What the Design Has to Balance
Load capacity, articulation range, and motor endurance compete for the same frame envelope.
A 250 kg safe‑working load forces a 2 mm cold‑rolled steel chassis with 80 µm powder coat; the same chassis must accommodate a 300 mm actuator stroke for backrest (0‑70°) and knee break (0‑30°) while keeping the overall width under 1000 mm for standard doorways. Motor life is rated at 20 000 cycles at full load, noise stays below 45 dB(A), and the control electronics meet IPX4 splash protection. Every millimetre of frame thickness adds weight, which raises freight cost and reduces the number of units per container.
Specification Range and Customisation Limits
| Parameter | Standard Range | Custom Limit |
|---|---|---|
| Safe‑working load | 250 kg | 300 kg (requires reinforced casters) |
| Backrest angle | 0‑70° | 0‑80° (actuator stroke increase) |
| Knee break angle | 0‑30° | 0‑35° (requires longer link) |
| Motor cycle rating | 20 000 cycles | 30 000 cycles (premium motor) |
| Noise level | ≤45 dB(A) | ≤40 dB(A) (silent‑run option) |
| IP rating | IPX4 | IPX5 (sealed control box) |
| Caster diameter | 125 mm with brake | 150 mm (bariatric) |
| Battery backup | 2 h at full articulation | 4 h (larger pack) |
The table above defines the baseline that every private‑label order starts from; any deviation beyond the “Custom Limit” column triggers a new tooling quote and a minimum order quantity review.
Customisation Options and Their Limits
Colour, branding plate, and siderail style are the only free‑form variables. Frame geometry, actuator mounting points, and motor housing are locked to the validated design; changing them would require a full re‑qualification cycle and a new safety file.
Standard Motor Package
20 000 cycles, 45 dB, IPX4, 2 h battery. Lowest unit cost, fits 95 % of ward specs.
Premium Motor Package
30 000 cycles, 40 dB, IPX5, 4 h battery. Adds ~12 % to unit price; justified for high‑turnover bariatric wards.
Mattress platform can be supplied as a flat deck or with integrated pressure‑mapping pockets; the latter adds 3 kg per bed and a 5 % cost uplift.
Usage Scenarios and Buyer Segments
Acute‑Care Hospital Ward
Frequent repositioning, 24/7 operation, strict infection‑control cleaning. Demands IPX5 control box and silent‑run motor.
Long‑Term Care Facility
Lower articulation frequency, emphasis on battery backup for power‑outage resilience. Standard motor package sufficient.
Home‑Care / Private‑Label Retail
Aesthetic colour match, branded siderail, compact packaging for parcel shipment. MOQ can be as low as 20 units with custom colour.
Bariatric Specialty Unit
300 kg load, 150 mm casters, reinforced frame. Requires premium motor and extended warranty negotiation.
Procurement officers typically lock the configuration to one of the four profiles above; mixing profiles in a single container adds handling complexity and raises the per‑unit inspection cost.
How Consistency Is Held Across Batches
First‑article inspection validates every critical dimension against the master drawing.
Statistical process control tracks frame weld pitch, powder‑coat thickness, and actuator stroke on a per‑shift basis; any drift beyond ±0.15 mm on weld pitch or ±5 µm on coating triggers a hold. Motor endurance is verified by a 5 000‑cycle accelerated test on a 10 % sample from each production lot. Caster brake torque is measured at 12 Nm minimum. All results are logged to a batch‑traceability database linked to the serial number plate on each bed.
| Test | Method | Acceptance |
|---|---|---|
| Frame dimensional | CMM scan 10 points | ±0.15 mm |
| Coating thickness | Magnetic gauge, 5 spots | 80 µm ± 5 µm |
| Motor cycle life | 5 000 cycles accelerated | No failure, noise ≤45 dB |
| Caster brake torque | Torque wrench, 3 samples | ≥12 Nm |
| IPX4 splash | Spray 10 min, 10 L/min | No water ingress |
Ordering, Tooling and Lead-Time Questions
- What is the minimum order quantity for a custom colour? 20 units; tooling for the powder‑coat mask adds 2 weeks.
- How long from purchase order to first shipment? 6‑8 weeks for standard configuration; 9‑11 weeks if premium motor or bariatric casters are specified.
- Can we supply our own control‑panel overlay artwork? Yes, vector files (AI/EPS) at 300 dpi; approval proof sent within 3 business days.
- What warranty terms are offered? 24 months on frame, 12 months on motor and electronics; extended to 36 months on frame for orders ≥100 units.
- How are beds packaged for container loading? Each bed on a steel pallet, shrink‑wrapped, four per 40‑ft container; optional corner protectors for sea freight.
- Is there a sample‑approval step before mass production? Mandatory; a single pre‑production unit ships for functional sign‑off, 10‑day review window.
