<div> <strong>First, choose a unipolar safety wire</strong> </div><div> As a trolley wire manufacturer, it is recommended to select the unipolar safety trolley wire as the power supply line. The unipolar trolley wire conductor adopts the H-type design. The inner groove is deep, and the current collector does not easily fall off and cause power failure. <br></div><div> <strong>Second, select heavy trolley wire</strong> </div><div> Although the gantry crane power is relatively small, it is recommended to use a 630A or more trolley wire because the gantry crane moves violently and requires high mechanical strength of the slide wire, while the heavy-duty trolley wire conductor has a large cross-sectional area and uses a single-hole lifting pylon as Fixtures can meet their strength requirements. <br></div><div> <strong>Third, the installation method selection</strong> </div><div> The gantry crane is used outdoors and there are two installation methods. One is an overhead installation mode, and the other is a trench installation mode. <br></div><div> <strong>Installation Notes:</strong> <br></div><div> Important installation instructions: <br></div><div> 1) Assembled suspension </div><div> Adjust the suspension bolts to ensure the straightness and horizontal parallelism error of each wire in the horizontal and vertical directions. Its value must not exceed 5mm. <br></div><div> 2) Wire connection </div><div> The guide rail and the conductive plate are connected with an abrasive cloth to remove the chlorinated layer and wipe clean; a layer of conductive paste with a thickness of about 0.2 mm is applied to reduce the contact resistance. <br></div><div> 3) Installation of power supply </div><div> In addition to the DHS-1600 and DHS-2000 markings, open the cable holes on both sides of the connection cover. The size of the opening is generally 2 mm smaller than the outer diameter of the cable. <br></div><div> DHS-1600 and DHS-2000 type slide wire, just according to the wiring diagram to determine the installation location to access. <br></div><div> 4) Installation of the collector </div><div> The length of the tractor (general type) is determined according to the number of poles of the current collector and the installation space; <br></div><div> For JDT type collectors, please refer to the current collector section in this chapter. JDS type collectors are usually mounted to the collector crossbar to maintain horizontality. <br></div><div> After installation, loosen the limit nut and remove the limit plate so that the collector moves freely up and down. <br></div><div> 5) Review </div><div> Check the parallelism of the sliding line and the lifting running rail, the requirement is less than 20mm, and tighten all the fasteners. <br></div><div> After 1 month of continuous use, tighten all fasteners once more. <br></div> <p><span class="keywords_replace"><a href="http://www.china-bearing-directory.com/rod-end-bearing/" style="color:unset;font-size: unset;font-family: unset;font-weight: unset;text-decoration:underline;">Rod End Bearing</a></span></p><p></p><p></p><p>Bearing Co., Ltd. ,http://www.china-bearing-directory.com</p>
