The XSTO ZW4250 is engineered as a durable and practical electric stair climber, offering a strong balance between load capacity, performance, and cost-effectiveness. With a rated load capacity of 250kg, it is well suited to transporting appliances, furniture, building materials, and general freight across stairs and multi-level environments.

Designed for single-operator use, the ZW4250 features a powered stair climbing system that uses a lifting foot mechanism to move step-by-step up and down stairs. Adjustable speed control allows operators to select the appropriate climbing speed depending on the load and conditions, with speeds of up to approximately 35 steps per minute for efficient operation.

A key strength of the ZW4250 is its robust construction, utilising a carbon steel frame to provide durability and strength under heavier loads. This makes it particularly well suited to demanding environments such as construction sites, warehouses, and logistics operations where equipment must withstand regular, heavy use.

The unit incorporates a telescopic handle and foldable loading plate, allowing it to be compactly stored and easily transported between job sites. Its intuitive control system uses simple touch-button operation for climbing and speed selection, ensuring ease of use with minimal training.

Powered by a 48V lithium-ion battery, the ZW4250 delivers reliable endurance, capable of climbing approximately 700–1,350 steps (around 40–85 floors) on a single charge, depending on load and operating conditions.

Positioned as a durable, mid-range upright stair climber, the ZW4250 is ideal for businesses that require higher capacity and stronger construction than lightweight models, without stepping up to premium units with advanced safety systems.

Custom Trolleys from the initial inquiry were keen to listen and understand our innovation need to resolve the safety, high labour and time consuming task of movement of high volumes of bed linen to multiple accommodation facilities while transiting up & down multiple levels of stairwells. This lead to on site discussions and reviews to understand the obstacles resulting in the timely production of trail equipment. Custom trolleys management again attended site to provide training on the equipment and after a few weeks of use attended site to engage our front-line staff to obtain there feedback which resulted in a number of design enhancements. The resulting equipment resulted in reducing safety risk and fatigue & reduced required labour hours. The outcome was introduced nationally across our Defence service contract. I do not hesitate in recommending Custom Trolleys to anyone looking for solutions to provide a safer and efficient service outcome.

We have an old stair climber that needed repairing or replacing, Custom Trolleys were great with helping us make a decision. In the end we decided to repair and add a new feature to our existing stair walker for the safety of our staff. As these repairs/upgrades were happening Custom Trolleys loaned us one so that our business could continue with normal operations, they then trained a staff member on how to use the new feature. I would highly recommend Custom Trolleys, I will definitely use them again.

Great service and product. Craig went out of this way to help us select the right powered stair walking trolley for our needs.

Throughout our purchase Craig was informative, prompt and understood our needs. The stairclimbing trolley itself seems quite robust and is easy to operate. This device isn’t cheap but I guess that’s what you pay for a quality item. Training provided was practical and well delivered. Recommended.

Great service by Custom Trollies when I lost a small part of my electric stair climber. I was out of action with the part missing. Craig found the part and express posted it to me here in Vic. Great job! Thank You!

We received amazing service from Craig on the purchase of our stair crawler, his knowledge on all products is second to none. The product is amazing and has exceeded our expectation. I can’t fault Custom Trolleys Australia in any area of sales or service. A highly professional and courteous company.

We purchased a stair climbing trolley last year, it has been a fantastic addition to our delivery service. We can do 90% of deliveries with 1 person halving our delivery costs. Highly recommended

The stair climber worked a treat and we now have our equipment in place! Thanks again for all your support getting here!
