Figure 8-1. Internal Blocking and Bracing of a Lathe

b. Materials. Blocking of movable parts and unsupported components with fragile mounting is accomplished with

wood blocks, tie rods, yoke assemblies, steel rods, steel strapping, and wire rope.

c. Unsupported components. Due to oscillating movement during transportation the heavy suspended weights of

tables, motors, control panels, and bracketed fixtures will cause damaging stresses at mounting points.

(1) Overhanging and suspended components not easily removed, such as tables, electric motors, starters, and

pumps shall be reinforced by blocking and bracing.

(2) It may be costly and impractical to remove and separately package complex wiring systems such as electrical

control panels, disconnect switches, starters, and like items. These items frequently have fragile mounting areas and

particular care shall be exercised to assure safe movement. In addition, doors shall be secured by steel strapping.

d. Moveable parts. Operating heads, sliding tables, rams, counterbalances, and other movable parts shall be

secured by mechanical locking devices incorporated in the machine tools. These devices alone do not provide adequate

security to prevent movement in handling and transportation and, therefore, must be augmented by devices prescribed in

b above.
