The static load test shall be carried out according to the following procedures and requirements. Park the crane at the column. Choyamba, start the hoisting mechanism to conduct no-load lifting and lowering operations, and make the trolley run back and forth along the whole journey. This no-load trial operation shall be carried out no less […]

The winter maintenance of construction machinery is of great significance. Especially in the northern regions where winters are long and the temperature remains low for extended periods. When construction machinery is used in winter, the cold climate can easily lead to difficulties in starting internal combustion engines, freezing of cooling water and electrolyte, intensified wear […]

The reasons for the downward deflection of the main girder of overhead cranes are multifaceted and should be analyzed according to specific circumstances. Nthawi zambiri, issues can arise from design, kupanga, mayendedwe, kukhazikitsa, and use. (1) The Impact of Unreasonable DesignIn the past, China followed the Soviet standards. The static stiffness of the main girder […]

Mosasamala mtundu wa makina, mafuta odzola osiyanasiyana amaletsedwa kusakaniza kuti agwiritsidwe ntchito, ndi ochepetsa nawonso. Kwa ochepetsa, malo a pulagi mlingo wa mafuta, kukhetsa pulagi, ndi kupuma kumatsimikiziridwa ndi malo awo oyika. Zikafika pakugwiritsa ntchito, kuyendera, ndi kukonza mafuta opaka muzitsulo zochepetsera, […]

(1) Requirements for Elastic Base Plates The elastic base plates are made of rubber sheets, and their properties should meet the following requirements: a Shore hardness of 70 – 80 madigiri, a tensile strength greater than 130 kg/cm², an elongation at break greater than 300%, and a compressive elastic modulus of 700 – 1200 kg/cm². […]

Kuyika mayendedwe a crane ndi njira yofunika kwambiri yomwe imawonetsetsa kuti ma crane akuyenda bwino ndikuyenda bwino.. Mfundo zotsatirazi zikufotokoza ndondomeko ya kukhazikitsa: 1. Kuyika Mzere Pogwiritsa ntchito nsonga yoyikira girder ngati cholembera, tumizani theodolite kukhazikitsa mfundo zoyambira. Pa mtunda wa 60mm kuchokera njanji centerline, […]

Chiyambi Kuyika pansi ndi gawo lofunikira pachitetezo cha crane, kuonetsetsa chitetezo cha onse ogwira ntchito ndi zipangizo ku zoopsa zamagetsi. Kuyika pansi koyenera kumachepetsa kuopsa kwa kugwedezeka kwamagetsi, moto, ndi kuwonongeka kwa zida popereka njira yodalirika kuti mafunde amagetsi aziyenda bwino padziko lapansi. Bukuli limapereka chithunzithunzi chokwanira cha zofunikira zoyambira […]

Ine. Zizindikiro Zogwirizana za Oyendetsa ndi Ma Signal Personnel Gantry crane opareshoni ndi ogwira ntchito amasigino ayenera kugwiritsa ntchito ma siginecha okhazikika komanso ogwirizana kuti awonetsetse kulumikizana bwino komanso kulumikizana.. Oyendetsa ayenera kukwera kapena kutsika kanyumba koyang'anira pogwiritsa ntchito makwerero osankhidwa. Musanagwiritse ntchito magetsi, wolamulira ayenera kutembenuzidwa ku malo osalowerera. Pansi pa kanyumba iyenera […]

Proper lubrication and maintenance of the crane’s walking mechanism are critical for ensuring the equipment’s longevity, kudalirika, and safe operation. This document provides comprehensive guidance on the lubrication and care of the crane’s walking components, including the reduction gears, wheel bearings, and open gear systems. Initial Setup and Reduction Gear Lubrication When the walking mechanism […]
