Direct Factory steel manual hospital bed for patients Wholesale - Bulk Supply and Specification Guide

Design Constraints Behind the Specification

The frame geometry is dictated by the need to support a 250 kg static load while keeping the overall width under 1 000 mm for standard corridor clearance.

• Wall thickness 1.5 mm minimum to meet load rating
• Crank torque limited to 12 Nm for nurse operation
• Caster lock engagement force ≤ 15 N
• Powder‑coat thickness 80‑100 µm for corrosion resistance
• Mattress deck deflection < 5 mm under full load

Size, Weight and Specification Range

Buying Mistakes That Lead to Returns

A common error is selecting the light‑duty crank assembly for a ward that runs 24‑hour cycles.

When the crank rating is undersized, the handle strips after 3 000‑4 000 cycles, forcing the buyer to replace the entire drive train. The failure also shifts the bed’s centre of gravity, causing caster lock drift and increasing the risk of patient transfer incidents. Specifying the heavy‑duty crank (rated 12 Nm, 10 000‑cycle life) eliminates the early‑wear mode and aligns the service interval with the facility’s preventive‑maintenance schedule.

Segment-Specific Requirements

General Ward

• Standard 250 kg load rating sufficient
• Manual crank with 14 turns
• Two braked casters, two swivel
• Powder‑coat, 80 µm minimum

High‑Acuity / ICU

• Reinforced frame, 300 kg rating
• Heavy‑duty crank, 12 Nm, 10 000‑cycle life
• Four braked casters, central lock
• Epoxy‑primer + powder coat, 100 µm

Quality Control and Batch Consistency

Each production batch undergoes a 100 % dimensional check on the first article, followed by a statistical sample of 30 frames for wall‑thickness, crank torque, and caster lock force. Salt‑spray exposure (96 h) validates coating adhesion before shipment. Deviations beyond the stated tolerances trigger a hold and root‑cause review, preventing drift that would otherwise surface as warranty claims after installation.

Capacity, Tooling and Scheduling

Lead time is driven by four sequential constraints that cannot be overlapped without additional tooling investment.

1. Raw‑steel coil allocation – 2 weeks for certified grade
2. Stamping die changeover – 3 days per profile set
3. Powder‑coat line scheduling – 1 week for colour batch
4. Final assembly and functional test – 2 days per 200‑unit lot
