The difference between a pallet truck and an electric pallet truck

With the progress of social economy, trucks play an increasingly crucial role in our daily handling work. It is a certain kind of industrial production handling truck, which can carry out loading and unloading, stacking and short-distance transportation of commercial goods in boxes. It is widely used in seaports, bus stations, airports, freight stations, factory workshops, warehouses, and commodity circulation management. It is an indispensable motor vehicle for commercial transportation and container transportation.

In many special dangerous places, trucks have to be used. So what is the difference between a pallet truck and an electric pallet truck?

We all know that the truck is suitable for relatively special risk sites. It can strictly control its own various ignition sources when working in sites with explosive risks that have been determined to have flammable substances. Secondly, the gas detection system can be used to detect the gas concentration in the surrounding environment of the truck while properly regulating the ignition source of the truck. When the concentration reaches the corresponding ratio of the lower explosion limit, the truck will start to alarm and finally stop automatically. To achieve the purpose of safe construction.

To ensure the safe construction of the truck (truck), it is necessary to reasonably control the ignition source, remove the static electricity that may be caused during the operation of the truck, and prevent the sparks caused by the impact on the sides, tail end and fork of the truck. The temperature of the engine exhaust pipe is lowered below the specified temperature level (for example, lower than or equal to 90°C), and the exhaust system is treated. Moreover, when the engine is air intake, it is easy to inhale flammable gas or steam, causing overspeed out of control or normal combustion or accidental explosion when the flame passes through the intake system and causes backfire. When the truck encounters abnormal working conditions such as water temperature, exhaust temperature, oil temperature and surface temperature are extremely high, it can actively shut down the engine in a timely manner.

According to the above cognition, the truck needs to prevent electric leakage, prevent sparks, arcs, etc., so the truck needs special treatment. In addition, the difference between the truck and the ordinary truck is mainly in the circuit, which has high requirements on the circuit, especially the electric motor, such as DC motor, steering motor, hydraulic lifting motor, and the motor will cause sparks when it is running. There will be risks in many special places, so special protection and isolation are required. The truck uses an AC motor, because the AC motor has no sparks when it is working, so it is relatively safe. The transfer vehicle will also do special treatment at the connection between the wires for safe driving.

Therefore, in many risky places, the safety requirements are very high, such as chemical plants, oil stations, gas stations, paint, textile, military industry, pharmaceuticals, etc., it is necessary to use trucks instead of electric trucks.
