Two-Post vs Four-Post Hoist: Which Is Right for Your Australian Workshop?
Choosing the right hoist for your workshop is one of the most important equipment decisions you'll make. Two-post and four-post hoists each have distinct advantages — and the wrong choice can cost you in productivity, floor space, and compliance headaches. Here's how to decide.
1Two-Post Hoists: Pros and Cons
Two-post hoists are the most common type in Australian workshops. They offer excellent access to the vehicle's underside, drivetrain, and exhaust — making them ideal for mechanical work. They have a smaller footprint than four-post hoists and are generally less expensive. The trade-off is that they require precise vehicle positioning on the lift arms, and they're not suitable for wheel alignment work without additional equipment.
2Four-Post Hoists: Pros and Cons
Four-post hoists support the vehicle by its wheels, making them ideal for wheel alignment, tyre work, and storage. They're more stable and easier to load — particularly for less experienced technicians. However, they take up significantly more floor space, cost more, and provide less access to the vehicle's underside compared to a two-post hoist.
3Capacity and Load Ratings
Both hoist types are available in a range of capacities — typically 3,000 kg to 5,000 kg for standard workshop use, with heavy-duty models up to 7,000 kg for trucks and SUVs. Under AS/NZS 1418, the rated capacity must be clearly marked on the hoist and must not be exceeded. Always choose a hoist with a capacity rating above your typical maximum vehicle weight to provide a safety margin.
4Compliance Considerations
Both two-post and four-post hoists are subject to the same AS/NZS 1418 compliance requirements — annual inspections, certification, and maintenance records. However, two-post hoists have more moving parts (equaliser cables, safety locks on both columns) and typically require more frequent lubrication and adjustment. Factor this into your maintenance planning.
5Making the Decision
For most general mechanical workshops, a two-post hoist is the right choice — better access, smaller footprint, lower cost. If you do significant tyre or alignment work, a four-post hoist (or a combination of both) makes sense. For workshops with limited space, a scissor hoist may be worth considering. Whatever you choose, ensure it's installed by a licensed installer and commissioned with a compliance certificate.
The best hoist for your workshop depends on the work you do, the space you have, and the vehicles you service. Take the time to assess your needs before purchasing — and once installed, build a rigorous maintenance and compliance program around it from day one.
