Ask any laundry manager where their injuries come from and you will hear the same answer: bending into a deep tub, over and over, shift after shift.
The numbers back it up. According to Safe Work Australia’s Key Work Health and Safety Statistics Australia 2025, body stressing accounted for 50,600 serious workers’ compensation claims in 2023-24, or 34.5% of all serious claims in the country. It is the single largest injury mechanism in Australia, and the most common mechanism across every major occupation group. The median serious claim now costs $16,300 and 7.4 weeks of lost time.
For a commercial laundry, hospital, or hotel, that’s not just a number on a page. It means losing a staff member for almost two months, paying more for insurance, covering their shifts, and building a plan to bring them back to work.
A spring loaded laundry trolley is one of the few pieces of equipment that attacks this problem at its source. Instead of asking staff to reach further as a tub empties, the trolley raises the load to meet them. This guide explains how the mechanism works, how to select the right spring rating and tub size, what it costs to maintain and where it fits in your WHS obligations.
What is a Spring Loaded Laundry Trolley?
A spring loaded laundry trolley is a mobile linen tub fitted with a coil spring platform inside the base.
The springs are calibrated to a load range so when the tub is full, the weight compresses the springs and the base sits low. As staff remove linen, the load lightens, the springs extend and the base rises to bring the remaining contents back up towards the rim. The result is a consistent working height regardless of how full the tub is.
The mechanism is entirely mechanical. There is no motor, no battery, no hydraulic pump and no electrical compliance testing to schedule.
This is the difference between a spring base trolley and a powered lift. A scissor lift rise and fall trolley gives you controlled, precise height adjustment for heavy or awkward loads and is the right call in some industrial settings. A spring base gives you automatic, hands-off height correction for repetitive linen work, at a lower cost and with almost no maintenance overhead.
Why Spring Bases Matter: The WHS Case
Most facilities respond to manual handling risk with training. Train staff to bend their knees, keep the load close, avoid twisting.
Training is necessary, but under the model Work Health and Safety framework it sits near the bottom of the hierarchy of control. Administrative controls and training rely on people making the correct choice on the two-hundredth lift of the shift. Engineering controls remove the hazard from the task itself.
What it eliminates:
- Deep forward flexion to reach the bottom of an empty or half-empty tub
- Repeated trunk twisting while lifting linen out at an awkward angle
- The end-of-tub problem, where the last third of a load requires the deepest reaching at exactly the point staff are most fatigued
- The need for a second person to help empty a low tub
- Reliance on separate lifting equipment for routine linen transfer
Safe Work Australia’s Model Code of Practice for Hazardous Manual Tasks identifies awkward posture, repetition and duration as core risk factors for musculoskeletal disorders. A repetitive deep reach into a tub scores on all three. Raising the working height addresses the posture factor directly, which is why rising base trolleys are standard in OH&S-conscious Australian laundries.
If your staff are bending below mid-thigh to retrieve linen from a tub more than a few times per shift, that task meets the definition of a hazardous manual task. A spring base is one of the simplest available engineering controls.
How to Choose the Right Spring Rating
A spring base is calibrated to a weight range. Choose a spring that is too strong for your typical load and the base will sit high and barely move, which defeats the purpose. Choose a spring that is too weak and the base will bottom out under a full load and never rise.
The spring must be matched to what you actually put in the tub.
Work out your real load weight before you order: Weigh a typical full tub on a pallet scale, or estimate using the rule that wet linen weighs roughly two to three times its dry weight. A tub of dry towels and a tub of soaking wet sheets from the same department are completely different loads and may need different spring ratings.
Consider your heaviest routine load, not your average: If one shift handles wet linen and another handles folded dry stock, either specify to the heavier load or run two trolley configurations.
Ask about the spring options: Advance Trolleys supplies replacement and specification coil springs rated for different load ranges, so a trolley can be tuned to your operation rather than sold as a fixed one-size product.
