Contamination Control
The Riggs Cat Little Rock hydraulic facility is climate controlled to minimize contamination. Current hydraulic systems are designed with ultra-tight specifications, which means that any intrusion by contaminates can cause failures or reduce system life. Riggs has stringent standards of cleanliness in order to minimize, with the intent to eliminate, component-killing contaminates.
Valves
The Riggs Cat team has the knowledge, parts and repair capabilities to save you time and money on your construction equipment valves. An extensive selection of valves and related parts are in stock to ensure fast turnaround. All parts are tested before re-installation to ensure proper execution of hydraulic repairs.
