Placing Concrete. The first thing to consider in 

 placing concrete is the runways. Build good runways 

 and support them away from the steel. 



FIG. 27. FIELD-MADE HOISTING SKIP. 



An inch board down the middle of a 2-plank wheel- 

 barrow runway is a good plan, as it keeps the plank 

 from spreading. Cleats along the edge keep the buggy 

 from running off and dropping down on the steel to 

 injure it. They also assist in dumping by blocking the 

 wheels. 



When using wheelbarrows, buy those with a high 

 front and "points" to use in dumping. 



In working on places where a misstep off the run 

 would mean a fall, injuring both the wheeler and the 

 man underneath, it is only fair to put up a strong 

 guard rail. 



Centering, unless oiled or otherwise prepared should 

 be soaked with water before running concrete. Clean
