First, pre-installation site assessment is a necessary prerequisite before any modification to electric pallet trucks. Facility managers and equipment operators need to map all running routes of electric pallet trucks in advance, mark narrow aisles with width less than 1.8 meters, blind corners blocked by storage racks, high pedestrian flow areas near rest zones and cargo staging points, and low-clearance sections with suspended pipelines. The assessment results will be used to confirm the optimal installation position, to avoid the situation that warning components are blocked by stacked cargo or hit by overhead facilities during daily operation.

For audible alarm installation, the components are required to be fixed on the upper non-load-bearing area at the front and rear of the truck body, no less than 30 centimeters away from any cargo carrying surface. The output volume of the alarm should be 10 to 15 decibels higher than the average background noise of the corresponding operation area, and controlled between 60 to 85 decibels in general warehouse scenarios, so that it can send clear warning signals to nearby pedestrians without causing excessive noise pollution to the whole facility. The alarm system should be set to automatically trigger when the truck moves forward, reverses or makes a low-speed turn, and reserve a dedicated manual test button for daily pre-shift functional checks.

For visual beacon installation, the standard mounting height is between 1.2 meters and 1.5 meters above the facility ground, which is higher than the average height of the operator’s head and will not be covered by pallets and loaded cargo during normal operation. The beacon should adopt steady or low-frequency flash mode with 60 to 120 flashes per minute, to avoid visual fatigue or dizziness for pedestrians who stay in the operation area for a long time. For special scenarios such as cold storage or damp chemical warehouses, operators need to select corresponding waterproof and low-temperature resistant beacon components to ensure stable operation under specific environmental conditions.

After completing the installation of alarms and beacons, facility teams still need to carry out regular quarterly inspection for all warning components, check for loose fixation, worn connecting wires or signal failure in time. Operators should not take the warning system as a complete replacement for on-site safety management, and still need to follow the facility operation rules to drive at a controlled low speed in high-risk areas. Standardized installation can effectively reduce the occurrence probability of pedestrian-vehicle conflicts, and support stable and efficient daily material handling operations.
