Do you know the orange peel grab?--- Double and four rope orange peel grab

Double rope orange peel grab

The double rope orange peel grab is an effective tool for loading and unloading ore, ore powder, pig iron, lump coal, and other massive bulk cargoes under various harsh environments under a double-drum crane.

The double rope orange peel grab is composedof upper bolster, struts, lower bolster, upper and lower wheels, bucket flaps, etc.

The working principle of the double rope orange peel grab: the two drums of the crane respectively come down with two wire ropes, one wire rope is connected with the upper bolster of the grab (called the support rope). The other is connected to the steel wire rope wound on the grab pulley block (called the opening and closing rope). The support rope remains unchanged, the opening and closing ropes are lowered, the grab opens and discharges. The grab is placed on the material and the closing rope rises, and the grab closes to grab the material. The closing force of the grab bucket is realized by the pulley block above and below the grab bucket. The pulley block magnification is generally 3~5, and the pulley block magnification is large, and the digging force is large.

Connection with crane: the two steel wire ropes of the grab bucket can be connected to the steel wire rope on the crane respectively.

Four rope orange peel grab

The four rope orange peel grab is an effective tool for loading and unloading ore, ore powder, pig iron, lump coal, and other massive bulk cargoes under various harsh environments under a twin-double-drum crane.

The four rope orange peel grab is composed of gimbal, upper bolster, strut, lower bolster, upper and lower wheels, bucket flaps, etc.

The working principle of the four rope orange peel grab: The two double drums of the crane respectively drop four wire ropes, two wire ropes are connected with the gimbal of the upper bolster of the grab (called support ropes), The other two are connected to the two steel wire ropes wound on the grab pulley block (called as opening and closing ropes). The support rope remains unchanged, the opening and closing ropes are lowered, the grab opens and discharges. The grab is placed on the material and the closing rope rises, and the grab closes to grab the material. The closing force of the grab bucket is realized by the pulley block above and below the grab bucket. The pulley block magnification is generally 3~5, and the pulley block magnification is large, and the digging force is large.

Sum up:

The characteristics of the grab are: simple structure, convenient operation, high efficiency and few failures.

The performance of the orange peel grab is that under the condition of rated lifting weight, under the same pulley block multiplier, without affecting the excavation, without affecting the service life, the dead weight is reduced, the grab volume increases, and the production efficiency is improve. In the 1970s, the grabbing ratio of the orange peel grab for grabbing ore was 1:1.2. After decades of continuous research by technicians, the technical performance of the orange peel grab has been greatly improved.
