How does the electric storage pallet truck drive brake system work?

I have heard of electric storage pallet trucks countless times. Do you know the working principle of electric storage pallet trucks?

It is a loading and unloading truck powered by DC power (battery). In terms of new materials and new processes, an important manifestation is the application of transistor controllers (SCR and MOS tubes). Its appearance has greatly improved the performance of electric pallet trucks. In general, the durability, reliability and applicability of electric pallet trucks have been significantly improved, and they can completely compete with internal combustion engine pallet trucks.

Drive and brake system of electric warehouse pallet truck

The drive system is one of the key components of electric pallet truck. There are big differences in the drive system structure of various pallet trucks. Due to the dual motor drive, the acceleration and climbing performance are good, and the traction force is large. The electronic speed control system is used to replace the original mechanical differential system, which improves the usability. Great improvement.

Universal electric pallet trucks mainly use mechanical parking brakes and hydraulic service brakes. Use the handbrake when parking and the footbrake when driving.

The use of SCR and MOS tubes makes it possible to regenerate the braking energy of the battery pallet truck. The energy regeneration process is also an electronic braking process, and the electronic braking occurs in the following three situations:

(1) When the accelerator control pedal is released.

(2) When the reverse accelerator pedal is depressed.

(3) When the first-stage hydraulic brake pedal is depressed.

For some electric pallet jacks, the traction motor turns into a generator when the brakes are applied or applied. The hydraulic brakes only really work when braking further. The advantage of this braking system is that it prolongs the working time after each charge, reduces the wear of the braking system and transmission components, and also reduces the downtime for maintenance, thereby reducing the cost of use.
