1. On the way
On the way method also known as the suspension type, it is the way of force acting on the upper track by the wheel set. Due to the complexity of the domestic balcony shape and the guardrail structure, this method is adopted in practical applications.
2. Under the way
Also known as the lower seat type, is the way of force acting on the lower track by the wheel set. In addition to push-pull frameless windows, this method is less in practical applications.
3. Up and down four ways
This method of force is theoretically achievable, but the current domestic level of technology, combined with the non-standard balcony window, is nothing more than the realization of standard CNC mechanical installation, it is difficult to achieve artificial four-point stress at the same time .
