Crane
Cranes are efficiently used to lift loads and carry them from one place to another. Cranes can be used in in-plant carriage systems or on vehicles.
Cranes are able to carry and place loads multi-directionally and sensitively with specially-designed drive systems. With brake and driving control equipment integrated thanks to synchronized operation of crane and trolley, solutions with high operation success and high safety considerably contribute to efficiency of factories.
PCS series products provided by PGR Drive Technologies have lifting capacity from 1 ton up to 60 tons and comply with FEM – ISO standards. In addition to use with double-speed (2-12 poles) motors that have IP55 protection class, they offer perfect driving with frequency inverter. Our crane gear units with low corrosion and silent operation features are available in aluminum (EN-AB-46100) and cast iron (GGG 40-50) options.
Also preferred in industrial applications, PH/PB series gear units can be used for lifting processes at torque rating up to 480 000 Nm. These bodies ensure maximum safety in high power needs and operating conditions.
PGR Drive Technologies provide solutions with parallel shafted PD/PM series and bevel PKD series to ensure gantry and bridge movements in cranes securely and effectively.