Matching the spring to the task
If your tub typically holds | Load characteristic | Spring approach |
Dry folded linen, towels, garments | Light, consistent | Lighter spring rating so the base still rises on a part-empty tub |
Mixed clean and soiled linen | Moderate, variable | Mid-range rating specified to the heavier end of your normal range |
Wet or damp linen straight from wash | Heavy, water-loaded | Heavier spring rating to prevent the base bottoming out |
Mixed departments sharing one trolley | Highly variable | Specify to the heaviest routine load, or run separate configurations |
Contact the Advance Trolleys team with your load weights for a specific rating recommendation.
Choosing Your Tub Size
Bigger is not better. An oversized tub encourages staff to overfill it, which creates a heavy trolley that is hard to push and slow to empty. It also defeats the spring, because an overloaded tub sits at the bottom of its travel.
Advance Trolleys’ wet and dry tub trolley range is built around three core capacities:
Tub size selection guide
Capacity | Best suited to | Typical use |
Tight corridors, lifts, ward-level collection | Aged care, boutique hotels, ward rounds, smaller on-premise laundries | |
The general-purpose middle ground | Mid-size hotels, hospital departments, most commercial laundry floors | |
Bulk transfer and high-volume sorting | Large commercial laundries, central linen services, bulk dock-to-floor movement |
A practical test: if your staff routinely fill a tub only two-thirds full because a full one is too heavy to push, you have bought a tub that is too big. Drop a size and add a trolley.
Coil Spring Base Options: A Comparison
Not every facility needs the same base. The frame material determines how the trolley copes with moisture, chemicals and washdown, and it is the main driver of service life in wet areas.
Which coil spring base is right for you?
Base type | Corrosion resistance | Best environment | Notes |
High | General commercial laundry, hospitality, wet and humid areas | Hot-dip galvanised finish. The workhorse option and the best value for most facilities | |
Highest | Healthcare, clinical, chemical washdown, food-adjacent | Tolerates aggressive sanitising agents and frequent hot washdown. Specify where infection control audits apply | |
High | Linen-contact applications | Smooth PVC contact surface protects delicate linen and wipes down easily | |
High | Industrial, high-impact use | For sites where trolleys take a beating. No spring, maximum structural strength |
If none of the standard configurations suit your floor plan or workflow, the custom trolley service can build to your dimensions, colour coding and capacity.
Trolley Construction: What Determines Service Life
Three components decide whether a spring trolley lasts two years or ten.
The tub: High-quality rotomoulded polyethylene is lightweight, will not rust and has no seams or welds to trap moisture and bacteria. It handles wet, soiled and dry linen without degrading and it survives being knocked into door frames, which a steel tub does not always do gracefully. Smooth internal walls mean no snag points that tear linen and no crevices that harbour bacteria.
The frame: Hot-dip galvanised steel resists corrosion in exactly the conditions that destroy powder-coated frames: standing water, humidity and repeated chemical washdown. This is the single most important spec in a wet laundry environment.
The castors: Undersized castors are the most common false economy in laundry trolleys. 150mm castors roll over floor drains, thresholds and ramps that stop smaller wheels dead. They also reduce push force, which matters, because pushing and pulling a heavy trolley is itself a manual handling risk. Look for two braking castors and a smooth swivel action.
Optional push handles are worth specifying if your staff move trolleys long distances. A handle lets the worker push with the body and arms in a neutral position rather than gripping the tub rim at an awkward height.
Where Spring Loaded Trolleys are Used
Healthcare and aged care: Wards, theatres and dirty utility rooms generate constant linen turnover. Spring base trolleys reduce staff fatigue and support infection control through easy-clean polyethylene surfaces. These trolleys sit naturally alongside a facility’s broader linen trolley fleet.
