The electric push rod market is also a constraint to the development of strategic emerging industries, which is determined by the characteristics of high-end manufacturing industry. First, the product interest is high, like the cost of solar power generation is 34 times that of conventional thermal power; Second, high requirements for service facilities, such as new energy vehicles if there is no corresponding charging facilities, the car can not run; Third, the market trust bottleneck, that is, after the domestic new things go in, consumers do not trust.

The electric push rod type cantilever crane has initially formed the R&D and manufacturing system of main engine products, basic technology and functional components at the international frontier level. China's equipment manufacturing industry should focus on industrial optimization and upgrading, shift from production to service, consolidate the industrial base, solve the problem of lagging development of basic components, foster emerging industries, and improve the capacity for independent innovation. From large to strong "national high-end equipment manufacturing industry development concept, at the same time, our construction machinery industry only exert the cluster effect and brand effect, to walk out of a unique international road. It indicates that the intellectual property barriers of foreign leading enterprises in the field of hoisting machinery have been gradually conquered by Chinese independent intellectual property rights. Domestic construction machinery enterprises have broken the monopoly of foreign crawler cranes for 3000t class, and domestic super-large tonnage crawler cranes have been published. Standing on the forefront of the global hoisting machinery industry, at the same time, this also marks the level of Chinese construction machinery research and development into a new height.

The electric push rod takes the motor as the power source and rotates forward through the motor to make the hydraulic oil output pressure oil through the two-way gear pump, which is sent to the working oil cylinder through the oil circuit integrated block to realize the reciprocating movement of the piston rod. When the electric push rod works, if the external force of the piston rod exceeds the rated output force or the piston has reached the end point, the motor is still rotating. At this time, the oil pressure in the oil circuit increases to the set pressure, and the relief valve can overflow quickly and accurately to realize automatic overload protection. The motor is running, but it will never burn out. The pressure self-locking mechanism is designed in the oil circuit integrated block of the electric push rod. The motor stops rotating, the piston rod immediately stays in a certain position, and the pressure oil is in a state of pressure preservation. According to the site installation space and user usage, the electric push rod can have a variety of structural forms, see the electric push rod outline size diagram for details, and can also be customized according to user requirements. The motor drives the positive and negative output of the pressure oil through the positive and negative rotation of the two-way hydraulic pump, which is sent to the cylinder through the hydraulic control valve, and also realizes the reciprocating movement of the piston rod.

Many electric push rod businesses have seen the profit of electric push rod, so they are using a variety of means to package their own products, to fight for the most money. If some bad businesses do not comply with the healthy competition in the market, in the material of the electric push rod fraud, in order to obtain more profits, this is harmful to the use of consumer behavior, hinder its long-term development. The motor rotation is not uniform, the motor rotation speed is kept constant in theory, if there is an uneven speed, generally the electric push rod is not fixed, has been in a state of shaking, and check whether the pulley wear leads to inconsistent resistance when rolling.
