why is it important to push a dolly instead of pulling it?
The reason why it is important to push a dolly instead of pulling it is because;
pushing of the dolly means that the force you apply to the heavy object would be acting in an opposite direction to the force of gravity whereas pulling it will mean the heavy object will be acting in the direction of gravity and as such the object can fall on you.
Dollies are equipment's that are used to move heavy objects around.
Now, when making use of a dolly by pushing, you have to make the dolly lean in such a way that the only part that is in contact with the ground is the tires in order for the dolly to move.
However, when you pull a dolly, you are pulling it in the direction that gravity is acting and so balancing a heavy object and then pulling it towards yourself in the direction it wants to fall will just be improper as it will fall on you in no time.
In conclusion, pushing of the dolly means that the force you apply to the heavy object would be acting in an opposite direction to the force of gravity and as such the heavy object can't fall on you like that.
