SPECIFICATIONS:

• 1500kg load capacity with 100% full face jaw contact
• Full face jaw height and width: 100mm x 50mm
• 1/2 face jaw height and width: 50mm x 50mm
• Maximum ‘External’ OD clamp capacity (inside ‘FULL FACE’ jaws): 1140mm
• Maximum ‘External’ OD clamp capacity (inside ‘1/2 FACE’ jaws): 1250mm
• Inverted jaw clamping capacity (internal clamping): 1360mm (750kg max SWL)
• Table to chuck body stick out (inc. 15mm backing plate): 155mm
• Table to bottom of chuck jaw (inc. 15mm backing plate): 195mm
• Chuck back plate diameter: 1000mm
• Chuck weight inc. backing plate: 350kg
• Machined backing plate: Mounting hole mag drilled for table slots
• Jaw types: Standard (full jaw face) and inverted (1/2 jaw face)
• Grubs screws fitted in the chuck jaw adjustment rail to keep dirt out of threads

SAFETY NOTE

• ALWAYS factor in / deduct 350kg chuck weight and 195mm ‘stick out’ in relation to positioner load chart
• ‘External’ clamping = On the outside of the job ie. pipe / flange / steel
• ‘Internal’ clamping = On the inside of the pipe (jaws pressing outwards)
• Internal clamping only offers 1/2 the load capacity due to gripping issues / weight not pressing on jaws with full torque (as opposed to compressed external clamping)
• We do not recommend internal clamping 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 1/2 surface area (1/2 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
