RACE Air Conditioner Jacks

The RACE AC Air Conditioner Jacks system is engineered to raise rooftop commercial air conditioning units. It comes with four manual jacks and two extensions, enabling a maximum rail spread of 10 ft. The system lifts units up to 4,000 lb, with a lift range from about 5″ to 32″; using a drop leg, the lift extends further.

Key Features:

• 4,000 lb lifting capacity
• Rail spread up to 10 ft
• Lifts ~5″ to 32″ range
• Includes 4 jacks + 2 extensions

• Capacity: 4,000 lb
• Rail spread: up to 10 ft (with extensions)
• Lift range: ~5″ to 32″
• Includes: 4 manual jacks and 2 extensions
• Weight: 155 lb (system) 
• Box dimensions and weight see operator’s manual 

• Select a flat, level section of roof rated for the anticipated load and clear the area of debris or obstacles. 
• Assemble the four jacks and the two extension rails (if needed) according to the unit width and mounting configuration. Ensure all pins and connectors are properly secured.
• Position the jacks under opposite sides of the HVAC unit, align the rails to match the unit base, then crank all jacks evenly and simultaneously to raise the unit to the required service height (up to ~32″). 
• Once the unit is at the proper height, verify stability of the base and footing, and ensure the load rating of the roof deck is not exceeded. Always maintain proper roof edge clearance and guardrail or warning line protection. 

Q: What roof surface conditions must be verified before using the AC Jack system?
A: The roof must be flat, level and rated for the total load of the HVAC unit plus jack system; never operate on slopes or weakened deck areas.

Q: What is the maximum weight capacity of the system and how should I determine the rail spread?
A: The system is rated for up to 4,000 lbs total, and the rail spread is up to 10 ft when using included extensions; ensure your unit footprint matches within these dimensions.

Q: How do I ensure safe and even raising of the HVAC unit?
A: All four jacks must be raised simultaneously using hand-cranks, ensuring the unit remains level; raise gradually and stop if uneven lift or instability occurs.

Q: What fall-protection measures are required while using this jack system on a rooftop?
A: A compliant warning-line system or guardrails must be in place at the roof edge, and operators must stay clear of unstable load zones or open edges during lift operations.
