User manual CATERPILLAR CM845 BROCHURE

[. . . ] The CM845 screed offers variable frequency tamper bars, vibratory screed plates, double-width extenders, LCD operating display, and electric heat for high performance on all types of mix designs and job sites including interstates, highways, airports. [. . . ] The adjustable speed tamper bars ensure smooth flow under the screed plates, while the vibratory system provides additional compaction for optimal mat quality. The double-width extenders maximize job site versatility by delivering a wide paving range to meet application requirements. An intuitive LCD display keeps the operator informed of screed plate temperature, tamper bar speed, vibratory speed, and screed counter-balance pressure. The easy-to-use electric screed heat system quickly gets the plates and tamper bars up to the ideal operating temperature for fast starts. ­ Sensor height can be individually adjusted ­ Easily move to the next starting point without disassembly.
