Background The City purchased an Arrow Pavement Breaker for the Water DiVlsion in March, 1975. In the last few years, the piece of equ1pment has been out of service much of the t1me, due to ser10US brake problems. Staff was anticipating the replacement of the equipment when the problem was apparently solved by the lnstallment of a hydraulic booster 1n the braklng system. In subsequent usage, the braking system again developed problems, although the vehlcle remained in service. Use of the pavement breaker cont1nued until October 6. 1980. when an accldent occurred on a hill on PieD Boulevard between 11th and 14th Streets. as the equ1p- ment operator applied the brakes to slow the vehlcle. Due to adJustment problems of the braking system. the veh1cle swerved and overturned, 1njuring the operator. Subsequent to the accident and the repalr of the veh1cle, 1t was declded to trailer the breaker to Job sites as it is ObV1ously too dangerous for operat10n as a mobile veh1cle 1n City traffic. Attempts fal1ed because of its great welght and the unequal dlstrlbution of that we1ght, WhlCh also contributes to its driving 1nstab11ity \ \. / ~-.s 'l AUG 1 1 f98f . d - .SubJect: Request for ~roval to Purchase a Replacement Payement Breaker e Page 2 Since the breaker 1S unsafe to drive to a job slte~ and Slnce it is lmpractical to haul lt to the Job sites by trailer~ replacement of the breaker 1S ind1cated. The machlne can either be replaced by purchaslng a new breaker or by renting one. (Rental machlnes are only ava11able wlth an operator.) Current rental cost is $60 per hour with a four-hour mlnlmum lncluding transportation to and from the site. Slnce our crews only break out pavement equal to the length of plpe they will install in a day 1n order to reduce complalnts~ est1mated rental costs will be S62~450 for the 81-82 flscal year. Prellminary estlmates indicate that a new breaker would cost $63~000 and be useful from 3 to 5 years or longer~ depending on use. The salvage value of the old machine may be S3-5~OOO. Recommendatlon It lS recommended that Councll authorlze Staff to obtain blds for a new pavement breaker and that the funds for such an expendlture be transferred from the ~ater D1V1S1on rental equlpment (Account (25-50Q-671-000-261) to a Capital Equipment Account (25-500-671-000-820).
