Cutting Cables Using Portable Radio Controlled Hydraulic Cutting Units from Cembre

Portable Radio Controlled Hydraulic Cutting Units – B68RC3 Series

NEW Hydraulic Cutting Units – Radio Controlled B68RC3 Series

Thorne & Derrick distribute a range of cable cutting and crimping tools from Cembre, including the new B68RC3 series of Hydraulic Cable Cutting Units.

Hydraulic Cutting Units

Portable Radio Controlled

Hydraulic cutting units, from the B68RC3 range, are fitted with a unique wireless sensor paired to the receiver integrated in the pump using European frequencies (868 MHz).

The sensor is maintenance-free as it is fully protected and has battery-free technology.

All RC heads are fitted with eyelets to hang the head for better support during operation, and grounding point is provided to facilitate the grounding of the head when cable cutting is required.

The Cembre B68RC3 range of hydraulic cutting units features 3 variations: the B68RC3-85, B68RC3-96 and B68RC3-120. Each variation of the radio controlled cutting units have different cutting diameter ranges.

Radio Controlled hydraulic pump

The new portable pump B68M-P18-KV-RC3 is the core of every hydraulic cutting unit, which is battery operated for independent use.

The B68M-P18-KV-RC3 has the same inherent strength as the Cembre range of 18V tools – including the range of Hydraulic Cable Cutting Tools. The pump is a lightweight and of high capacity, equipped with an innovative radio remote control designed specifically for man-hole environments to allow operators to control and operate the pump out of the man-hole at a safe distance.

B68M P18 KV RC3 Portable Pump

New Li-Ion 18V 7Ah batteries used in the hydraulic pump provide high capacity while improved operating speed results from a revitalised hydraulic system with double speed action, and a maximum pressure sensor assures greater precision and repeatability of the pressure cycle, while a security valve doubles the provision for operator safety.

The unit is fitted with a patented unique system for stopping the pump when the cutting head sensor signals that its blades have travelled fully. At this point the LED indicator and buzzer notify the operator of the successful completion of the cutting operation.

For this reason, each pump is paired to its specific cutting head only and it must be considered as a complete unit.

A manual pressure release button is installed in case of emergency. Easy access to the oil reservoir is by means of an oil top-up inlet.  The innovative remote control function is able to work in man-hole environment where radio communication is normally more complicated.

Cembre B68RC3 Cable Cutting Tools

The unit features an OLED display to provide essential real time tool operating information including:

• Operating mode selection (cutting or crimping)
• Release mode selection (Smart release, manual release)
• Minimum set pressure and momentary pressure reached in bar/psi to allow verification of correct operation
• Battery charge level
• Number of cycles performed
• Number of cycles before scheduled recommended maintenance
• Motor temperature
• Operating command (radio or manual)

The unit has a secondary operating trigger which can be selected through the OLED display in the case that it is needed – the unit is fitted by dielectric oil for operator protection in case of cutting cables that may be accidentally live.

Each radio remote control is paired to only its specific pump.

Designed with improved handling characteristics for convenience and manageability, the Cembre B68M-P18-KV-RC3 cutting unit has a fibreglass-plastic shell with high resistance to wear and damage.

Hydraulic Pump Operating features

• 20 meters radio control operating range
• Intelligent auto-return at the end of the cycle (Smart Release)
• OLED multifunctional display with touch button
• Electronic Pressure Sensor (EPS)
• SMARTOOL technology for viewing and downloading operational data
• Wireless blade sensor (no batteries)
• Double acting with radio control or manual intervention
• Pressure release button
• Audible and visual indication of operational progress, completion and alarms
• Anatomical shaping for more convenient and practical handling
• Li-Ion 18.0 V-7Ah rechargeable high capacity battery
• Automatic battery connection system with release button
