Product Structure:

I. Core Structural Module Division (Modular Design for Easy Assembly and Maintenance)
1. Supporting Frame System
(Core Structure for Load Bearing and Stability)

Main Frame:
The lifter features an integrated lightweight aluminum-alloy frame with a net weight of 15.2 kg. The overall frame dimensions are precisely matched with the seating module. Manufactured through stamping and bending processes, the frame achieves both high strength and a lightweight profile, supporting a maximum load capacity of 200 kg.
With a total width of 560 mm, the symmetrical structural design optimizes force distribution, prevents localized stress concentration, and significantly enhances structural durability.

Bottom Support Structure:
The base of the frame is equipped with four anti-slip suction cups, evenly positioned at the four corners. The large contact area and vacuum adsorption principle improve ground adherence and stability.
Wheel mounting interfaces are reserved, supporting optional 2-inch swivel casters, enabling quick switching between “fixed” and “mobile” modes, accommodating different usage scenarios.

2. Seating Module
(Primary Carrier of Comfort and Adjustment Functions)

Seat Structure:
Designed with an ergonomic curved surface, the seat offers 450 mm width, 500 mm depth, and a 680 mm backrest height, fitting the natural contours of adult users.
The seat and backrest are connected via an adjustable linkage structure. With built-in hinges and an adjustment motor, the backrest supports 90°–120° tilt adjustment (30° tilt range), ensuring smooth and stable motion without jamming.

Seat Cushion Assembly:
Equipped with a 20 mm thick waterproof EVA cushion, the seat pad adopts a removable buckle design for easy cleaning.
The upper layer uses a waterproof and wear-resistant fabric, while the inner layer consists of high-elasticity EVA cushioning. The bottom surface features anti-slip patterns that closely fit the seat base, preventing shifting during use.

Safety Components:
A full-coverage safety belt is included as standard. The belt’s anchor points are integrated on both sides of the frame using high-strength aluminum-alloy buckles. The adjustable length accommodates users of various body sizes.
The belt is rigidly connected to the seat frame, meeting international load-bearing safety standards to prevent accidental slipping or falling.

3. Electric Adjustment System
(Core Power Unit Enabling Functional Movements)

Lifting Drive Mechanism:
The built-in electric lift motor connects to a screw-drive structure beneath the seat, enabling height adjustment from 113–488 mm (37.5 cm travel).
Operating under 24V DC, and powered by a LIB 24V/2.2Ah lithium battery, the system delivers smooth, consistent lifting speed without noticeable jolting.

Backrest Adjustment Mechanism:
Utilizing a gear-rack transmission structure, the backrest works in conjunction with the lift motor through button-based control, enabling precise tilt adjustment.
The transmission components feature anti-rust surface treatment and protective dust covers to extend service life.

Control System:
An integrated side-mounted control panel includes buttons for height adjustment and backrest reclining. The system connects to the motor and battery via streamlined wiring.
Built-in overload protection and short-circuit protection ensure compliance with 24V DC low-voltage safety standards.

4. Folding and Storage Mechanism
The frame features a foldable construction, using concealed hinges to connect the main frame with the leg-support structure.
When folded, the leg frame retracts toward the main frame, reducing the overall size to 808 × 390 × 253 mm.
A safety locking mechanism is integrated at the folding joints, which automatically locks when fully expanded, preventing accidental folding during use and ensuring structural stability.

Product Advantages:

I. Comprehensive Safety Protection System: Building a Solid Foundation for Secure Use
1. Structural Safety: Dual Assurance of Load Capacity and Stability
The lifter adopts a high-strength, lightweight aluminum alloy frame. The net frame weight is only 15.2 kg, with a total weight of 18.24 kg, achieving excellent balance between portability and durability. It supports a maximum load of 200 kg, suitable for users of various body weights (covering the vast majority of adult users).
Four anti-slip suction cups are installed at the bottom. Combined with the 560 mm overall width and stable structural design, the lifter firmly adheres to various flooring surfaces (tile, wood floor, ceramic, etc.), effectively eliminating risks of sliding or tipping during standing, sitting, or position adjustment, ensuring overall operational safety.
2. Functional Safety: Detail-Oriented Protection to Prevent Risks
A full-coverage safety belt is included as standard to securely stabilize the user—particularly suitable for individuals with limited mobility or weak balance—preventing accidental sliding or falling.
The device operates under a 24V DC safe working voltage, compliant with international low-voltage safety standards. Paired with a LIB 24V/2.2Ah lithium battery, it eliminates high-voltage electric shock hazards and ensures safe, long-term use.

Equipped with 2-inch swivel casters (optional wheels available), the lifter offers flexible indoor and outdoor mobility, suitable for living rooms, bedrooms, hospital corridors, or sidewalks. Movement is smooth and quiet.
The removable seat cushion and simplified structural design allow quick daily cleaning and deep maintenance without special tools, reducing long-term maintenance costs.

IV. Flexible Customization: Expanding Functional Boundaries
1. Optional Accessories: Tailored to Different User Needs
Supports customization with Nicolis accessories, positioning bolts, and casters. These enable flexible functional expansion:
Casters improve mobility (ideal for facility transfers or home movement)
Positioning bolts secure the seat (suitable for rehabilitation training or users who are bedridden long-term)
Accessories offer high compatibility, allowing adjustments based on the user’s physical condition and care requirements—avoiding a “one-size-fits-all” approach and meeting personalized needs across home, care institutions, and rehabilitation settings.
2. Full-Scenario Adaptability: From Home to Professional Care Environments
Suitable for daily home activities (living room, bedroom, bathroom) and also meets the concentrated care needs of nursing homes and rehabilitation hospitals. It supports short-distance outings such as hospital visits or social activities, providing “one lifter for multiple scenarios” and reducing repeated purchases.
For users with heavy care requirements, customized accessories can provide posture locking, specialized support, and other functions, catering to individuals such as post-operative patients, severely disabled users, and fully dependent elderly patients.

V. Global Compatibility: Designed for Worldwide Use
The charger supports 100–240VAC wide-range voltage (1.5A, 50/60Hz), compatible with power standards in most countries/regions without requiring an additional transformer. This facilitates cross-border sales, overseas institutional procurement, and international travel.
Standardized product specifications align with internationally recognized design norms. Components are easy to source and replace, ensuring barrier-free global use—especially suitable for international rehabilitation institutions and multinational senior care communities.
