Why choose a rectangular double-section upright lifting column?

The  rectangular tube with 2 sections of positive mounting column is a two-section upright lifting column with a high-strength rectangular tube structure. It is exquisitely designed and stable in operation. It is widely used in various industrial and civil scenarios that require height adjustment or load lifting. It adopts a modular structure design, built-in double-section synchronous guide mechanism, and achieves smooth extension and retraction through electric or manual drive. It has significant advantages such as flexible installation, excellent load-bearing performance, and low operating noise.
With its compact body size of 650mm and effective lifting stroke of 490mm, the lifting column can be easily embedded in most workbenches, medical equipment, smart furniture, and industrial workstation systems, providing precise and reliable height adjustment capabilities in limited space.

Structural features
Rectangular tube structure design: The main body of this lifting column adopts a high-precision rectangular steel tube structure with a width of 80mm and a height of 50mm. It has a compact appearance and its load-bearing stability is much higher than that of the traditional round tube structure. The rectangular tube has higher bending resistance in the vertical direction, which can effectively avoid shaking or offset during lifting and ensure the smooth operation of the equipment during lifting and lifting.
Two-section telescopic structure, stroke optimization design: The lifting column adopts a two-section upright sleeve structure, and the inner and outer tubes are connected by high-precision guide grooves and sliders, which are smooth to extend and retract, with small gaps and low friction. The effective stroke of 490mm covers the height adjustment requirements of most usage scenarios. Users can flexibly control the height according to their needs to improve space utilization.
Upright installation, strong adaptability: Upright installation means that the lower end of the lifting column is fixed to the base and the upper end rises upward, which is suitable for installation in platform structures that need to "lift up" the load. Compared with the inverted structure, the upright structure is more conducive to load center of gravity control and simple installation. It is especially suitable for scenes such as office desks, medical beds, and surgical platforms.
High-precision manufacturing, reliable and durable: All metal parts are completed by CNC processing technology to ensure small assembly gaps, high wear resistance, and increase the service life of the entire column. The outer surface is anodized or powder-coated, with good anti-rust and anti-corrosion properties, and can still operate stably in humid or dusty environments.

Functional advantages
Strong bearing capacity, suitable for a variety of loads: The lifting column adopts high-strength push rod and ball screw transmission system (or screw/pulley, etc.) inside. While ensuring smooth operation, a single column can carry a large mass load, which can support up to 50-100 kg (depending on the specific customized parameters), meeting the lifting needs of heavy equipment.
Low noise, smooth operation: High-precision synchronous guide rails and buffer mechanisms are used inside, with a small friction coefficient during lifting, no jitter or abnormal noise during operation, and noise control better than 45dB, which is particularly suitable for places with high requirements for quiet environment, such as operating rooms, nursing institutions, laboratories, etc.
Easy maintenance and long service life: The internal structure design of the lifting column is simple, the running parts have low wear, and basically no frequent maintenance is required during use. The guide rail system with special lubricating materials can run self-lubricated for a long time, reducing the jamming problem caused by lack of oil or pollution. The service life can reach more than 20,000 times under normal use.
Support the use with motors, linear drives, remote controls, control boxes, etc. to achieve intelligent control functions such as one-button lifting, memory height, and limit protection. It can also be connected to the PLC or main control module and run as part of the industrial automation equipment to achieve multi-station linkage lifting.

Application scenarios
This lifting column can be widely used in the following fields due to its excellent versatility and reliability:
Smart office desk system: realize intelligent adjustment of desktop height and support sit/stand alternating office.
Medical equipment: used in medical devices such as hospital beds, nursing beds, mobile lifting tables, surgical platforms, etc. to improve medical comfort and operational convenience.
Industrial production line: embed tooling fixtures, adjust the height of workstations, improve operational efficiency and ergonomic adaptability.
Furniture intelligence: such as lifting TV stands, kitchen cabinet lifting platforms, multi-functional home systems, etc., to achieve home technology upgrades.
Laboratory and scientific research equipment: provide precise lifting control of platform height adjustment and sample delivery process.
