SPECIFICATIONS:

• Maximum OD clamp capacity (inside the jaws): 250mm
• 150kg load capacity with 100% standard jaw face contact
• Chuck body diameter: 300mm
• Weight: 20kg
• Machined backing plate: Mounting hole mag drilled for table slots
• Jaw types: Standard (full jaw face)
• Jaws must never go out beyond 50mm from the edge of chuck body

SAFETY NOTE

• Never clamp on the inside of the pipe diameter (external only). When warmed up, the pipe expands and will fall off
• Always grip the job inside the jaw surface area that has teeth grooves (not the smooth side)
• Load capacity varies subject to the jaw face surface area gripping to the job ie. flange or pipe
• If a flange is being gripped inside the jaws, the surface area will be less than the surface of pipe inside the jaws
• Inverted jaws only have 1/3 surface area (1/3 capacity) compared to standard full face grip
• The weight & stick out of the chuck must be factored into the welding positioner load capacity when fitted to the table
• Always check with Spectrum before clamping heavy loads inside chuck jaws to ensure safe grip

STANDARD JAW LOAD CAPACITY (UNSUPPORTED):

• 150kg @ 200mm maximum
• 75kg  @ 400mm maximum
• 30kg @ 600mm maximum
