1. Make sure it is your own equipment.
2. Make sure you don't have to many of the same items on you.
3. Make sure its not in the wather when you try to pick it up.
4. Make sure you are in range of the equipment.
5. Train your mussels and you might be strong enough one day.
One thing is to make sure it is in fact your road equipment. It's a common mistake when several officer respond to the same road incident, to mistake each other's road equipment. So make sure it is yours.
Another thing would be to try moving closer to the item you are attempting to pickup, I mean really get on top of that thing.
