运用于大块岩石的破碎,小工作量破碎相比火药爆破安全很多,操作方便而且效率很高。铲斗也可以更换成抓叉、抓斗,用于一些废旧物品的处;更换成液压剪,充分运用于楼房等建筑物的拆迁,对从事市政工程的单位或个人是一个很好的投资方向。
In addition, the bucket part can also be replaced by a crusher, which is fully used in the crushing of large rocks. Compared with gunpowder blasting, small workload crushing is much safer, easy to operate and highly efficient. Bucket can also be replaced by grab fork, grab bucket, used for some waste materials; replaced by hydraulic shear, fully used in the demolition of buildings and other buildings, is a good investment direction for units or individuals engaged in municipal engineering.
