Brief Introduction of the Tester:
HJY-1000B manhole cover tester was designed and manufactured according to industrial standard
and national standard such as CJ/T3012-1993<<CAST IRON MANHLOE COVER>>,CJ/T121-2000<<REGENERATIVE RESIN COMPOSTIE MATERIAL MANHOLE COVER>>,and JC889-2001<<STEEL FIBER REINFORCED CONCRETE MANHOLE COVER>>,GB23858-2009<<MANHOLE COVER>>,which is used for testing the load capacity of a manhole cover.The structural performance of the tester completely comply with the requirements of all the standard and criterion,in the mean time,it also meet the requirement of the European standard:BS EN 124-1994.
MAIN TECHNICAL DATAS:
1,maximum testing force: 1000KN
2,effective testing space: 1500mm×1500mm
3,height of the workbench to the ground: 500mm
4,force value precision:≤±1%(prior to 1grade)
5,load-adding speed regulating range: 0.1~25KN/s(manually stepless regulating)
6,piston stroke:350mm
7,load indicating precision: 0.1KN
8,load-adding method: electrohydraulic
9,Load-adding control method: manually stepless regulating
10,load-adding medium:46# or 68# anti-wear hydraulic oil
11,motor power: 0.75KW
12,power source requirement: 380V/220V/50Hz
13,machine dimension: L2000mm×W1500mm×H1500mm
14,machine weight: 3000Kg
MAIN FEATURES:
1,High rigid structure was adopted which ensure the safety during a test.
2,The loading cylinder is set on the top, and the height of the worktable to the ground is 500mm, which is convenient for taking and placing the manhole cover specimen.
3,A ball hinged connection is adopted between the rigid cushion block and the pushing end of the piston to ensure the authenticity of the measured bearing capacity.
4,A special material is used for sealing between the cylinder and the piston to achieve the effect of high sealing, low friction and long life.
5,Adopting professional oil pump motor unit special for tester, low noise and long life.
6,The ultra-fine oil filter is used to ensure the cleanliness of the oil circuit system so as to ensure the long-term work of the control actuator.
7,Digital display, real-time display the current force value, peak value, and load-adding speed.
8, No need foundation, just concrete ground is ok.
