- Nov 15, 2018-

Plain trolley for H or I beams driving is mainly driven by a bracelet, walking at the lower edge of the rail of the I-beam, with a chain hoist to form a bridge, single beam or cantilever crane, widely used in factories, mines , docks, warehouses, construction sites, etc., used to install machinery and equipment, lifting goods, especially for non-powered locations.


Plain trolley for H or I beams is safe and easy to maintain; compact structure, small installation size; convenient wheel spacing adjustment, suitable for a variety of I-beam; left and right wall panel hinge joint, under the action of gravity, can be adjusted by itself The height makes the four wheels evenly stressed; the transmission efficiency is high and the pulling force is small. It can be driven on corners with a small radius of gyration.


When installing H or I steel hand-cranked monorail, the number of adjusting washers on the inner side of the lifting ring to the left and right wall panels should be equal. However, in order to ensure the gap between the side of the rail and the edge of the roller, it is necessary to allow the number of adjusting washers on both sides of the lifting ring to be one piece. After installing on the track, pre-tighten the nut on the hanging shaft and hang the light load for trial operation. After the roller and the track are on, tighten the outer nut. Pay special attention to the fact that the nuts must be locked to each other.


Secondly, after the H or I steel hand push monorail is installed, the gap between the rolling sleeve and the track ground must be adjusted to reach the specified value. The specific adjustment method is to first loosen the nut, move the roller sleeve shaft to make the clearance reach the specified value, and then tighten the nut.
