Let’s dive in.

1. What Is a 3-Crank Manual Hospital Bed?

A 3-crank manual hospital bed is a manually operated bed that uses three independent crank handles to control three functions:

1. Backrest (head elevation)

2. Knee section (leg elevation / knee gatch)

3. Overall height (hi-low adjustment)

Unlike single or two crank beds, the three-crank arrangement gives caregivers or users more positioning flexibility. In some designs, one crank might alternatively control Trendelenburg / Reverse Trendelenburg height instead of overall height.

Typical range of motion for cranks:

• Backrest: 0° to ~75°

• Knee section: 0° to ~40–45°

• Height: often ranges from ~500 mm to 750 mm above floor, or similar ranges depending on model

Because no motors are involved, manual 3-crank beds are less expensive to maintain and not vulnerable to motor failure.

2. Key Specifications to Compare

When evaluating 3-crank manual hospital bed wholesale offers, these technical parameters are crucial:

For example, a typical 3-crank manual bed offered by suppliers features these: 0–75° backrest, 0–40° knee, height adjustment, aluminum folding guard rails, detachable ABS boards, castors (~125 mm diameter)

3. Safety and Structural Features You Cannot Overlook

• Entrapment zones: The U.S. Food and Drug Administration (FDA) has identified seven zones of potential entrapment within a hospital bed system, such as between the rails and the mattress or within gaps in the rails themselves.
• Preventive measures: Look for bed rails designed to minimize these gaps. Some beds offer concealed, tuck-away, or full-length ABS (acrylonitrile butadiene styrene) rails, which are molded to prevent patients from getting a limb or head caught.
• Safe-use assessment: Be aware that bed rails are not safe for every patient, especially those who are confused or agitated and may attempt to climb over them. 

Braking system

• Central locking system: A centralized braking system is a superior safety feature that allows a caregiver to lock all four casters (wheels) with a single, easy-to-use pedal.
• Individual wheel locks: For more precise maneuvering in tight spaces, some beds also offer individual locking mechanisms on each caster.
• Durable casters: The casters should be heavy-duty and equipped with a locking system that is robust enough to hold the bed securely in place without slipping. 

Mattress compatibility

• Correct fit: Ensure that the mattress and bed frame you purchase are compatible as a system. The mattress should fit snugly within the bed’s frame and side rails.
• Mattress stoppers: Some beds include integrated, non-slip mattress stoppers to prevent the mattress from sliding as the bed is articulated.
• Support surface: A solid, perforated pan sleeping surface is often safer and more supportive than an older helical (spring-style) design, as it reduces pinch points and improves ventilation. 

Structural and mechanical features

Sturdy construction and weight capacity

• Heavy-duty steel: A robust frame made of high-strength, powder-coated steel is standard for stability, durability, and corrosion resistance.
• Weight capacity: Standard beds can typically support around 250 kg (551 lbs), but heavy-duty bariatric models are also available for heavier patients. Verify that the bed’s capacity is appropriate for your intended use.
• Welded frame: A welded frame indicates a more stable and sturdy construction compared to a bolted one. 

Crank mechanism reliability

• Smooth operation: The cranks should operate smoothly to allow caregivers to easily adjust the backrest, leg rest, and overall bed height.
• Concealed cranks: Features like concealed or foldable cranks prevent them from being trip hazards when not in use.
• Pneumatic assist: Some models may incorporate a pneumatic cylinder assist to extend the life of the crank mechanism and make operation smoother. 

Head and footboards

• Detachable and easy to clean: Look for boards made from ABS plastic that are durable, lightweight, and can be easily detached for cleaning or to assist with patient transfers.
• Bumpers: High-quality beds include bumper casters on the corners to protect walls and furniture from damage when moving the bed. 

Quality and standards

Compliance with standards

• International standards: Reputable manufacturers should adhere to international medical device standards, such as ISO or CE, which certify the bed’s safety and effectiveness. 

Manufacturer reputation

• Established vendors: When purchasing wholesale, it is vital to source from a reputable manufacturer or supplier with a proven track record to ensure consistent quality and access to support and warranties.

When buying wholesale, safety is non-negotiable. Here are critical features:

1. Side Rails / Guardrails
   Full-length or partial aluminum folding rails help prevent accidental falls. Panels made of ABS or aluminum are common.

2. Detachable Head & Foot Boards
   Ease of shipment, replacement and installation. Many beds allow tool-free removal.

3. Crank Mechanism Quality
   Use reinforced steel cranks, ergonomic handles, possibly with gear or gas-spring assistance to ease operation. Some models feature pneumatic assist to reduce operator effort.

4. Caster & Locking System
   Central or individual locking brakes improve stability. Castors are often ~125 mm (5″) in diameter for hospital floors.

5. Ventilated Bed Platform
   Perforated steel or ABS panels allow airflow beneath mattress, reducing moisture accumulation.

6. Finish & Corrosion Protection
   Powder-coated or epoxy finishes protect steel frames. ABS and aluminum parts resist rust.

7. Certification & Compliance
   For international markets, beds often need CE, ISO13485, or local medical device registration.

4. Wholesale & OEM Supply: Advantages and Tips

When procuring 3-crank manual hospital beds in bulk, here’s what matters:

• Factory Direct Pricing: Eliminates middlemen margin.

• MOQ (Minimum Order Quantity): Many suppliers require lots of dozens or hundreds.

• Customization / OEM: You can request bed dimensions, color, logos, paint, rails, etc.

• Spare Parts Support: Ensure availability of cranks, rails, boards, hardware.

• Quality Inspection & Samples: Always review a prototype before full production.

• Packaging & Shipping: Flat pack, knock-down design, protective corners.

• After-Sales Service: Guarantee frame, mechanical parts for specified years.

At Henyuan Medical, we offer flexible OEM support, spare parts availability, and global shipping for wholesale orders.

5. Sample Buyer Use Case

Use Case: A regional network of small clinics in Southeast Asia sought a reliable, economical manual bed solution. They ordered Henyuan Medical 3-crank manual hospital beds with:

• SWL 200 kg

• Dimensions ~ 2150 × 960 × (500–720) mm

• Full-length folding side rails
