[0002] An electric forklift is a forklift that is powered by electricity and is widely used in warehousing, logistics, and manufacturing. Compared with traditional internal combustion forklifts, electric forklifts have the advantages of being environmentally friendly, low noise, and low maintenance costs. An electric counterbalanced forklift is a specially designed forklift that uses electric drive and a counterbalanced weight system to maintain stability and increase load capacity.

[0003] Electric counterbalanced forklifts have good balancing performance, which gives them a higher load capacity and are widely used in warehouses and logistics centers, ports and docks, etc.

[0004] Existing electric counterbalanced forklifts have the following drawbacks: their simple overall structure and lack of a steering protection mechanism on the forks. As the electric counterbalanced forklift moves or turns, the cargo on the pallet outside the forks will sway due to inertia, potentially causing it to fall. To address this issue, we propose an electric counterbalanced forklift with a steering protection mechanism. Utility Model Content

[0014] Furthermore, reserved grooves are provided on both sides of the frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the electric counterbalanced forklift lifts the pallet with goods on it through the forks, the reduction motor is turned on to drive the screw to rotate. The rotation of the screw pushes the internal thread slider up and down, thereby driving the blocking mechanism to move up and down. The side plate height is adjusted according to the height of the goods stacked, so that the goods stacked on the pallet can be blocked from both sides.

[0017] The connecting rod is adjusted at one end of the sleeve and can be extended and retracted, making it easy to adjust the distance between the connecting plates according to the stacking height of the goods. Tighten the fixing bolt so that one end is inserted into the slot to fix the connecting rod after it moves up and down;

[0018] This electric counterbalanced forklift with a steering protection device uses a reduction motor to drive the lead screw to rotate, pushing the internal threaded slider and side panels up and down.
