Four-Post Lifts

The main difference between four-post and two-post lifts is their structure and application. Four-post lifts have four vertical columns supporting a platform that allows for storage of a vehicle. They're more stable, require no special mounting (typically don't need to be bolted to the floor), and are ideal for long-term storage and general service work.

Two-post lifts use two columns with arms that connect with the vehicle's frame or designated lift points. They provide better undercar access since they don’t have runways, but they have to be properly anchored to the floor and require more technical knowledge to position the vehicle correctly. Four-post lifts are generally considered more user-friendly and versatile, while two-post lifts are preferred for extensive undercarriage work.

Four-post lift weight capacities typically range from 7,000 lbs. for home garage models to 40,000 lbs. for heavy-duty commercial applications.

• Most standard four-post lifts for passenger vehicles and light trucks have capacities between 8,000-9,000 lbs.
• Mid-range models often support 12,000-15,000 lbs. for SUVs and larger trucks.
• Heavy-duty commercial lifts can handle 18,000-40,000 lbs. for commercial vehicles and equipment.

Always check the manufacturer's specifications to choose a lift with a capacity that fits your heaviest vehicle.

The ceiling height required for a four-post lift depends on the maximum rise height of the lift and the height of the vehicle. For standard four-post lifts with around 70"-75" of rise, you need a minimum ceiling height of 11-12 feet to work comfortably underneath a raised vehicle. Low-rise four-post lifts designed for storage may only require 9-10 foot ceilings.

For taller vehicles like SUVs or vans, add the vehicle height, the lift's raised height, and at least 6 inches of clearance on top of that number.

Four-post car lifts offer a range of benefits that make them ideal for both home garages and professional shops, including:

• Support at all four corners ensures safety while working underneath the vehicle
• Easy installation, with most models requiring no floor anchoring, making them portable if necessary
• Drive-on design that eliminates the need to precisely position lift arms, reducing the risk of vehicle damage
• Versatile enough for both maintenance and long-term storage, effectively doubling garage space
• Can be equipped with accessories like rolling jacks for wheel-free service without sacrificing stability
• Open space between runways offers excellent access to exhaust systems and drivetrain components
• Typically supports higher weight capacities than two-post models, accommodating heavier vehicles safely

Most four-post lifts don't require bolting to the floor for standard operation (which is one of their key benefits). However, always check the manufacturer's recommendations since some situations may require anchoring, like:

• Using the lift in areas prone to seismic activity
• Installing the lift on an uneven surface
• Manufacturer-specific warranty requirements
• Certain commercial applications with specific safety regulations

Even when anchoring isn't required, ensure the lift is placed on a level, properly reinforced concrete surface that meets the manufacturer's minimum specifications for thickness and PSI rating. Generally, the required concrete thickness for a car lift depends on the lift type and capacity, but most two-post and four-post lifts require a minimum concrete slab thickness of 4 inches. The concrete should be sound, reinforced concrete (usually at least 3000 PSI compressive strength).

For smaller shops with limited space, consider compact BendPak models like the HD-7P or HD-9ST. These lifts offer excellent functionality while minimizing the footprint required.

The BendPak HD-7P has a 7,000 lbs. capacity with a narrower width and shorter length than standard models, which makes it ideal for tight spaces while still accommodating most passenger vehicles. For a slightly larger capacity in a compact design, the BendPak HD-9ST offers a 9,000 lbs. capacity with space-saving dimensions. Both models feature BendPak's renowned quality construction and safety features.

Other space-conscious options include the Dannmar D-4P, which balances compact dimensions with professional-grade performance.

Entry-level four-post lifts for home garages typically start in the lower price range, while commercial-grade models with higher capacities and additional features command premium prices. Factors affecting pricing include:

• Weight capacity
• Platform length
• Alignment capability
• Rolling jacks or other specialty accessories
• Brand reputation
• Warranty coverage
• Installation costs

The best four-post car lift highly depends on your specific needs, but BendPak consistently stands out as an industry leader. For general service and storage in home garages, the BendPak HD-9 series offers exceptional quality, reliability, and versatility with its 9,000 lbs. capacity and numerous configuration options. For commercial applications, BendPak's HDS-14 series provides increased capacity and durability for daily professional use.

BendPak's lifts feature automatic safety locks, redundant hydraulic systems, and high-quality materials that ensure years of trouble-free operation. Their powder-coated finish resists corrosion in demanding shop environments, and their warranty coverage demonstrates confidence in their products.
