The hydraulic systems of the IRON FIST cranes are characterized by two important factors: Low working pressure; Larger pipes diameter.
Both allow for increased life and lower maintenance of the hydraulic system. Low pressure avoids heavy strain on the sealing system, the increased diameter of the pipes allows to keep the oil temperature low and to have a high operating speed since the first maneuvers. All cranes are equipped with stainless steel pipes and stainless steel fittings. The flexible hoses are used only in the articulation point for reduce at minimum the maintenance, reducing also the maintenance costs.
All cranes are equipped with pressure filter for avoid the contamination of the crane hydraulic system.
