The EMH Endtruck/Girder Connection
|
|
|
Conventional Connection
Girder mounted to top of endtruck; bolts loosely tightened, not torqued.
|
|
 |
EMH Connection
Girder attached to mounting plates on side of endtruck using a friction
connection with highly torqued bolts. |
- The EMH connection gives excellent stability in both horizontal and
vertical planes, which reduces the incidence of misalignment over time,
and gives the user a crane that moves smoothly without binding or skewing.
- High torque on the bolts produces enough friction force between endtruck
and girder mounting plates to develop the necessary holding force. The
bolts themselves never experience any shear, except for the initial
preload force put on them during assembly.
- The installation process is simplified, minimizing potential errors
that might lead to future problems.
- The EMH connection produces a straight, square and level crane that
will provide years of reliable service.
