Retractable Bleachers and Seats SQ-9002 is an electric retractable seating system designed for sports venues, indoor halls, and multi-purpose facilities. The bleacher system can expand and retract freely through an electric drive mechanism, helping venues adjust seating areas according to different usage requirements.
The structure can be designed according to the venue layout and actual site conditions. Configuration, arrangement, and seat color can be selected based on project requirements. Each row and column is marked with clear identification for convenient audience seating management.
The retractable bleacher system provides flexible seating management for facilities that require space conversion. When not in use, the seating structure can be retracted to release floor space for other activities.
The system combines retractable movement, spectator seating, and structural support components into one integrated grandstand solution.

The SQ-9002 retractable bleacher system uses an electric drive structure for free expansion and retraction. The motorized movement design allows the seating area to be adjusted according to venue requirements.
The retractable bleachers can be designed based on the sports venue layout and actual installation conditions.
Project configuration can include:
The seats use hollow blow molding technology with polyethylene as the main raw material.
The seat installation center distance is 480mm, providing an organized seating arrangement for spectators.
The main support structure uses a vertical frame design with rectangular steel tubes.
The structure includes:
These components work together to form a stable supporting framework.
The retractable system uses upper and lower guide structures.
The upper guide rail is made from 4.5mm steel plate with a one-time bending process. The guide system includes double bearing pulleys and adjustable steel top wheels.
The lower guide system uses double bearing polyurethane casters. The caster structure includes an internal double ball bearing system and an external high-strength wear-resistant polyurethane layer.
The polyurethane caster system is designed to support smooth movement while reducing floor wear during retractable operation.
The drive wheel system uses independent four-wheel drive. The drive wheels feature an internal cast iron structure with an external rubber covering layer.
The platform uses 18mm plywood with a high wear-resistant waterproof surface layer.
The decking provides a practical surface solution for retractable grandstand applications.
The safety railing is welded from steel tubes with an effective height of 1100mm.
Additional safety components include:
The railing can be removed and installed without affecting the expansion and retraction operation.