Commercial and on-premise laundries: The highest-value application. Staff at sorting and folding stations perform the same reach hundreds of times per shift, which is exactly the repetition profile that produces injuries claims. This is where a spring base pays for itself fastest, and where it is worth reviewing your full commercial laundry trolley fleet rather than replacing tubs one at a time.
Hotels, motels and resorts: Housekeeping rounds involve continuous loading and unloading. A rising base means the last room on the floor is no harder to service than the first.
Food handling and industrial: The same mechanism suits produce, seafood, packaged goods, order picking and waste collection. Any repetitive task where staff reach into a deep container. Facilities running high volumes across multiple sites should also read our guide on why heavy duty laundry trolleys are essential for high-volume operations, which covers the durability trade-offs in more detail.
Setting a Maintenance Schedule
Spring trolleys are low maintenance, not no maintenance. A neglected spring base slowly stops rising, staff go back to bending and the safety benefit quietly disappears without anyone reporting a fault.
Here’s what an ideal spring trolley maintenance schedule should look like
Weekly:
- Wash the tub with mild detergent. Avoid harsh solvents on polyethylene
- Check castors spin freely and are clear of linen, string and hair
Monthly:
- Load and unload the tub and watch the base. Does it rise smoothly and return to height? If it sticks or stays down, flag it
- Check both brake castors engage properly
- Inspect the galvanised frame for chips or corrosion at weld points
Annually:
- Inspect springs for fatigue, distortion or loss of travel. Springs are a wearing part and are replaceable without discarding the trolley
- Confirm the trolley is still matched to the loads it is being used for. Departments change, and a trolley specced for dry linen three years ago may now be carrying wet
Always:
- Respect the rated load. Overloading is the fastest way to fatigue a spring and the main cause of premature failure
Common Mistakes to Avoid
- Ordering a spring rating without weighing a real load: The most common cause of a spring trolley that “does not work.”
- Buying the biggest tub available: It will be overfilled, hard to push and will bottom out the spring.
- Treating the spring as maintenance-free: It is a wearing component. Inspect it.
- Skipping the push handle to save cost: Push force is a manual handling risk in its own right.
- Specifying powder-coated frames for a wet area: Use hot-dip galvanised or stainless steel where there is standing water and chemical washdown.
- Not briefing staff: Staff who do not understand the base moves will sometimes try to hold it down or load it unevenly. A two-minute toolbox talk fixes this.
Frequently Asked Questions
Do spring loaded laundry trolleys need electricity?
No. The rising base is entirely mechanical and driven by coil springs under the load platform. There is no motor, battery or power supply, which means no electrical testing and tagging, no charging downtime and no failure risk in wet areas.
How do I choose the right spring rating for my trolley?
Match the spring to the heaviest load you routinely carry, not the average. Weigh a typical full tub before ordering, and remember that wet linen can weigh two to three times its dry weight. If the base sits high and never lowers, the spring is too strong. If it bottoms out and never rises, it is too weak. Advance Trolleys can recommend a rating if you supply your load weights.
Are spring loaded trolleys suitable for wet and washdown environments?
Yes, provided you specify the right base. Rotomoulded polyethylene tubs will not rust, and hot-dip galvanised or stainless steel spring bases are built for humid, wet and chemically cleaned areas. Stainless steel is the recommended choice for clinical and infection-control-sensitive settings.
What is the difference between a spring base trolley and a scissor lift trolley?
A spring base adjusts automatically with the weight of the load, requires no power and is designed for repetitive linen handling. A scissor lift trolley provides controlled, operator-set height adjustment and typically handles heavier or more precise industrial lifting tasks. For routine laundry work, a spring base is usually the more practical and economical choice.
How long do the coil springs last, and can they be replaced?
Springs are a wearing part, and their life depends on load weight and cycle frequency. With loads kept within the rated capacity and an annual inspection, they last for years. When they do fatigue, the springs can be replaced individually rather than replacing the entire trolley, which is a significant advantage over sealed or powered systems.
