The Star 4 vehicle restraint offers a higher level of automation and convenience. The restraining arm is raised and lowered automatically at the touch of a button by a linear actuator drive system. The programmable logic controller (PLC) offers more flexibility to meet the evolving needs of your facility.
The Kelley STAR 4 vehicle restraint is designed to engage the rear impact guard of a vehicle and hold the vehicle at the loading dock during the loading and unloading process.

Benefits

Non-Impact Operation

 N/A All Kelley STAR vehicle restraint models are based on non-impact operation, an advantage that offers many benefits:
  • No rear impact guard damage.
  • Longer service life.
  • Better, more reliable performance.
  • Less maintenance.
  • Compatible with NHTSA regulation rear impact guards.

Superrior Communication

 N/A STAR restraints offer positive communication systems to help avoid one of the biggest dock safety problems - poor communication between dock workers and vehicle drivers:
  • Exclusive hook-mounted sensor bar senses actual contact between the throat of restraint arm and the vehicle’s rear impact guard.
  • Standard LED exterior and interior lights.
  • Easy-to-see printed signs.
  • Audible alarms.

Low Maintenance

 N/A The entire line of STAR vehicle restraints is engineered to minimize maintenance requirements and costs:
  • No alignment.
  • No scheduled adjustments.
  • No lubrication.

Simple Design

 N/A STAR vehicle restraints exhibit unmatched design simplicity, another advantage with several benefits:
  • Fewer moving parts, fewer problems.
  • Easier, more reliable operation.
  • Reduced training requirements.
  • Lower maintenance costs (labor and parts).
  • Longer service life.
