Hytools NZ testable torque range is from 50 to 20000 ft lbs with the use of three Mountz transducers.
Hydraulic Torque Wrenches and Tools from ½" drive to 2-1/2" drive can be applied to the transducers. Mountz transducers are manufactured in the United States and are known among members of the industry as the nation's premier torque test tool supplier.
We calibrate and test: Battery Torque Gun, Torque Multipliers,Hydraulic Torque Wrenches, Manual Torque Wrenches, Hydraulic Pumps, Air Torque Guns and more.
They are an ISO 9001 certified and ISO 17025 accredited company. Mountz test tools comply with ISO6789:2003 and are constructed from high quality materials, engineered for superior reliability and safety and are recalibrated in their factory every 12 months.
Tested tools are issued with a certificate that is valid for a period of 1 year. If a replacement tool is required then Hytools NZ have a range of torque wrenches available for sale or hire.
The BMX20000 transducer will test torque wrenches from 2000 -20000 ft lbs (2700 -27000 Nm). Drive sizes available are from 1" to 1-1/2". This unit is for testing hydraulic torque wrenches. Tested tools are issued with a calibration certificate as well as a torque versus pressure chart.A run down adaptor is also available for this transducer so constant rotation torque tools can also be tested.
Hydraulic Jack Testing and Calibration
Hytools NZ is now able to offer hydraulic jack calibration and testing within their Onehunga workshop. The new test and calibration rig can safely accommodate loads up to 700 tonnes and the maximum diameter of cylinders that it can accommodate is 580mm with a maximum height of 2600mm.
An increase in industry requirements for calibrated jacking systems led to the development of this test rig as larger jacking systems, requiring calibration, had to either be shipped to the south island or alternatively to Australia. In some cases certification on a system is required after every six months which is extremely costly as well as inconvenient for the engineering contractor involved.
Once a jack has been calibrated to its dedicated gauge the data is processed and the relative graphs and certificates are then provided for the customer.
The rig is also used for pressure testing hydraulic jacks from 50 tonne through to 700 tonnes. Once a jack has been serviced it can be pressure checked throughout its stroke.
To protect operators against any possible mechanical or hydraulic failure, the test rig is surrounded by an all steel cage and lined with polycarbonate sheeting to protect against oil leakage. Operators are further protected by a separate solid steel screen set away from the cage where they can safely operate hydraulic pumps and monitor the digital transducers
