Safety Rack
Recommendations
Spacing, limitations, and recommendations for proper use of Blackwood Safety Racks.
Tare Weight
Capacity
1 unit with 5'0" uprights: ~750 lbs
1 unit with 6'6" uprights: ~800 lbs
Spacing Recommendations
Recommended weight capacity: 60,000 pounds per base. (i.e.) a rack made up of two bases would have a recommended capacity of 120,000 pounds total, given the weight is evenly distributed.
Dense materials such as treated wood or concrete utility poles reach the weight capacity before the height capacity.
Do not stack materials above the top of the upright.
Dunnage is recommended in between layers of material.
Wood and Concrete Pole Spacing:
-
30’ - 2 units spaced 20’ apart with a 5’ overhang on the ends
-
40’ - 2 units spaced 20’ apart with a 10’ overhang on the ends
-
45’ - 3 units spaced 20’ apart with a 2.5’ overhang on the ends
-
50’ - 3 units spaced 20’ apart with a 5’ overhang on the ends
-
55’ - 3 units spaced 20’ apart with a 7.5’ overhang on the ends
-
60’ - 3 units spaced 20’ apart with a 10’ overhang on the ends
-
65’ - 4 units spaced 20’ apart with a 2.5’ overhang on the ends
-
70’ - 4 units spaced 20’ apart with a 5’ overhang on the ends
-
75’ - 4 units spaced 20’ apart with a 7.5’ overhang on the ends
-
80’ - 4 units spaced 20’ apart with a 10’ overhang on the ends
-
