Description

Technical Field

[0001] The utility model relates to the technical field related to construction tools, in particular to a construction wheelbarrow. Background Art

[0002] Construction trolleys play an important role on construction sites. With their sturdy structure and stable wheels, they can easily move heavy materials such as bricks, cement, and steel bars to designated locations, saving workers a lot of time and energy. In addition to carrying items, trolleys are also versatile. They can be adjusted in height and angle to suit different work needs. For example, sometimes a trolley can be used as a workbench to facilitate workers to perform aerial work; it can also be used as a temporary toolbox to store tools and materials, helping workers keep their work area clean and tidy. Trolleys also play a key role in safety. They provide a stable carrying platform, reducing the risk of workers falling and slipping during handling.

[0003] Existing construction wheelbarrows may need to be operated uphill during use. During the uphill operation, workers may be unable to keep the wheelbarrow balanced due to exhaustion, and the wheelbarrow will slide down the slope, which may cause the wheelbarrow to lose control and balance. For this reason, we propose a construction wheelbarrow. Utility Model Content
