Bridge weight limit is serious business | Ledger Independent

Officers with Kentucky State Police Division of Commercial Vehicle Enforcement were in Maysville late Monday and all day Tuesday, monitoring traffic on the Simon Kenton Memorial Bridge. The officers brought portable scales with them to weigh vehicles, particularly trucks suspected of exceeding the bridges weight limit, and set up near the Mason County Public Library. Last week, the Kentucky Transportation Cabinet reduced the weight limit on the historic bridge crossing the Ohio River after a recent inspection revealed some issues with the bridge’s cables. While the bridge is not in any immediate danger, engineering analysis shows the reduced weight limit is needed as a traffic safety precaution and to prevent possible further damage until the structure can be repaired, officials said. “The damage we found on several hanger cables warranted the weight limit posting,” said KYTC spokesperson Allen Blair. If the new 3-ton limit is not enforced, state officials said the bridge could be closed to traffic until repairs can be made. “We understand that the lower weight limit impacts a number of travelers, particularly commercial vehicles, but the change is very important to ensure traf...

What this means is motors have more heat generated in them when they start than when they are running. It takes time to dissipate the extra heat. The heat can dissipate as the motor runs (the fan in a fan-cooled motor helps dissipate this heat) or as the motor sits in a non-running condition. The important thing is to dissipate the starting heat rather than increase the motor temperature significantly through repeated starts placed too close together. If the cycle of start/stop/start is too short, we call that short-cycling. And it’s deadly to motors. Most manufacturers have starting frequency figures for the motors they build. If you aren’t sure how long to wait between starts, contact the manufacturer for the recommended time. Sometimes, the controls for motor-driven equipment will state the minimum time between starts. Sometimes, the controls will actually limit th...
