Is it safe to transport liquid nitrogen tanks? The design of wheels, handles, and shock absorbers cannot be ignored.

The safe handling of liquid nitrogen tanks is not a trivial matter, and a reasonable mobile design can effectively prevent the destruction of biological samples worth hundreds of thousands of yuan. Modern liquid nitrogen tanks can safely move low-temperature equipment weighing hundreds of kilograms through three key designs.

1、 Three elements of safe handling
Professional wheel system

Using solid polyurethane tires (diameter ≥ 15cm)

Each wheel has a load-bearing capacity of no less than 50kg

360 ° universal rotation design (with brake device)

Anti static treatment (surface resistance 10 ⁶ -10 ⁹ Ω)

Ergonomic handle

Height adjustable (suitable for operators of different heights)

Anti slip rubber wrapping (friction coefficient>0.8)

Double grip design (spacing 45-50cm)

Folding storage does not take up space

Multiple shock-absorbing structures

Spring suspension system (travel ≥ 5cm)

Silicone buffer pad (Shore hardness 40-50A)

Center of gravity optimization design (low center of gravity+wide wheelbase)

2、 Safety handling data indicators
Tilt angle: ≤ 15 ° (liquid nitrogen may overflow if exceeded)

Mobile speed: ≤ 0.5m/s (emergency stop distance ＜ 0.3m)

Vibration test: Through 3G acceleration vibration experiment

Drop test: No damage from a 30cm height drop

3、 Operating standards
Checklist:

Confirm wheel brake unlock

Check the locking status of the handle

Ensure the verticality of the tank body

Key points for transportation:

Two people working together (with a capacity of over 50L)

Avoid slopes and bumpy roads

Special carts are used for long-distance transportation

Prohibited behavior:

Unilateral lifting (may cause vacuum failure)

Dragging movement (damaging the bottom insulation layer)

Overloaded stacking (affecting stability)

Experimental data from a certain laboratory shows that a high-quality handling system can reduce transportation accident rates by 83%. Special reminder: When there is abnormal frosting on the tank or the vacuum indicator changes color, it is necessary to immediately stop moving and contact the manufacturer for maintenance. Choose liquid nitrogen tanks with CE certification and UN certification, whose handling system has undergone rigorous testing to provide double protection for your precious samples.
