2, the operating unit of electric block adopts no wheel rim operation wheel and track adjusting wheel, the contact surface that has strengthened wheel and guide rail in service, and replace wheel rim with guide wheel, can not produce cliding friction in any case, operation noise and running wastage have been reduced, prolonging the life-span of girder and wheel, is present best environmental protection and energy saving product, power saving, province's steel;
3, end carriage adopts the J shape steel tube, has not only alleviated weight, and has saved production man-hour, and moulding is more attractive in appearance;
4, a wheel operating unit employing nothing shelves limit 45# steel cylinder wheel, and add track adjusting wheel control sideslip, power saving, saving steel, reduction noise, raising life-span.
By above-mentioned improvement, complete machine weight can alleviate more than 12%, if the whole nation all adopts this structure, steel can be saved more than 5,000,000 tons every year in the whole nation, is equivalent to increase build 5,000,000 tons of steel mills.
