Description
1 Guide rail
Installation of the guide rail mainly involves verticality and surface
and parallelism between two guide rails (including guide rails on the
counterweight side).
2 Guide shoe
Tightness of the guide shoes (including the one on the counterweight
loose or tight.
3 Steel rope
The drive from the motor to the car totally depends on the steel rope.
running may cause curly oscillation of the car. In addition, unbalanced
stress of multiple steel ropes may cause the car to jitter during running.
4 Brake
installed too tightly or released incompletely.
5
Balance of
the car
If the car weight is unbalanced, it will cause uneven stress of the guide
shoes that connect the car and the guide rail. As a result, the guide shoes
6 Gearbox

Resonance
caused by
the car,
guild rail
and motor
Resonance is an inherent character of a physical system, related to the
material and quality of system components. If you are sure that the
oscillation is caused by resonance, reduce the resonance by increasing
or decreasing the car weight or counterweight and adding resonance
absorbers at connections of the components (for example, place rubber
blanket under the motor).
5.6.2 Leveling Accuracy Adjustment
1 Description of leveling components
■
Leveling plate
The length of the leveling plate needs to match the leveling switch.
When the leveling switch runs across the leveling plate, each end of the leveling plate
must protrudes over the leveling switch by at least 10 mm. All leveling plates must
have the same length, with deviation smaller than 5 mm.
■
leveling switch
The leveling plate must be vertical to the leveling switch. When the car arrives, the
leveling plate must be into the leveling switch by 2/3 of its own length.
■
Optoelectronic switch
The NO-type photoelectric switches are recommended to improve signal sensing
stability.
