1.2. Think like a lumberer, woodcutter. If the load is going down, Murphy is throughout, where will it go? Never be in this area.!!
That needs #1.3.

1.3. Planing is very importend. Think a while on what do you want to do. Than put all the stuff you need in an area you can reach it at any time.
After every step you have done with the load take a calm look on it: becomes the plan working?

1.4. Never put more than 3 lumber pieces top of one another (better only two pieces).

1.5. The only way: work with the weight, never against it.

1.6. Remember: someday you will forgot every damaged piece but you never forget a damaged part of the body.

1.7. Take care, god bless. 
 

2. Stuff you need
2.1. A large number of different lumber pieces (batten, blocks with different thickness, quite straight).
2.2. A crowbar.  If you handle bigger loads (more than 500 Kg or 1000 lbs you need a Bar 8' x 3'' x 4'' to got a better lever.
2.3. 3 wooden roller with quite the same diameter (bigger weight = bigger roller).
2.4. Sometimes a handbarrow is fine but not essential.
 

Some theoretics if you want
Kraft = needed power
Last = load

lesson to learn:
loads up to 500 Kg (~1000 lbs) are possible to handle "singlehanded",
loads up to 3000 Kg (~6000 lbs) are possible to handle with two persons working together.
 

Examples:

lesson to learn:
Picture 1: never do a bigger load flat to the floor (put some battens under the load).
Picture 2: put a batten between crowbar and load (like in picture 3)
Picture 3: sometimes you need some steps to got your load where you want.
but remember #1.4. and : bigger load = more steps

bigger loads transport

lessons to learn:
Picture 1: someone has forgotten the batten between crowbar and load.
Picture 2: this pic isn't correct: the middle roller must be secured with battens at      both sides.
Picture 3: the middle roller must be secured at the right side

you see: minimum are 3 rollers at the correct position and -please, secure the roller with the biggest load with a batten therewith it can't turn back. Think about your fingers!!

Roll it where you want. 

Working with a handbarrow

remember safety-rule #1.2. 

Secure the wheels from both sides!

Working with the weight

take care that your load can not press away your base. If this will be, you need to do some smaller steps. 
Remember safety rules!
