When using a stainless steel manual trolley for lifting assistance, it is necessary to comprehensively ensure safety from four aspects: operating standards, equipment matching, environmental assessment, and emergency measures. The following provides specific guidance based on industry standards and practical experience:

1、 Safety operation standards

Personnel qualifications

Operators need to undergo professional training, hold a lifting operation certificate, and be familiar with equipment performance and signal command specifications.

It is strictly prohibited to operate without a license, and a safety briefing (such as gestures and whistle sounds) must be conducted before starting work.

Equipment inspection

Handcart inspection:

Confirm that the stainless steel frame has no cracks, the welding points are firm, and the thickness of the load-bearing parts (such as the crossbeam) is ≥ 3mm.

The wheels need to rotate flexibly and the locking function should be normal (especially for medical carts that need to prevent slipping).

Inspection of lifting equipment:

The steel wire rope/sling has no broken wires or wear, and the hook safety device is effective.

The electric hoist needs to test the limiter and emergency stop function.

Lifting execution

Center of gravity control:

The goods should be placed in the center, with a center of gravity height ≤ 2/3 of the cart height, to avoid overturning.

Irregular items are secured with straps, and protective pads are added to sharp edges.

Operation taboos:

Overloading is strictly prohibited (refer to the rated load capacity on the trolley nameplate).

To avoid sudden acceleration/emergency stop, two people need to work together when the slope angle is greater than 15 °.

2、 Equipment compatibility matching

Material collaboration

Prioritize choosing 316L stainless steel carts (containing molybdenum elements) to adapt to possible metal friction and spark scenarios during lifting (such as chemical plants).

In medical scenarios, anti-static carts (conductive wheels+grounding chains) should be selected to prevent static electricity during the lifting of medical equipment.

Structural adaptation

The recommended height for the trolley armrest is 85-95cm (ergonomic) to facilitate the operator's observation of the lifting status.

Install modular interfaces (such as quick hooks) to seamlessly connect with lifting straps, balance beams, etc.

dynamic test

The new equipment needs to undergo full load dynamic testing: move it 10 times under simulated conditions (such as bumpy roads) to check if the connectors are loose.

3、 Environmental risk assessment

Ground conditions

Check the flatness of the ground (with a 3m ruler to detect gaps ≤ 5mm), and any depressions should be leveled in advance.

Anti slip pads (such as rubber mesh plates) with a friction coefficient of ≥ 0.5 should be laid in oil contaminated areas.

space limitation

Narrow passages (width<1.2m) require the use of folding carts and the deployment of dedicated personnel for guidance.

A safe distance should be reserved in the lifting area: there should be no obstacles within 1.5m and no suspended pipelines above.

meteorological monitoring

Stop working when the wind speed exceeds level 4 or visibility is less than 50m. After thunderstorms, check the insulation of the electrical components of the trolley.

4、 Emergency response plan

Equipment failure

Wheel stuck: Immediately stop moving and slowly adjust the position by inserting a pry bar into the wheel gap to avoid deformation of the frame caused by strong pulling.

Sling breakage: Personnel should immediately evacuate from the falling radius (calculated at 1.5 times the height of the cargo) and use backup rigging.

Personnel protection

Operators are required to wear safety helmets and anti smashing shoes, and in medical settings, goggles (to prevent splashing of medication) should be worn.

Equipped with first aid kits (including tourniquets and burn ointment), and dedicated safety personnel are required in work areas with more than 50 people.

Incident Response

Develop a three-level response mechanism:

Level 1: Minor collision (trolley deformation<5mm), on-site recording and replacement of damaged parts.

Level 2: Cargo falling (no casualties), blockade the scene, and submit an accident report within 24 hours.

Level 3: Personnel injured, immediately initiate medical rescue (cardiopulmonary resuscitation, hemostasis), contact 120 within 10 minutes.

5、 Maintenance and upgrade suggestions

Regular maintenance:

Check the axle clearance monthly (normal<2mm) and replace the lubricating grease (food grade) every six months.

When the lifespan of the trolley is greater than 3 years, magnetic particle inspection is required for the welded parts.

Intelligent upgrade:

Install a tilt sensor (warning tilt>5 °), and the medical cart can integrate RFID tags for drug traceability.
