AKD- 8, Using J Lifting bar
Figure 35
Use FRONT Rectangular
cut to insert J - lifting bar
Note 1: Make sure the J hook of the lifting bar is secured in the front window on both side
sheets of the breaker as shown in fig 35. This will ensure the breaker is better
balanced when lifted.
Note 2: The size of the slot at the top of the lifting bar is 0.7" wide and 1" high. Hooks used
in the hoist should be suitable to engage with this slot size. After loading on rails of
fully withdrawn position remove the eye bolts or lifting means.
Note 3: Use of Lifting bar or spreader bar allows to reach the top most switchgear
compartment easily, So it is the recommended method.
Note 4: As an alternate to above lifting process, eye bolts, chain attached to eye bolts
through S hook, and connector can be used to lift the AKR Retrofill Breaker. Examples
of an eye bolt and connector are shown in fig's 36 and 37. Insert M10 eyebolts of
rating minimum 250lbs in the eye bolt weld nuts as shown in Figures 38. Use four
eye bolts, chain and suitable "S" hooks or chain connectors to safely lift the breaker
onto the rails. "S" hooks with a locking feature as shown in Figure 8D are preferred
to basic "S" hook s. Each chain should be rated minimum 500lbs. Mount a connector
to join both chains in the center. Connector should be rated minimum 1000lbs. The
connector is then attached to a hoist hook as shown in Fig 38 to lift the breaker.
Note: Eye bolts, chain & connectors are not supplied. If used, remove before installing
breaker into the compartment.
