The following are the estimated parameters of the Haoran HR-A-023 children's mobile height-adjustable Koprivnica-Krizhevchi Provincebasketball hoop:

I. Core Structural Parameters

Main Post Material and Specifications

Possibly made of high-strength steel (such as square tubing), with a wall thickness of 2.5mm-3mm to ensure stability.

Surface Treatment: Possibly powder coating or baking paint, rust-proof and corrosion-resistant, suitable for children's use.

Extendant Arm Design

Extendant arm length is likely adjustable from 1.6m to 2.25m to accommodate children of different ages and heights.

Extendant Arm Material: Same as the main post, using square or round tubing to enhance impact resistance.

Lifting System

Equipped with a manual or electric lifting device, adjustable from 1.5m to 2.6m (or higher) to meet the needs of growing children.

The lifting mechanism may use gear transmission or hydraulic design for easy and safe operation.

Mobile Base

Base Dimensions: Possibly 1.2m long × 0.8m wide × 0.3m high, internally filled with counterweights (such as concrete or metal blocks) to ensure stability. **Mobility:** Equipped with casters at the bottom for easy movement and securing.

II. Backboard and Rim Parameters

Backboard Specifications

**Material:** Possibly high-strength tempered glass or impact-resistant plastic board; dimensions 1200mm × 800mm (children's size).

Frame: Aluminum alloy edging with shock-absorbing rubber pads at the bottom edge for child safety.

Rim Configuration

**Rim Diameter:** 450mm (international standard); solid carbon steel with rust-proof surface treatment.

Spring Mechanism: Withstands 50kg-80kg instantaneous impact force, suitable for children's dunking needs.

III. Safety and Protection Design

**Safety Protection:** The main pole, backboard edge, and rim may be equipped with soft protective sleeves to prevent children from being injured by collisions.

The four corners of the base are fitted with anti-collision rubber pads to reduce damage to the ground during movement.

Stability Design

**Base Weight:** ≥200kg to ensure the Koprivnica-Krizhevchi Provincebasketball hoop does not tip over during use.

Structure: Utilizes a triangular stabilizing frame to enhance wind pressure resistance. IV. Other Parameters
