The ceiling mounted basketball hoop adopts an electric winch to fold and unfod,, and provides a safety protection device with automatic locking belt. Fully automatic control, it can complete the unfolding and folding action once around  one minute. 

1. The two-phase 

2. KW 9-pole electric power machine is used to drive the large ratio worm reducer to finish  the automatic lifting or expansion of the electric drive system; 

3. The unique and specially designed automatic safety locking belt device ensures the absolute safety of the hoop  system during use. The automatic safety lock belt can automatically lock the basketball stand in case of accident. 

4. Performance parameters of electric winch: weight: 30.84kg, overall dimension: length x width x height =988mmx450mx267mm, working voltage: 220V, rated current: 4a, frequency: 50Hz, power: intermittent working system  10min, maximum load: 453.6kg, stroke: 11m, maximum running speed: 2.7432m/ min (reducer output speed 8r/min) 

5. Parameters of automatic safety belt locking device: weight: 8.62kg, maximum breaking force: 23.43kn, stroke: 15m, Maximum running speed: 25.6m/min

6. Main beam: Q235 high-quality square tube with diameter of 120*120 and wall thickness of 3, 100*48*5mm thick 10 channel steel, fully welded into a triangular main bearing frame. Firm structure and reliable performance. 

7. Connecting piece: a 16mm diameter U-shaped clamp and the flange with a wall thickness of 8mm are used to connect the balance bearing rod. The main beam and the balance bearing rod are connected by M24 articulated bolts, and are connected by a pin shaft with a lock pin, which is easy to maintain and replace worn parts. Reasonable structure and reliable strength. 

8. Backboard: Official Size: 1800mm*1050mm*12mm thick high-strength safety glass basketball board, 2mm thick high-strength aluminum alloy basketball board is used outside. The whole backboard has beautiful appearance, simple and firm . 

9. Three spring game basket rings : abide  by the first-class competition standard 

    The ring  is made of  20mm round steel and has a reinforcing plate structure inside. Strong strength and strong bearing capacity. 

10. Surface treatment: after primary treatment such as acid pickling and phosphating, the surface of all steel parts is finally treated by electrostatic epoxy powder spraying on the automatic spraying line. The coating thickness is 70-80um, and the hardness is 3h+. After gb1771-9136 hour salt spray test, the coating film has no change, and the corrosion on one side of the cross is less than 2mm. It has the advantages of acid and alkali resistance, (jr-188) damp heat resistance, aging resistance, beautiful appearance, etc., and the product coating formula does not contain toxic elements, Avoid damaging the health of users.
