TPD-3200  Hydraulic Tractor Towable Road Grader

 

Introduction:

TPD-3200 is a hydraulic land grader which need to be front mounted to 75-120hp four wheel tractor,it is fully hydraulic steering gear. It is widely used for highway construction grading work, constructional engineering,water conservancy project, farmland construction, also can be used for clearing away weeds or snow.

 

Characters:

1. Low cost, price is only 1/10 of big land grader, but easy and convenient to

operate, flexible to use,  also safe and  reliable,good working  performance and high efficiency.

2. Short body, small turning radius, the machine drive and the ground operation performed by only one person, no longer need to cooperate by two persons, thus can drive with high proficiency.

 

Working Condition :

1. Temperature range: -20-80°C

2. Ordinary hydraulic oil YA-N68GB2512-81 is the suggested working liquid, or 11# in summer, 8# diesel engine oil(SY-1152-88) 

3. Filter rating: no less than 25micron

4. Oil temperature: working liquid temperature: 0-80°C, suggest to use 40°C~65°C.

5. Pressure of inlet opening: lowest pressure for continuous working is -0.017MPa,Highest pressure for continuous working is +0.1MPa.
