The bridle hitch can consist of two,three, or four single hitches (fig. 3-22), used
together to form a bridle hitch for hoisting an object
A sling with two legs used to lift a 1,000 pound object will have 500 pounds
of the load on each leg when the sling angle is 90 degrees. The load stress on
each leg increases as the angle decreases; and if the sling angle was 30
degrees lifting the same 1,000 pound object, the load will be 1,000 pounds on
each leg. Try to keep all sling angles greater than 45 degrees; sling angles
approaching 30 degrees are considered extremely
hazardous and must be avoided at all cost.

Scaffolding should be tied to the structure
using #9 wire or tie-in devices. The first
vertical tie
should be at the maximum height of 4 times the
narrowest base dimension. Additional ties
are not to exceed 26' vertically. Maximum
horizontal distance between ties is not to
exceed 30'.
Scaffolding, You have 32' of rise, you are using 3x5 scaffolding. Where will
the tie off points be ?

,Counterweights (Typically) are hung to counter balance the weight of the car

Note: We do not use wire smaller than #20 in travelling cables and #24 outside
travelers. Largest wires are feeders to Hoist /Pump motor
We always have 10 % spares
10% of 52 = 5.2
On a calculator Multiply the percent 10 by the number you have and ÷
by 100 10 X 52 ÷ 100 = 5.2

The correct lube must be used on chains.

Why? 535 Pg. 9
SCRs are used in DC door motor control and more commonly in Direct Drives (Replacing DC
Generators)
SCR is a three terminal device. It basically acts as an on/off switch by pulsing the gate of
the SCR with a positive voltage.
Once an SCR is turned on it remains on, till anode and cathode voltages equalize or the
anode and cathode are reversed biased or voltage is removed from the anode and
cathode. SCR's

, Notes:(Pi) π is 3.1416 and 231 Cubic inches to the
Gallon Area:
Remember to ÷ 6" ÷ 2 = 3 to get
Radius Area = π∙ r²
Area = 3.1416 x 3 x 3 = 28.27 inches or 3.146 x 9 = 28.27
Volume
Multiple are times height to solve for
Volume V = A∙H
V = 28.27 x 300 (25" feet x 12" = 300)
V = 8481 Cubic Inches
Since we already know there are 231 cubic inches to the
gallon 8481 ÷ 231 = 36.71 Gallons
