JIMMY SERIES HYDRAULIC REBAR BENDERS — GENERAL INFORMATION

GENERAL INFORMATION

The MQ Jimmy Series Hydraulic Rebar Benders are designed
to be used as portable on-site rebar benders, capable of bending
in-place rebar to approved American Concrete Institute (ACI) radius.
Labor time and injuries are greatly reduced from manually bending
rebar. Bends of 90°, 135° or 180° can now be completed in seconds
at the correct elevation after forms are stripped away.
With seven models to choose from, the Jimmy Series rebar benders
can accommodate a wide variety of rebar angles and sizes. Please
reference Tables 1 and 2 in this manual for the rebar bender that
best fits your application.

■ Before the rebar can be straightened by the JB5090, JB7090

with each of the above models from the factory. To accomplish
this task remove the main shaft as outlined in Figure 14.
