Hospital Bed 2 Cranks vs 3 Cranks: Henyuan Medical Complete Guide

Choosing the right hospital bed is critical for patient comfort, safety, and caregiver convenience. Among manual hospital beds, one common decision is whether to select a 2-crank or 3-crank model. In this comprehensive guide, we will explore Henyuan Medical 2-crank and 3-crank hospital beds, their uses, technical specifications, benefits, and provide practical selection advice.

Understanding the Difference: 2 Cranks vs 3 Cranks

The main difference is that a 3-crank bed adds overall height adjustment, while a 2-crank bed only adjusts the backrest and leg rest. A 2-crank bed allows for adjustments to the head and leg sections, providing patient comfort and support. A 3-crank bed includes this plus a third crank to raise and lower the entire bed frame, which is useful for caregivers who need to adjust the bed’s height for patient care or transfers.

2-Crank Hospital Bed

Adjustments: Backrest and leg/knee rest
Function: The first crank typically adjusts the head or back section, while the second adjusts the leg section.
Best for: Basic patient positioning and comfort without the need for height adjustment.

3-Crank Hospital Bed

Adjustments: Backrest, leg/knee rest, and overall height
Function: The first two cranks adjust the back and leg rests, similar to a 2-crank bed. The third crank controls the elevation of the entire bed frame.
Best for: Patients who require more complex positioning, or for caregivers who need to adjust the bed’s height to make it easier to transfer the patient or perform other care tasks.

Cranks	Two manual cranks, typically at the foot of the bed.	Three manual cranks, also found at the foot of the bed.
Adjustments	Backrest: Adjusts the head section to allow the patient to sit up. Knee section: Adjusts the leg rest for elevation and comfort.	Backrest: Adjusts the head section. Knee section: Adjusts the leg rest. Bed height: Adjusts the overall height of the bed to a comfortable level for both the patient and caregiver.
Advantages	* More affordable than 3-crank models. * Simpler design is practical for short-term use.	* Offers improved ergonomics for caregivers, as they can raise the bed to avoid straining their backs. * Adjusting bed height makes patient transfers safer.
Considerations	The bed height is not adjustable, so caregivers must manually bend over when assisting patients.	The patient may need assistance to adjust the cranks, as they are located at the foot of the bed.

Optimal use tips for all manual crank beds

Prevent injury with locking casters. Before cranking the bed, always ensure the caster locks are engaged. This prevents the bed from rolling and potentially causing an injury.
Position cranks properly. When not in use, ensure the cranks are tucked away in their brackets to prevent tripping hazards.
Prioritize caregiver ergonomics. Position the bed at a comfortable height before beginning care to prevent back strain. With a 3-crank bed, use the height-adjustment crank to lift the bed to waist level.

How to use a 2-crank bed

Adjusting the headrest: Turn the appropriate crank clockwise to raise the head section, or counter-clockwise to lower it. This can help the patient sit up for meals or reading.
Adjusting the knee section: Use the second crank to adjust the patient’s leg position. Elevating the legs can improve circulation and reduce swelling.

How to use a 3-crank bed

Adjusting the head and knee sections: Use the first two cranks just as you would on a 2-crank bed.
Adjusting the bed height: Use the third crank to raise or lower the bed. Turn the crank clockwise to lift the bed and counter-clockwise to lower it.

General safety and maintenance tips

Prevent bedsores. For patients who are in bed for extended periods, reposition them regularly to relieve pressure. Use pressure-reducing mattresses or overlays and keep their skin clean and dry.
Maintain the crank mechanism. Regularly inspect the crank and lubricate moving parts to ensure smooth operation. Check for any loose parts or signs of corrosion.
Inspect and clean the bed regularly. Wipe down the frame and mattress with a mild soap and water solution. Always follow the manufacturer’s cleaning instructions.
Check weight capacity. Confirm that the bed’s weight capacity is appropriate for the patient, mattress, and any other items on the bed to ensure safety.

Use Each Crank Gradually: Avoid sudden adjustments to ensure safety and comfort.
Monitor Patient Posture: Regularly check patient position to prevent pressure sores.
Train Caregivers: Educate staff or family members on proper crank use.
Combine with Accessories: Cushions, overlays, and side rails enhance safety and comfort.
