With loads over 150 kg, transport on stairs with a step-by-step system can, in our opinion, be inconvenient as well as dangerous. This is why we do not recommend it.
The reason lies completely in the fact that, with all stair climbing trolleys, it is the operator's task to keep the load balanced when going to the next step. In our opinion, locking systems on the wheels and similar are only attempts to reduce a dangerous passage, but they do not solve it completely. With certain weights you must protect your back; it is therefore impossible to keep the load balanced.
The point is that as the transported weight increases, the effort employed by the operator also increases in direct proportion, because there is a certain interaction between the operator and the stair climbing trolley itself.
It is therefore necessary to limit this interaction as much as possible to ensure the highest level of comfort and safety.
This is only possible with the Skipper tracked model.
SKIPPER is a latest generation electric stair climbing trolley suitable for relatively heavy transport and is fitted with a remote control that allows the operator in some circumstances to control it without interacting with the transported load.
With Skipper the gradient of the stairs is no longer a problem, because you can change the tilt at which you want the load to travel at any time.
You can also cross any type of flooring thanks to the special patented mix of the rubber coated tracks.
Even the height of the steps is irrelevant as Skipper always works on their ridges with 6 support points during the stair travel stage.
Here are SKIPPER'S ADVANTAGES
Safety: The weight is always transferred to the ground or the stairs; the operator can work in absolute safety in the most critical conditions.
Convenience: The interaction between the load and the operator is reduced to the minimum; therefore the latter no longer has to support the transported weight.
Versatility: By always working on the ridge of the steps, Skipper manages to overcome even very tall steps in comparison with a step-by-step system; hence it has more possibilities for use.
Overcoming steep stairs: Thanks to the possibility of changing the transported load's tilt at any time, you can succeed in working in even exceptional conditions.
Motorized track: With the special ZONZINI branded tracks you can travel effortlessly up and down slopes, on dirt tracks and on uncertain flooring.
Reduced turning space: It turns in the same space as a manual trolley, even on spiral stairs.

Here are the Accessories for Skipper
Accessories included in the price
Automatic battery charger: It uncouples automatically when it reads the battery charge; there is no danger of overcharging.
Securing strap: It uses technology with ratchet tightener; it therefore always ensures optimum locking.
Standard battery box: Intelligent batteries without memory effect. They can be recharged even if not completely flat.
Optional accessories
Additional securing strap: For those who have loads with particular shapes.
In-vehicle battery charger: To charge the battery box even when travelling
Additional battery box: To increase autonomy of work. If you exchange the original battery box with the additional one, you get practically unlimited autonomy.
Simple base with revolving wheels: This is particularly suited for the transport of fairly heavy loads that are sometimes bulky. You could say that this is the correct accessory for those on a limited budget who want an effective tool suited to every type of load.
Technical specifications:
width: 30 cm
depth:62 cm
ground clearance: 12,5 cm
Base with anti-tip system: The base with anti-tip system is particularly suited to the transport of heavy bulky loads. This system aids the operator in two fundamental circumstances: At the beginning of the ramp it allows the load to be automatically tilted onto it, the operator therefore expends no effort to carry out this operation. Secondly, there is absolutely safety on the last step because it removes any possibility of tipping the load if its balancing is lost.
Technical specifications:
width: 30 cm
depth: 62 cm
ground clearance: 12,5 cm
Base with anti-tip and lift system: The base with anti-tip and lift system is particularly suited to the transport of heavy bulky loads on very tight stairs. This system helps the operator both to tilt the load on the stairs at the beginning of the ramp and to facilitate the manoeuvre on the last step preventing the load from being tipped. Its special characteristic, however, is to be able to lift the whole load 42 cm, thus managing to overcome the first and sometimes the second step of the next ramp to actually increase the dimensions of the landing and also turn in very tight spaces.
Technical specifications:
width: 40 cm
depth: 56 cm
ground clearance: 12,5 cm
Aluminium ramp: The aluminium ramp is a handy solution for those that want to load and unload any type of good directly from the van. It should be remembered that Skipper, from nothing, is capable of going up and down from the van even without a ramp. Just lean the tracks on the body and hold down the up/down button. In fact the vehicle's body is only seen as a higher than average step.
Technical specifications:
width: 65 cm
depth: 200 cm
depth: 7,5 cm
Wheeled base: The wheeled base is the most suitable tool for those who want to confront any type of flooring without problems. Thanks to the two pneumatic wheels and the two revolving wheels, it can handle any type of load with the utmost ease on any type of ground. The weight is always transferred to the ground without weighing on the operator's arms. This accessory is of great help to all those who, not being able to find parking immediately near the place of delivery, have to confront pavements, humps, rough ground or gravel to reach the place of delivery.
Accessory for doors and windows: It is possible to position doors and windows tilted against the loading platform so as to reduce the bulk.
