The main difference between a two-crank hospital bed and a single-crank hospital bed lies in the number of adjustable functions they offer:
🛏 Single Crank Hospital Bed
Adjustment Function:
- Has one crank handle, usually located at the foot or side of the bed.
- It adjusts only one section — typically the backrest — allowing the head section of the bed to be raised or lowered.
Features:
- Simple and affordable.
- Suitable for patients who only need basic positioning (e.g., sitting up for feeding or resting).
- Common in general wards or home care setups.
Example Adjustment:
- Backrest angle: 0°–75° (approx.)
🛏 Two Crank Hospital Bed
Adjustment Functions:
- Has two crank handles.
- It allows two sections of the bed to be adjusted:
- Backrest adjustment – raises or lowers the upper body.
- Knee/leg section adjustment – raises or lowers the leg section.
Features:
- Provides better comfort and patient positioning.
- Reduces pressure points and improves blood circulation.
- Ideal for hospitals or long-term care where frequent repositioning is needed.
Example Adjustments:
- Backrest angle: 0°–75°
- Knee rest angle: 0°–40°
