Light-spec electric pallet jack is widely applied in small and medium-sized warehouses, retail distribution centers and factory intra-site material transfer scenarios, featuring flexible operation and low daily operation cost. The continuous working hours parameter constraint is a core indicator that users need to pay close attention to during daily operation, as it directly relates to equipment operation stability, service life and workplace operation safety.

First, the core factors that determine the continuous working hours parameter constraints are derived from three major modules of the equipment. The first part is the power battery module, the state of discharge of the battery under high current continuous output will generate corresponding heat accumulation, and the parameter constraint will set the maximum duration that allows continuous discharge without triggering the overheating protection threshold. The second part is the drive motor module, the light-spec electric pallet jack usually uses compact high-efficiency drive motor, continuous long-time operation under load will lead to gradual rise of winding temperature, the corresponding parameter constraint is set to avoid the motor operating beyond its rated temperature rise range. The third part is the load bearing structure, long time continuous operation under full load will increase the wear speed of the pallet wheel and transmission parts, the parameter constraint of continuous working hours also reserves reasonable space for mechanical wear control.

Second, the reasonable setting logic of continuous working hours parameter constraint is linked with the actual load state of the equipment. Under the rated standard load state, the corresponding maximum allowable continuous working duration is set according to the heat dissipation capacity of each core component, operators are advised not to run the equipment beyond this duration without intermittent rest. When the actual carried load is lower than 50% of the rated load, the continuous working duration can be appropriately extended within the allowable range of the parameter specification, and users can refer to the official operation manual for corresponding adjustment reference. The parameter constraint also reserves reserved margin for high ambient temperature scenarios, when the working environment temperature is higher than 35 degrees Celsius, the allowable continuous working hours should be appropriately reduced to avoid abnormal heat accumulation of components.

Third, abiding by the continuous working hours parameter constraints can bring multiple practical benefits for users. It can effectively reduce the fault probability of equipment in daily operation, extend the overall service life of core spare parts, avoid unplanned shutdown that affects the whole material handling workflow. Operators can arrange reasonable shift handover and equipment intermittent rest plan according to the corresponding parameter constraints, match the proper battery charging and swapping schedule, so as to maintain stable and high efficiency of the whole material handling system for a long time.
