Specifying wholesale 5 function electric hospital beds with mattress and wheels Company for Wholesale and OEM Orders
Scope of Supply and Physical Form
Each unit ships as a complete system: a welded steel frame, a five‑function electric actuator set, a high‑density foam mattress with a welded‑seam vinyl cover, four lockable casters, and a handheld pendant controller. The mattress is pre‑attached to the frame to reduce on‑site assembly time, and the casters are factory‑mounted with double‑ball bearings for smooth travel across vinyl and tile.
Packaging uses a two‑piece corrugated crate that separates the frame from the mattress, protecting the powder‑coat finish and preventing foam compression during sea freight. A printed label on each crate lists the serial range, motor voltage, and mattress firmness grade so the receiving warehouse can verify the lot without opening the box.
What the Design Has to Balance
Critical Specification Rule
Motor duty cycle is limited to 30 % continuous operation; exceeding this threshold triggers thermal protection and voids the actuator warranty.
The frame must carry a 250 kg patient load while keeping the overall bed weight under 120 kg to stay within manual handling limits for two‑person teams. Actuator speed, mattress thickness, and caster diameter all compete for the same envelope, so any change in one parameter forces a recalculation of the others.
- Back‑rest angle range 0‑75° with 1° resolution
- Knee‑break articulation 0‑30°
- Height adjustment 40‑80 cm
- Trendelenburg / reverse Trendelenburg ±12°
Materials and Construction Trade-offs
Welded Frame
Continuous seam eliminates bolt‑hole stress risers, giving a 15 % higher static load rating. Powder‑coat adhesion improves because there are no crevices for moisture ingress.
Bolted Frame
Allows on‑site replacement of individual cross‑members, reducing service downtime. Slightly lower rigidity means a 5 % increase in frame deflection under full load.
| Aspect | Welded Frame | Bolted Frame |
|---|---|---|
| Structural rigidity (Nm/°) | 210 | 180 |
| Assembly time per unit (min) | 45 | 30 |
| Serviceability index (1‑10) | 4 | 8 |
| Unit cost delta (USD) | +12 | baseline |

How It Is Built and What That Changes
Frame tubes are laser‑cut to ±0.2 mm, then robotically welded in a fixtures that hold the geometry within 0.5 mm across the full 2 m length. After welding, each frame passes through a 180 °C cure oven for the epoxy‑based powder coat, delivering a 80 µm film that passes 500 h salt‑spray without blistering.
Actuators are sourced from a single qualified vendor; each motor undergoes a 10 000‑cycle run‑in at 24 V DC, 30 % duty, with torque logged at every 1 000 cycles. The mattress foam is die‑cut from a 120 kg/m³ block, then laminated to a 0.4 mm PVC‑free vinyl using a hot‑melt adhesive that retains 95 % peel strength after 30 °C/80 % RH aging for 14 days.
Where This Product Beats Standard Alternatives
Competitive three‑function beds typically lock the knee‑break and Trendelenburg motions, forcing caregivers to manually reposition patients for drainage or respiratory therapy. The five‑function platform eliminates that extra handling step, cutting average repositioning time by 22 % in a 30‑bed ward trial.
Integrated mattress removes the need for a separate procurement line, reducing SKU count and inventory carrying cost. The lockable casters meet EN 12531‑2 for brake force, a requirement that many budget beds only satisfy with aftermarket kits.

Who Uses It and Where It Matters
Public‑hospital procurement teams specify this configuration when they need a single‑source solution for acute‑care wards, step‑down units, and emergency overflow areas. Private‑label distributors value the pre‑attached mattress because it lets them ship a ready‑to‑sell kit under their own brand without a secondary assembly line.
Home‑care agencies select the lockable caster option for bedside mobility on carpet and hardwood, while field‑hospital operators rely on the 24 V DC motor that runs from standard medical‑grade battery packs during power loss.
