Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a safety limit assembly for a logistics vehicle. Background Art

[0002] Logistics carts are unit mobile container equipment equipped with four casters for transporting and storing materials. They are often used in logistics distribution in large supermarkets or logistics turnover between factory processes, and are widely used in the logistics industry. As a production and handling tool, they can ensure that items are not damaged during the handling process and ensure the safety of workers. The weight is relatively light, the trolley is beautiful and practical, and has high maneuverability.

[0003] When loading and unloading goods, the conventional method is to lock the casters of the logistics vehicle. However, the locking of the casters has limitations and cannot effectively fix the logistics vehicle, resulting in sliding or tipping, which is dangerous. Therefore, we propose a safety limit assembly for the logistics vehicle. Utility Model Content
