How to Maintain a Sand Dredge as Winter Approaches? Qingzhou Yongsheng Environmental Sediment Removal Equipment Co., Ltd. has been engaged in the production of sediment removal equipment for many years and is well-versed in this area. Now, let us introduce it to you.

1. Maintenance items every 100 hours: Arm cylinder head pin; Arm foot pin; Arm cylinder rod end; Boom cylinder head pin; Arm and boom connecting pin; Boom cylinder rod end; Bucket cylinder head pin; Half-shaft connecting pin; Bucket and bucket cylinder rod end; Bucket cylinder head pin; Boom linkage connecting pin; Check oil level in the swing mechanism box (add engine oil); Drain water and sediment from the fuel tank.

2. Every 250-hour maintenance item includes: Check the oil level in the final drive unit (add gear oil); inspect the battery electrolyte; replace engine oil pan oil and engine air filter; lubricate the rotating bearing (2 locations); check and adjust the tension of the fan belt, as well as the air conditioning compressor belt tension.

3. Maintenance items every 500 hours. Simultaneously perform maintenance items every 100 and 250 hours; replace fuel filter; check the height of grease in the rotating small gear (add grease); inspect and clean the radiator fins, oil cooler fins, and condenser fins; replace hydraulic oil filter; replace oil in the final drive box (only at 500 hours, then every 1000 hours thereafter); clean the internal and external air filters of the air conditioner system; replace the hydraulic oil breather filter core.

4. Long-Term Storage: When storing machinery long-term, to prevent rust on the hydraulic cylinder piston rod, the working unit should be placed on the ground; after the entire machine is cleaned and dried, store it in a dry indoor environment; if outdoor storage is unavoidable due to conditions, park the machine on well-drained concrete ground; fill the fuel tank before storage, lubricate all parts, change the hydraulic oil and engine oil, apply a thin layer of grease to the exposed metal surface of the hydraulic cylinder piston rod, disconnect the negative terminal of the battery, or remove the battery for separate storage; add an appropriate amount of antifreeze to the coolant based on the ambient temperature; start the engine once a month and operate the machine to lubricate all moving parts, and simultaneously charge the battery; turn on the air conditioner's cooling function for 5-10 minutes.
