OEM two function electric hospital bed with mattress supplier: What Buyers Should Check Before Ordering

What This Product Is and Where It Fits

Consistency depends on a single‑actuator platform that drives both backrest elevation and knee‑break articulation through a shared linkage. The frame is powder‑coated 1.5 mm cold‑rolled steel, side rails are ABS, and the mattress is a 120 mm high‑density foam core with a welded‑seam PVC cover. Buyers are typically distributors or private‑label brands that need a repeatable SKU for tender‑driven hospital procurement.

Where Cheaper Alternatives Fall Short

Balance and load analysis shows that beds using a 0.8 mm steel tube and a single‑speed motor exhibit a 12 % higher deflection at the head end under a 150 kg patient load. The thinner tube also accelerates fatigue at the welded joints, leading to creak noise after 3 000 cycles. Those units typically ship without a mattress, forcing the buyer to source a separate pressure‑redistribution surface that adds cost and mismatched dimensions.

What the Design Has to Balance

Deflection under load governs the choice of actuator stroke length versus frame rigidity. A 250 mm stroke gives full backrest range but requires a larger motor housing, which adds 3 kg to the unit weight and raises freight cost. The design settles on a 200 mm stroke, 6 000 N thrust motor, and a reinforced cross‑brace that keeps head‑end deflection under 4 mm at the rated 180 kg load.

How It Is Built and What That Changes

The frame is robot‑welded on a jig that holds ±0.3 mm tolerance on the critical mounting holes. After welding, each frame passes a 500 hour salt‑spray test to verify the epoxy‑powder coat. The actuator is a sealed 24 V DC linear drive with an IP66 rating; its gear train is lubricated for 100 000 cycles. The mattress cover is high‑frequency welded, not stitched, eliminating seam failure under repeated cleaning with quaternary ammonium disinfectants.

Measured Performance in Real Use

Field data from three hospital networks show a mean time between motor replacements of 4.2 years when the bed runs 8 cycles per day. Pressure mapping on the supplied mattress records a peak interface pressure of 32 mmHg for a 80 kg supine patient, meeting the typical <35 mmHg target for low‑risk patients. The caster swivel resistance stays within 0.15 Nm after 5 000 m of corridor travel.

Customisation Options and Their Limits

Private‑label buyers can specify logo silk‑screen on the headboard, choose between grey or white powder coat, and request a 100 mm longer mattress for bariatric wards. The actuator voltage is fixed at 24 V; changing to 12 V would require a new control board and a new MOQ of 200 units. Side‑rail height can be raised 30 mm, but that adds 1.2 kg and may exceed the 180 kg load rating if the patient weight is not adjusted.

Export Packaging and Handling Protection

Each bed is shipped on a 1200 × 800 mm Euro pallet, shrink‑wrapped with 80 µm stretch film. The mattress is vacuum‑packed in a polyethylene bag to reduce volume by 30 %. Corner protectors are 3 mm corrugated cardboard; the control handset is bagged separately to avoid pressure on the membrane keys. Stacking height is limited to two units per pallet to keep the centre of gravity below 1.1 m.

Care, Storage and Service Life

Store frames upright on a dry rack; prolonged horizontal stacking can cause permanent set in the cross‑brace. Clean the mattress cover with a 0.5 % sodium hypochlorite solution, rinse, and air‑dry — avoid phenolic cleaners that degrade the PVC weld. Inspect actuator mounting bolts every 6 months; torque to 12 Nm. Expected service life is 10 years for the frame, 5 years for the motor, and 4 years for the mattress under typical 8‑cycle‑per‑day usage.
