When purchasing a double platform four-post parking lift, you do need to consider a number of factors to ensure that the equipment can be safely and effectively installed in your site and meet the needs of daily use. Here are a few key issues to pay attention to when purchasing:

1. Installation site size:

- Width: Double platform four-post parking lifts usually require a larger installation width, generally 5 meters or more, depending on the specific model and brand. When choosing, you need to ensure that the site width is sufficient to accommodate the necessary safety clearance between the equipment and its surroundings.

- Length: In addition to width, you also need to consider the total length of the equipment and the additional space required for vehicles to enter and exit.

- Height: The equipment requires a certain space height to ensure that the vehicle can be raised and lowered smoothly, and it is also necessary to consider whether there are obstacles above the equipment (such as ceilings, lamps, etc.) to avoid collisions during the lifting process. Generally, a clearance height of at least 4 meters or more is required.

2. Load capacity:

- Confirm whether the load capacity of the equipment meets your needs. The total load of 4 tons means that the total weight of two vehicles must not exceed this weight, and the appropriate equipment needs to be selected according to the weight of the vehicles that are parked frequently.

3. Power and electrical requirements:

- Check the power requirements of the equipment, including voltage, current and the required electrical connection type, to ensure that your power supply can meet the equipment's operating requirements.

4. Safety performance:

- Understand the equipment's safety features, such as emergency stop buttons, overload protection, limit switches, etc., to ensure that the equipment can be quickly shut down in abnormal situations to protect the safety of vehicles and personnel.

5. Maintenance and service:

- Understand the manufacturer's after-sales service policy, including equipment warranty period, maintenance cycle, repair response time, etc., to ensure that you can get timely technical support during use.

- Consider the ease of maintenance of the equipment, such as whether it is easy to clean and replace parts.

6. Cost budget:

- Before purchasing, in addition to the price of the equipment itself (such as the USD3200-USD3950 price range provided by DAXLIFTER), you also need to consider transportation, installation, commissioning and possible future maintenance costs.

7. Compliance:

- Confirm that the equipment meets local safety standards and regulatory requirements to avoid compliance issues during later use.

8. Customized requirements:

- If the site conditions are special or there are special usage requirements, you can consider customized services to better suit your needs.
