1. Lifting speed:
The lifting speed of the manual stacker is 1.6 meters, which requires about 100 steps, which means that the hydraulic pressure can rise by 1.5 cm at a time. If calculated according to the hydraulic pressure for 1.5 seconds, the speed is 1cm/s, and the time required to raise 1 meter is 100 seconds. The electric stacker has a lifting speed of 10cm/s and a rise of 1 meter is 10 seconds.
This is a test when the truck is empty. If the load is operated, the manual stacker requires more human hydraulic strength and the speed will be slower! But the speed of the electric stacker is still the same. It can be seen that there is a lot of difference in work efficiency from this aspect of lifting.
2. Work continuity:
The manual stacker is operated manually, so there are not many restrictions on the continuous working time. The biggest restriction is the problem of manpower. If it is a person operating a stacker. It is quite time-consuming and laborious. It takes an average of 100 hydraulic pressures to load a cargo. If it is 30 times, it will be 3000 times. This workload is very large. Therefore, the manual stacker is not suitable for places with a large workload; it is also not suitable for places with high strength requirements, such as many places where loading and unloading in a hurry. The working efficiency of the electric stacker is more than 5 times that of the manual stacker, and the operation is easy, and the operator has little labor intensity. The standing electric stacker only needs to stand up and drive, and it is very easy to press the button to control the lifting. Therefore, the manpower is basically unlimited, and the biggest limitation is the capacity of its battery. At present, the continuous working time of ordinary all-electric stackers is about 3-6 hours, depending on stackers of different specifications and models! Generally speaking, the larger the battery capacity, the longer the battery life.
