We are analyzed the available designs grabs for developing frozen granular materials, identifying their modernization. We are improved design of serial grapple what used overload frozen pyrite flotation in the open warehouse storage. We took into account the previously developed design grabs, as well as existing methods of calculating parameters grab. The changes in the resistance moment in the development of the frozen scoop pyrites, depending on moisture content, as well as exposure to vibration. The expediency of including the destruction of the resistance moment clamped jaws grab the frozen crust material. The technical solutions to improve the reliability grapple overload frozen pyrite flotation, providing energy savings for scooping material. The design of the battery power grab jaws opening and lowering the lower cross member, presented an engineering method for calculating the battery power. Balance sheet analysis shows the effect of the torque spring on the battery level of disclosure jaws. Shown to reduce the implementation effort cutters grapple with the power to implement the frozen layer of material. The necessity of opening the site kinematic coupling in the energy storage - the hinge beam jaws grab.
