3.1 General
The drives are designed to perform the traveling movement of the crane or trolley. The drive is not
suitable for hoisting loads. The unit is suitable for both indoor and outdoor use. Please note possible
restrictions for special environments (e.g. galvanization plants).
The main components of the drive are the motor and the gear reducer. The gear reducer is used to
reduce the motor speed and to increase the motor torque to the desired level. The gear ratio is constant
and is selected according to the motor speed and the desired traveling speed. Several sets of different
gear ratios are available, especially for two-speed motor drives.
3.2 Mounting position of the drive
The standard unit is equipped with a breather plug located at the center near the top, opposite side of the
motor. With this arrangement the drive can be mounted in any angle not exceeding 90° from the vertical
position (motor up, output shaft down). The unit can be turned in 90° increments.
The standard position of the terminal box (plug connector) on the motor is at the top. The position of the
junction box (plug) can be changed by turning the motor in 90° steps to either side.
3.3 Assembling the drive
I
Ensure that the working area is safe and the machine cannot be started accidentally when
doing the assembly work. Be sure to switch off and lock out power at the main switch to
avoid an electrical hazard.
•
Lightly grease the spline on the output shaft before assembling the unit to the wheel.
•
Align the the splines of the wheel and output shaft and push the in unit until it is seated against the
bearing housing surface.
•
Rotate the unit or the drive wheel to align the bolt holes. Note that the motor brake prevents the free
rotation of the output shaft. Manually release the brake, (see the Motor instructions) or jack the wheel
off the rail to rotate it for alignment of the mounting bolt holes.
•
Insert and hand-tighten the mounting bolts . Be sure to include the washers.
•
If the wheel is jacked up, lower it down before tightening the mounting bolts to the recommended
tightening torque. (see ‘Recommended tightening torques’ section)
F
Before tightening the mounting bolts, make sure the wheel is sitting on the rail in its normal position.
This is to ensure that a misaligned load is not directed towards the output shaft.
