Handheld Tongs

The TOX®-Handheld Tongs have been designed with the operator in mind: robust, durable and excellent handling due to:

• flexible hose connection to the pressure intensifier
• well thought-out rotary coupling for oil, air and electric
• sturdy, swivelling hanging bracket for attachment of a balancer
• service friendly

Some of the handheld tongs shown here can also be used as machine mounted units, which are supplied with tapped mounting holes instead of handles.

CHH 03.45 & CHH 03.75 Handheld Units

• press force 45 kN/75 kN at 250 bar oil pressure (5/8 tons at 3600 psi)
• heavy duty C-frame unit with axial joining direction
• available with 1- or 2-hand controls
• can also be ordered as machine mount units
• hydraulic pressure is provided by a pneumatic operated TOX®-Pressure Intensifier PHA

The TOX®-Handheld Tongs CHH 03 are also ideal for punching or marking applications.

CMH 03.45 Mini-Handheld Unit

• press force 45 kN at 470 bar oil pressure (5 tons at 6900 psi)
• C-frame unit with axial joining direction
• can be used as a portable handheld unit for mobile applications
• available with 1- or 2-hand controls
• use in machines either fixed mount or with an indexing slide
• special frames with 50, 75 and 100 mm throat depths

Drive combinations for CMH 03.45

• Mini-handheltd tongs type CMH 03.45 are driven by a pneumohydraulic intensifier and a TOX®-Hydraulic Cylinder HZ 40.
• For model 10 with 1-hand controls and a tool opening of 6 mm or model 11 with 14 mm stroke and 2-hand safety control, the intensifier PHA 160.99 is used.
• For Model 12 with pneumatic control and 1-hand start, the intensifier BES 125.10 is used.

Other combinations are available, e.g. if more than one cylinder is attached to the same pressure intensifier.

Design versions of the TOX®-Mini Tongs

• CMH 01.45: Retractable unit with a press force of 45 kN at 6 bar air pressure (5 tons at 90 psi). Our versatile retractable unit was originally designed for joining of ventilation sheet metal ducts.
• CMH 02.30: Flange unit with a press force of 30 kN at 6 bar air pressure (3 tons at 90 psi). You can join small flanges using this super compact unit with solid punch and die.
• CMH 04.45: Mini-Handheld unit with a press force of 45 kN at 470 bar oil pressure (5 tons at 6900 psi). This rugged X-(scissor action) handheld unit, with lateral joining direction, comes equipped with a 1-hand control and a tool opening of 6 mm for safety.
• CHH 04.45: Handheld unit with a press force of 45 kN at 250 bar oil pressure (5 tons at 3600 psi). This rugged X-(scissor) handheld unit provides a tool opening of 6 mm (1/4 in) for safety.

There are many other versions and control system variations.

Accessories for CMH 03.45

• Self equalizing slide with stroke adjustment and pneumatic cylinder: The slide moves tongs back to clear the TOX®-Clinching Point or any embossment on the parts. Includes end position sensor. Optional end position dampers.
• Tongs with integrated punch stripper type CSR for clinching applications.
• Gimbal CZS or gimbal with hanging bracket: The handles for 2- or 1-hand cycle initiation can also be mounted on the frame. A special mounting adapter allows the handle to be rotated 360° and swiveled ±35°.

Accessories for CHH 03.45/CHH 03.75

• Available with rotary feed through CZS and suspension shackle.
• Can be equipped with a live ring and suspension shackle or live ring with hanger.

Depending on the unit type, the working cylinder of the TOX®-Handheld Tongs requires hydraulic pressure of 250 bar (3600 psi) or 470 bar (6900 psi). The simplest way to generate this hydraulic pressure is to use a pneumohydraulic TOX®-Pressure Intensifier, which boosts the compressed air pressure from 6 bar (90 psi) to the required hydraulic pressure. We offer two intensifier versions in different variations:
