Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a trolley and particularly to a hand operable lifting trolley.
Description of Related Art
[002] Cement is a fundamental material in construction, widely used for various applications including concrete production and mortar mixing. The transportation of cement within construction sites, particularly in scenarios where the material must be moved over distances or to elevated locations, presents logistical challenges. Current methods often rely on manual labor, which can be physically demanding and potentially hazardous due to the weight and bulkiness of cement bags or containers.
[003] While conventional methods employing hand trucks or manual lifting may serve the purpose, they are associated with inefficiencies, potential worker strain, and increased risk of accidents. Motorized lifting solutions exist, but they tend to be expensive, and complex, and may not always align with the specific needs of construction sites, especially in cases where space is limited.
[004] US7500681B2 discloses a ‘Collapsible carrying trolley’. However, the disclosed prior art is neither strong nor sturdy.
[005] In light of these challenges, there is a compelling need for a specialized lifting trolley designed to address the unique requirements of cement transportation within construction environments.
[006] There is thus a need for an improved and advanced hand operable lifting trolley that can administer the aforementioned limitations in a more efficient manner.
SUMMARY
[007] Embodiments in accordance with the present invention provide a hand operable lifting trolley. The lifting trolley comprising: a frame comprising a vertical bar, primary slated bars, secondary slanted bars, and elongated bars, wherein the primary slated bars, and secondary slanted bars are rested on the elongated bars. The lifting trolley further comprising: a tray arranged in between the elongated bars, wherein the tray comprises a base, and up-raised walls extending from the base at three sides of the base. The lifting trolley further comprising: primary handles extended from the elongated bars for easy gripping by a user.
