The market of equipment for loading and unloading offers consumers a wide selection of equipment that greatly simplifies human labor. One such device is a hydraulic self-propelled cart used for transporting, loading and unloading various materials. Tools of this type are simple in terms of design and very convenient to operate. They are available in various versions and can vary in capacity and purpose.
Types and description of self-propelled hydraulic trolleys
There are many different options for electric powered loading equipment. This is a trolley:
- controlled by a rotary handle by a person who is walking behind;
- managed by an operator who is in a special place or goes behind the cart, it is often used as pallet transporters, smaller in size and ideal for working in rooms with a small area;
- managed by an operator for whom a special workplace is provided (sitting or standing position).
The most productive self-propelled hydraulic trolley is equipped with a powerful battery and has a high load capacity. Due to its excellent technical and operational characteristics, the speed of the lift and the trolley's own speed are very high.
Most types of trolleys with cabs are equipped with servo steering wheels and adjustable seats.
There are traditional models, and there are also with an ergolift. The maximum lift of the forks, which are located on the trolley, is not higher than 70 cm. At this height, the load capacity is not more than 800 kg. These models are used very rarely, so the work is performed at the height of the operator’s belt.
Advantages and disadvantages
The most important plus of self-propelled hydraulic carts is the possibility of long-term operation. Their useful lives and carrying capacities are much longer than conventional carts used in warehouse loading and unloading operations.
The main characteristics of popular models:
- pitchfork rises to a height of 0.2 m;
- the possibility of lifting goods weighing from 1500 to 3200 kg;
- travel speed in the range of 6-12 km / h.
Other characteristics of self-propelled hydraulic trolleys include the following:
- The ability to perform complex maneuvers on inclined ramps, thanks to good traction.
- The physical load of the person controlling the device is reduced to almost zero, thanks to a reliable hydraulic mechanism.
- Trouble-free operation of the self-propelled cart for 5-10 years.
The disadvantages of self-propelled carts are few, but they should be taken into account:
- Work only on surfaces with a special coating.
- Wide passages are needed for free movement of the cart and operator.
Forklift trucks also reveal such important operational features - the inability to load and unload from ground level. A self-propelled hydraulic trolley is placed inside the unloaded wagon or wagon, for this it is raised to the height of the body, about 1.2 meters above the ground. In these cases, work is possible only with the use of leveling hydraulic platforms, dock levelers, and even it is necessary to use special ramps.
In other words, an aggregate weighing from five hundred to eight hundred kilograms very easily drives into the body.
The loader is a self-propelled hydraulic trolley weighing from three tons, it can not do this, because not all trucks have a sufficient maximum load capacity. Another plus is that to drive this type of transport you do not need a driver’s license, but you just need to take special courses.
General features of units
Despite the large assortment of self-propelled carts, all different, at first glance, models have many similarities. Almost each of them can lift the load with a pitchfork to a height of 70 cm. All these devices include three main nodes:
- control node;
- engine compartment (battery);
- pitchforks, which are a very important part of the construction.
For self-propelled carts, the control platform is equipped with bumpers that perform a protective function, protecting from operator injuries at turns at a speed of 10 km / h and above. There are two types of fences: folding and fixed. The first view can be folded inside the trolley or lowered. With fixed fencing to do such manipulations.
Additional features
Cart options may vary by type and model. For example, the function, which in some types of carts may be secondary, in others is mandatory. A typical example is a device that displays the percentage of charge from the trolley: for some manufacturers it is included, while for others it needs to be purchased and reinstalled. In a set, many models can have such a function as built-in charging, like a verbank on phones.
Conclusion
Self-propelled carts, like any equipment, become obsolete over time, so newer and more advanced devices appear on the market. The best modification can be considered a trolley with an AC motor. This kind of very long and well serve, economical in terms of electricity, less demanding in maintenance. Improving the engine, handle and other things can change the look of the cart: increase or make it more compact and maneuverable.
Any manufacturer makes sure that in his products there is something that others do not have, that is, adds his own signature zest. But nevertheless, the overwhelming percentage of improvements is accounted for by increasing the indicators of energy saving, productivity, safety and ergonomics.
