TheAdvanced RobotSeries
All larger robots - starting from the W721/W821 models - are designed with a moveable kick-stroke beam which is guided directly in main carriage. The reduced moving mass allows high acceleration and deceleration for extremely short cycle times.
W721/W821 - W723/W823 TheCompactSeries
- W72J/W821
The vertical arm consists ofa rigid aluminum extrusion and guided by heavy-duty linear bearings and driven by a servomotor via belt to allow high speeds and short removal times.
- W723/W823
TelescopicVertical Axis: The gripper is mounted in front ofthe telescopic arm allowing for a very short length, for minimum overall height and fast movements.
W731/W831 - W732/W832 TheMiddleSeries
The larger rugged steel main beam on models W732/W831 and W732 /W832 allows for a wider distance between the main bearings and therefore longer kick-strokes up to 900 mm (35.4") with a 1,190 mm (46.9") reach and longervertical strokes up to 1,600 mm (63").
W73J/W831
The W731/W831 use the same vertical arm design as is used for the W721/W821 butwithverticalstrokesupto l,400mm(55").Due tothehigh operating speeds ofthe vertical arm and payloads up to 10 kg (22lbs), the W731/W831 is one ofour bestsellers for machines up to 500 tons.
- W732/W832
The vertical arm is a rigid aluminum extrusion with two high load linear bearings and a maximum length of 1,600 mm (63"). Designed for payloads up to 20 kg W731
(44 lbs) and offering a high torque C-axis rotation for placing, the W732/W832 is a popular robotfor insertjobs.
