With the development of building decoration and construction, excavator elongated arm has also developed rapidly, because it is often used in construction, many people do not know how to choose manufacturers, and its scope of use is not very clear, so let the company to answer for us.
一， 先从网络了解：随着互联网的不断发展，信息传播的渠道已经发生改变，网络渠道是目前快捷便利的方式之一二， 电话咨询：通过和它的生产厂家营销人员的沟通，从营销人员的专业知识和待人处世的态度做出初步的判断三， 侧面了解：通过行业的朋友熟人了解该企业的规模实力，技术水平，产品性价比和售后服务情况，金杯银杯不如顾客的口碑，金奖银奖不如顾客的夸奖四， 实地考察，货比三家：挖掘机加长臂作为一个中长期的投资，关系到工程，实地考察必不可少。通过实地考察，对厂家的实力、技术水平、产品质量、售后服务情况有个详细的了解，让你买回去以后用得放心。
First, from the network: with the continuous development of the Internet, the channel of information dissemination has changed. Network channel is one of the fast and convenient ways at present. Telephone consultation: through communication with its manufacturers and marketing personnel, make a preliminary judgment from the professional knowledge of marketing personnel and attitude towards life. Third, understand from the side: through friends and acquaintances in the industry. Understanding the scale strength, technical level, product cost performance and after-sales service of the enterprise, the reputation of customers is worse than gold cup and silver cup, and the praise of customers is worse than gold award and silver award. Through on-the-spot investigation, we have a detailed understanding of the strength, technical level, product quality and after-sales service of the manufacturer, so that you can rest assured when you buy it back.
Let's look at the scope of its use.
Excavator elongation arm has two section excavator elongation arm and three section excavator elongation arm, two section excavator elongation arm is mainly suitable for earthwork foundation and deep cutting excavation, River silt removal; three section excavator elongation arm is mainly suitable for high-rise building disassembly and other projects. According to leverage principle and mechanics principle, the force of the extended arm excavator is less than that of the original excavator, and the construction should be avoided as far as possible.
After knowing these knowledge, we will know what kind of excavator can be refitted into a new one. It is not recommended to refit, because after refitting into an extended arm excavator, the load of the excavator will increase, and after-sales service disputes will easily arise with the original plant without overdue warranty period. Fifty percent of the new excavators are not recommended to be refitted, because the service life of the machine is relatively old, and all aspects of performance will be reduced. Back, plus the elongated arm itself has a certain weight, it is difficult to give full play to the efficiency of the elongated arm excavator, the better is 5-8% of the new excavator into the elongated arm excavator.
Above is some knowledge about the extended arm of excavator provided by the extended arm. After reading the article, we believe that there are great gains. If you still have questions after reading the article, please pay attention to the update of our company's website to understand.
