Cuestiones de configuración y mantenimiento con el brazo Provid Iso-Elastic steadicam
Tiene 21 años. Es posible que el equipo y los precios hayan cambiado desde entonces.
Lo que encontró el hilo
- Al configurar un brazo Provid Iso-Elastic, ajustar el antebrazo (gimbal extremo) a horizontal primero, luego establecer el brazo superior para seguir el antebrazo para que ambos se muevan juntos.
- Provid arms from early production batches commonly experience bearing failures due to undersized plastic lavarers at the hinge joints, which creates excessive twisting forces across the bearings and can cause them to shatter or fall out.
- El problema de la fuerza retorcida en los cojinetes es causado por un espaciado inadecuado y se puede abordar a través de una modificación de cojinete que también mejora la suavidad del brazo.
- Some Provid arms have suffered cable snaps and metal trunnion fractures, potentially related to increased torque from socket block upgrades.
- Later production batches of Provid arms shipped with stronger bearings than earlier models.
- The Provid arm is described as stiff and challenging to operate compared to other arms, with design compromises made to achieve a low price point, including the use of undersized bearings that gum up under load.
- Do not continue using a Provid arm if bearings are damaged, as the arm may be rubbing metal-to-metal internally.
Depende de
- The bearing failure issue applies specifically to early production Provid arms; later batches had stronger bearings.
- Reports of cable snaps and trunnion fractures may relate to specific upgrades or modifications rather than inherent design.
- The description of the arm as stiff is stated as subjective opinion based on comparison to other arms.
- A detailed historical disassembly report that may contain additional technical information is mentioned as lost.
