Mechanical 4 Post VRC

• Load jam sensors suspend engine operation if the carriage or its load becomes jammed between landings.
• Motor control panel security requires personnel to activate a secure key switch before resuming lift operation following a load jam.
• Over-travel sensing switch suspends engine operation should the lift continue past the uppermost landing.
• Sensors on all lifting chains stop lift operation and movement if a slack chain is detected.
• Counterweight sensors serve as a back-up safety precaution to slack chain sensors by suspending engine operation when a counterweight is lifted out of the guide tube.
• Certified carriage brakes stop carriage falls in the very unlikely event of a sudden breakage of both lifting cables.
• Standard-issue shaft way barrier bar system improves personnel safety when carriage leaves the upper landing.
• Interlocked landing gates automatically lock once the vertical lift carriage leaves a landing and cannot be opened until the lift carriage returns to that landing.
• Gate status switches prevent lift operation while any gate is open.
• Minimum 3:1 structural factor of safety makes these lifts the most structurally sound in the industry.
• Compliance with recognized standards:
  • ASME B20.1 – Safety Requirements for Conveyors and Related Equipment
  • VRC Application Guidelines – as referenced by ASME B20.
  • NFPA 70 – National Electric Code
  • ASTM-A36 – Structural Steel Standard
  • ANSI Z535 – Safety Labeling Requirements
  • AWS D.1 – Welding Standards
  • Applicable portions of OSHA 29CFR1910 – General Workplace Safety

Maintenance and Warranty

• Heavy-duty SEW Eurodrive gear motor requires minimal service and maintenance.
• Maintenance-free carriage rollers require no lubrication.
• Eurodrive gear motor’s manual brake release overrides handle to help in lift start-up and trouble-shooting.
• Straddle design places much lower stress on the guide rollers, extending useful life.
• Autoquip offers a 1-year warranty on all parts and a 5-year warranty on lift structure as a promise that you’ve purchased the industry’s most reliable VRC.
