Specifications of electric height-adjustable desks

The specifications for electric height-adjustable desks primarily cover tabletop dimensions, height adjustment range, load capacity, number of motors, lifting speed, and electrical parameters. Specifications vary by desk type; common tabletop sizes include 1200×600mm, 1400×700mm, and 1600×800mm, allowing users to select the size that best fits their office space and practical needs. While larger tabletops accommodate more computers, monitors, and office supplies, they also demand higher load-bearing capacity and stability from the desk frame.

Height adjustment range is a critical specification, as it determines the desk's suitability for different users. Standard models typically offer a minimum height of 600–750mm and a maximum height of 1200–1300mm, with the exact range depending on the structure and number of segments in the lifting columns. Two-stage columns offer a relatively limited range, whereas three-stage columns generally provide a wider range of adjustment. When selecting a desk, users should consider their height to determine the appropriate tabletop levels for both sitting and standing postures, ensuring the desk can be adjusted to the optimal position.

Load capacity is another key performance indicator. Standard office-grade desks typically support 60–100kg, while models featuring dual motors and reinforced frames can handle loads exceeding 100kg. This capacity must account for the combined weight of the tabletop, monitors, computer tower, and other equipment placed on the desk; therefore, one cannot base the assessment solely on the weight of the equipment itself. When multiple monitors or heavy equipment are involved, it is advisable to allow for a load margin to ensure stability during the lifting process.

Drive system specifications include the number of motors, motor power, lifting speed, and operating noise levels. Common drive configurations include single-motor and dual-motor systems; dual-motor setups drive the lifting columns on both sides independently, achieving synchronized movement through controller coordination. Typical lifting speeds range from 20 to 40mm/s, with specific rates influenced by factors such as motor performance, load weight, and the transmission mechanism. Motor operating noise is another parameter to consider; lower noise levels result in less disruption to office or home environments.

Control system specifications typically cover features such as the control panel, display method, height memory settings, and safety protections. Basic models usually feature simple up/down buttons, whereas more advanced models offer digital height displays and multiple memory presets for quick adjustment to frequently used heights. Additionally, control systems generally include safety features such as overload protection, overheat protection, anti-collision protection, and upper/lower limit settings. If the desk encounters an obstacle or the motor experiences an abnormal load during operation, the system can halt movement immediately, thereby reducing the risk of equipment damage or personal injury.
