The hydraulic forklift truck received its alternative name from the Finnish company of the same name Rocla. The rokla cart is characterized by the simplicity of design, the operation of the device does not require professional skills. Another advantage of the device is the ability to move loads manually. The exception is electric Pallet Truck, operating from a battery-powered engine. The remaining hydraulic bogies are driven without electrical sources of energy and fuel. Enough operator effort.
Design and principle of operation
The fork structure of the pallet truck functional unit is oriented mainly under the movement of pallets with goods fixed with a film. Structurally, a hand pallet truck consists of five structural components:
- forked base;
- basic and roller wheels;
- shipping handle;
- control lever;
- hydraulic unit.
The last element determines the principle of operation of the entire unit. Functionally, it is similar to a jack. Similarly to this mechanism, in pallet truck, the hydraulic system is represented by two containers filled with oil. The spool of the smaller tank is attached to the handle. In larger it is connected to the pitchfork.
The downward movement of the lever exerts pressure on the corresponding spool, displacing it in a similar direction. The part, dropping, transfers the force to the spool connected to the forks, as a result of which both elements move up. Repeated pressing on the handle allows you to raise the forks of the Pallet Truck cart to the required height.
The purpose of the hydraulic carts
Hand pallet truck is an excellent means of moving goods on the paved territory of a private home.
At the industrial level, pallet truck hydraulic is in demand:
- inside warehouse complexes;
- large shopping complexes – super- and hypermarkets;
- construction sites;
- agricultural complexes, small farms;
- industrial facilities – workshops, factories and factories.
Pallet truck can be used wherever maneuverability is required and hard surface is present. Since the hydraulic forklift truck does not need fuel, its operation reduces a part of the enterprise expenses.
Pallet truck – varieties of the device
According to the principle of movement, lifting trolleys are divided into two categories – manual and electric. The first group has its own classification, which includes the following types of hydraulic devices:
- low profile;
- equipped with weights;
- increased carrying capacity;
- with various sizes – short, long or wide pitchforks;
The latter variety combines maneuverable carts, devices for transporting rolls and for working in special conditions. To increase the maneuverability of the structure, the pallet truck is equipped with transverse roller wheels. Transportation of rolls is carried out on forks of a triangular section.
Under operation in an aggressive environment, special attention is paid to the material of the hydraulic carts. This pallet truck has steel wheels and a stainless steel frame.
To choose and buy best pallet truck correctly, you need to pay attention to the specifications of the device. Among the selection criteria, the following characteristics of the hydraulic trolley are important:
- Carrying capacity. In manual standard models, indicators are up to 2 tons.
- Ultimate fork lift heights. Low profile Pallet Truck is characterized by a minimum size of 35 mm. A standard device has a lower limit of 70 – 80 mm, and an upper limit of 200 mm. An exception is scissor rockl, lifting loads to a height of 800 mm.
- The length and width between the forks.
- Type of wheels – single, double or steered rollers.
For maneuvering applications, it is advantageous to purchase a short-forked pallet truck equipped with transverse wheels. To increase the load capacity allow electric models of trolleys.
Electro Pallet Truck
The sale of self-propelled hydraulic trolleys is focused on increasing the carrying capacity. Pallet Truck on an electric motor is characterized by the following key parameters:
- carrying capacity 1.5 – 3 t;
- speed of movement is up to 13 km / h;
- lifting height of cargo over 120 mm.
In industrial warehouses, the lifting height of the hydraulic trolleys is not enough, therefore, they are used together with electric forklifts or diesel forklifts.
