Drawbridge
The drawbridge structure is a “working” model. You can use parts from the ME-6984 Structures Hydraulic System
(not included*) in order to raise and lower the drawbridge. Use #4 Beams or Flexible #4 Beams as cross members
on the bridge support section. Use two #3 Beams and a Straight Connector to build extra #5 Beams. Use two #2
Beams and a Straight Connector to make extra #4 Beams. Note: Additional members from PASCO Structures Sets
are needed in order to extend the right hand end of the bridge shown in the illustration.
(*See the PASCO catalog or the PASCO Web site at www.pasco.com for information about the
ME-6984 Structures Hydraulics System.)
