Choose by Service Access and Vehicle Support
Two-post lifts support a vehicle at approved lifting points. Four-post lifts generally support the tires on runways. The appropriate choice depends on the exact equipment, vehicle, work and site.
Two-Post and Four-Post Comparison
| Consideration | Two-Post Lift | Four-Post Lift |
|---|---|---|
| Typical work | Wheel-free mechanical service using approved lifting points | Drive-on service and permitted storage; alignment requires a suitable model |
| Vehicle positioning | Check arm placement, adapters, lifting points and load distribution | Check tire position, runway spacing, wheelbase and load distribution |
| Wheel access | Wheels are free in a correctly supported setup | Wheel-free work requires compatible, properly rated accessories |
| Space | Measure columns, arms, vehicle and service clearance | Measure columns, runways, ramps, vehicle and service clearance |
| Installation | Follow exact concrete, anchor and layout requirements | Follow exact concrete, anchor and layout requirements; do not assume freestanding use |
| Cost | Compare the selected configuration and complete installation | Compare the selected configuration, required accessories and complete installation |
When to Compare Two-Post Models
Consider a two-post lift for frequent wheel, brake, suspension or other mechanical work when the vehicle's support points and geometry fit the model. Check the individual arm limits and planned service procedure as well as the total capacity. Underbody access varies with the vehicle and arm arrangement.
When to Compare Four-Post Models
Consider drive-on convenience, service access and storage applications approved for the model. Drive-on loading still requires correct vehicle positioning. Verify runway and vehicle dimensions, access ramps, all installation requirements and the intended raised positions.
A caster kit does not cancel anchoring requirements or permit moving a loaded lift unless the manufacturer expressly allows that use. Check the approved movement conditions for the specific model and kit.
Rolling Jacks and Alignment
Confirm jack-rail dimensions, supported accessories, capacity, support points and approved vehicle setup before adding a rolling jack. Alignment work requires a suitable alignment lift and the required equipment. A rolling jack alone does not make a parking lift an alignment rack.
Safety and Operator Training
Post count alone does not establish that one lift is safer, easier for an inexperienced operator, or suitable for heavy component removal. Both require correct installation, training, positioning, inspection and use of the manufacturer's safety systems.
Check the Vehicle and Site
Verify actual loaded vehicle weight, weight distribution, approved lifting points, dimensions, and the manufacturer's total and individual support limits. A vehicle category or a fixed percentage added to its weight does not establish compatibility.
Measure the exact lift footprint, vehicle access, raised vehicle height, working space, doors, tracks, openers and other obstructions. Have concrete condition, thickness, strength, anchoring and required clearances assessed for the chosen model before preparing the site. There is no universal ceiling height or slab specification for every lift.
Utilities, Installation and Budget
Confirm the supplied voltage, phase, frequency, circuit, grounding and any required air supply. Configuration prices may differ. KT-4H120PX and KT-4H150 are supplied with 220V electrical power units and require an external compressed-air supply for pneumatic safety-lock release. Electrical power and compressed air are separate utility requirements; confirm the supplied lift and rolling jack's pressure, flow, fittings and installation requirements before ordering.
Obtain a model-specific installation quote and follow the applicable assembly, commissioning, inspection and maintenance instructions. Professional installation does not automatically establish warranty coverage or certification; review the actual documents and terms.
Compare equipment, freight, unloading, site preparation, utilities, accessories, installation and ongoing service costs. Use current prices and quotes. Estimate payback from your own workload and costs rather than assuming a fixed return period.
Stock, Freight and Supplier Pickup
Product prices and freight are shown separately. Confirm delivery access, packed dimensions, shipment weight and unloading needs; liftgate service is available only where offered for the product and address.
Contact ALLIZOE before ordering or paying for supplier warehouse pickup to confirm actual stock and the warehouse. Confirmed pickup is free with no freight or handling fee, by appointment only; no same-day pickup is available. Wait for written readiness confirmation and the supplier release form before traveling. See our pickup guide and delivery guide.
