Hard core analysis of manual forklift drive, which one is more effortless to pull or push
Manual forklifts are important handling equipment, widely used in factory workshops and large supermarkets for cargo handling work. As we all know, manual forklifts can be pulled or pushed, which is mainly determined by different terrain environments and personal preferences. However, today, Guanhang will discuss an interesting topic with you, whether manual forklifts are easier to pull or push?
We do not consider ground factors and simply analyze which method of pulling or pushing is more labor-saving. When we push the cart, the direction of force exerted by the person points diagonally downwards, producing two force components: one force component moves forward to overcome resistance and make the cart move forward at a constant speed; The other component is vertically downward, increasing the pressure on the ground and increasing the resistance.
When pulling a car, the direction of the person's force points diagonally upwards, producing two force components: one forward to overcome resistance; The other one is vertically upward, reducing the pressure of the car on the ground and decreasing the resistance. From this, it can be seen that when pulling a car, people need to overcome less resistance, so they need to save some effort.
