what is the issue if only one of the arms moves very slow... the other one moves at the right speed

1 comments:
Mr. Anderson
May 29, 2025

One possible cause is that the muscle on the slower-moving arm is generating less force or power, possibly due to fewer muscle fibers being activated. This could result from weaker neural signals, leading to fewer motor units being recruited, or from physiological limitations such as fatigue or reduced muscle efficiency. Differences in load or resistance on each arm could also affect the speed of movement due to the force–velocity relationship of muscles.

    NSTALLATION Introduction This Manual provides the Installation, Periodic Mainte- nance, Troubleshooting, Service and Specifications for Cascade E-Series Revolving Clamps. E-Series Clamps are designed for three-shift-a-day continuous-duty operations with minimal maintenance. They offer exceptional visibility for the lift truck driver and provide optimized clamp force and load handling.
