Improved forklift hydraulic transmission cooling system

Currently used electric forklift trucks hydraulic transmission cooling system, hydraulic transmission oil cooler and more will be built into the engine radiator water pipe band room. Existence of such a cooling method following three questions: First, start early hydraulic transmission oil temperature is low, the oil viscosity, low transmission efficiency; the second is when the harsh working conditions, hydraulic transmission oil temperature is too high; three hydraulic transmission oil and coolant easy mutual string chamber. In response to these problems, decided to battery powered forklift hydraulic transmission cooling system improvements.
1. The installation of the thermostat

In order to solve the initial start YTO rough terrain forklift hydraulic transmission oil temperature is too low, increase a thermostat in hydraulic transmission oil cooling system circulation path. According hydraulic transmission oil level, the thermostat can automatically change the range of hydraulic transmission cycle oil (large circle or small cycles), adjust the cooling capacity of the cooling system to ensure proper hydraulic transmission gearbox oil temperature in the range of the work.

When the truck started working, hydraulic transmission oil temperature is below 70 ℃, hydraulic transmission oil small cycles. Transmission oil pump under the action of the torque converter, the torque converter oil outlet into the thermostat, thermostat oil outlet C closed without oil radiator fluid torque converter directly back to form small loops so that the hydraulic transmission oil rises rapidly to the proper operating temperature.

Hydraulic transmission oil temperature rose to 70 ~ 80 ℃, the thermostat oil ports A and C while the oil port in a semi-open state, then part of the hydraulic transmission oil through the oil outlet thermostat C to radiator cooling and then into the torque converter, and the other part hydraulic torque converter transmission oil directly return, while large circulation and small cycles.

High Mast Diesel Forklift Maintenance off road rough terrain forklift

Must adhere to the principle of prevention,All Terrain Forklift maintenance usually will be in the end,rough terrain trucks can effectively prevent the occurrence of the problem before forklift truck maintenance. So to maintenance institutionalized, standardized and scientific efforts to improve the efficient use of forklift trucks. Maintenance divided run-in period and maintenance, forklift routine maintenance,

battery operated forklifts

 seasonal maintenance, storage maintenance and regular care and other five. Today with the running of maintenance based.
Forklift new factory or overhauled within the time prescribed running-job use, known as forklifts run-in period. Internal combustion forklifts run-in period of work is characterized by: Parts machined surface is rough, poor lubrication, increased wear, rough terrain forklifts easy to loose fasteners, provisions must be run-in period for maintenance and use in accordance with the internal combustion forklifts.
Run-in period of internal combustion forklifts: Start with 50-hour break-in period.
Run-in period, three tons of internal combustion forklifts from the weight must not exceed 600kg, lifting height is generally not higher than 2m. Speed ??of the engine shall be high speed, speed limiting device shall be adjusted or removed, the speed should be maintained at 12km / h or less. In accordance with the proper use of fuel and lubricants. The right to correct start driving and operating the engine warm-up to more than 40 degrees in order to start; started to have a smooth, until the temperature to normal after an upshift; suitable shift, avoid crashing; choose a good road; try to avoid the emergency brake; Use close attention to the process of transmission, drive axle, wheel wheelchair, brake drum temperature; when loading and unloading operations, strictly abide by the rules.
