Figure 40. Counterweight Installation
BW126 and BW126L Counterweight
Installation
■ The offset model is unstable without adequate
counterweight. Use counterweight box loaded with
750 lbs. of steel.
Use a suitable lifting device of sufficient capac-
ity. Use adequate personnel to handle heavy com-
ponents.
This unit may be operated with only one wing - either
right or left. With only one wing, the unit is unshielded
and unstable. When electing to operate with one wing,
you must install a counterweight box, available from
your dealer. This box has a dual purpose: it substitutes
for the shielding and for the weight of the removed
wing.
The counterweight must be installed in the following
sequence and will require at least two people. A floor
jack or a suitable lifting device will be helpful to align
the hinges when installing the hinge pin.
Refer to Figure 40.
