Hydraulic lifts are one of the essential tools in facilitating the movement of disabled, incapacitated, or less-abled individuals and play a significant role in improving their quality of life. These tools, which are used in both public spaces and homes, must be designed in a way that ensures safety standards while providing comfort and ease for the user. In this article, we will examine the dos and don'ts of designing hydraulic lifts from the perspectives of safety and user comfort.

Dos of Hydraulic Lift Design

1. Adherence to safety standards as a fundamental principle in hydraulic lift design

In the design of any hydraulic lift, adherence to international safety standards such as **EN 81** and **ISO 9386** is an undeniable necessity. These standards define the minimum safety requirements for devices to ensure the health of users. According to these standards, the maximum load capacity, permissible speed, and mechanical characteristics of the device must be designed.

One of the requirements of these standards is the existence of emergency systems, such as emergency stop buttons and automatic locks. The hydraulic lift must fully guarantee the health and safety of the user even in critical conditions. These measures not only provide peace of mind for users but also prevent the occurrence of irreparable accidents.

2. User-friendly design and easy access

The control system of the hydraulic lift should be designed in such a way that it is as simple as possible for disabled, incapacitated, or less-abled individuals to use. Controls should be large and accessible, requiring minimal pressure for activation, especially for users with muscular weakness.

Additionally, the device's displays should clearly show the necessary status information. The presence of visual and auditory alerts can also help in quick notification in case of errors or problems. This user-centered design not only ensures ease of use but also prevents stress and anxiety during operation.

3. Adequate and standard space for wheelchair placement

The hydraulic lift should be designed to provide sufficient space for various types of wheelchairs. Users need to enter the device without obstruction and move around easily. The size of the platform should be such that it allows maneuverability for all types of wheelchairs, even for larger models.

The design of the internal surfaces of the device should also be completely smooth and free of any edges or sharp obstacles. Any physical barrier inside the device can harm the user or damage the wheelchair. Therefore, using soft and shock-resistant materials inside the device greatly enhances safety and comfort.

Don'ts of Hydraulic Lift Design

1. Avoid using substandard materials in hydraulic lift design

One of the major mistakes in designing hydraulic lifts is the use of weak and low-quality materials. A device that must withstand weight and pressure cannot be made from unsuitable and weak materials. The use of corrosion-resistant and durable metals, especially in the main components of the device, is essential. Using low-quality materials only reduces the lifespan of the device and increases potential hazards.

Additionally, the mechanical and hydraulic components of the device should be regularly inspected and maintained to prevent any performance failures. Neglecting the quality of materials in these devices can lead to serious harm to the user.

2. Avoid complex and difficult designs

The design of the hydraulic lift should primarily be simple. The control system should not be complicated and should not confuse users. Any additional buttons or controls can disrupt usage. Users should be able to use the device easily and with just a few simple button presses without the need for lengthy and complex training.

The user interface design of the device should be clear, simple, and free of any ambiguity. This not only enhances user comfort but also allows for the quickest possible learning of the device.

3. Ignoring the special needs of disabled, incapacitated, or less-abled individuals in hydraulic lift design

One common error in designing lifts is overlooking the special needs of users. Each disabled, incapacitated, or less-abled individual has specific needs based on the type and severity of their disability that must be considered in the design. For example, some individuals may require larger control buttons or touch capabilities, while others may need high-resolution displays or auditory notifications.

Ignoring these special needs can lead to reduced device efficiency and user dissatisfaction. Designers must consider all these aspects to create a device that users can benefit from.

Fundamental Principles for Improving User Comfort and Safety in Hydraulic Lift Design

1. Attention to ergonomic principles in hydraulic lift design

One of the most important principles in designing hydraulic lifts is attention to ergonomics. Ergonomics means adapting the device to the physical capabilities and needs of the user. The design of the device should be such that the user can operate it with minimal effort and without additional strain.

Some ergonomic principles in device design include appropriate platform height and control button placement, the presence of soft and adjustable handles, and positioning of grips in suitable locations. Adhering to these principles ensures comfort and safety for users when using the device.

2. Use of advanced safety systems

Safety systems are one of the important components of any hydraulic lift. Installing automatic doors and safety locks can prevent accidents during device operation. Additionally, motion and weight-sensitive sensors can assure the user that the device will only start moving when the user is correctly positioned inside.

3. Adequate lighting

Another important factor in designing hydraulic lifts is their internal lighting. Sufficient lighting inside the device allows the user to easily see their path and access the controls. One of the best options is to use energy-efficient and shock-resistant LED lights. They not only have a longer lifespan but also save electricity.

Conclusion

Designing hydraulic lifts is an art that must combine safety, comfort, and simplicity. Some principles that must be adhered to include compliance with international standards, the use of durable and high-quality materials, and user-friendly design. Conversely, some aspects to avoid include unnecessary complexity in controls and neglecting the special needs of disabled, incapacitated, or less-abled individuals, which can disrupt the user experience or create hazards. By adhering to these dos and avoiding the don'ts, devices can be produced that not only ensure safety and comfort but also significantly improve the quality of life for these individuals.
