Creep Drive Design for Guardrail Truck Application

A customer of Cotta’s has has been using this creep drive design for over 10 years.  These units shown in the picture are getting close to shipment and will be used in a guardrail truck application.  The creep drive allows the vehicle to creep along at very low consistent speeds, regardless of the engine speed.  This in turn allows the auxiliary systems to utilize the power needed to perform the work needed effectively.  The vehicle is then able to drive at a normal speed once the system is disengaged.

Specifications:

• Ratio 3 : 1
• Max Torque: 1250 ft lbs input PTO mode, 12500 ft lbs thru mode
• Approximate Weight: 390 lbs
• Oil Capacity: 12 quarts

Cotta has a creep drive model #Tr2273, which is a creep drive gearbox designed to provide precision vehicle speed control by using a hydraulic motor to rotate the vehicle drive shaft.  To learn more, click on Creep Drive.
