This lightweight large grab takes
large samples in soft bottoms. Its long lever arms and sharp cutting
edges on the bottom of the scoops allow it to cut deep into softer
bottoms. The closing mechanism is our patented self- releasing pinch-pin™
attached to the two closing arms which holds the grab open before
it hits the bottom. Upon impact, the tension on the chains is released,
which releases the pinch-pin™. The chain pulls the closing arms
together to close the scoops when the cable is lifted. The top of
each scoop is covered with 583 mm stainless steel screen for water
to flow through during descent. The screen is covered with a neoprene
rubber flap to prevent sample washout during retrieval. Operation
requires 1/8" cable (61-B) and winch, not included. Ship wt:
67 lbs. |
