Latch for tilting rotatable tower

摘要

An apparatus comprises a support and a tower pivotally attached to the support and movable relative to said support between a raised and a lowered position. The tower is rotatable to and from a predetermined position about a longitudinal axis thereof when the tower is the raised position. A latch device is displaceable between a secured position and a non-secured position, the tower being prevented from moving to the lowered position when the tower is raised and the latch device is in the secured position. A release system prevents displacement of the latch device from the secured position when the tower is not in the predetermined and raised positions. The release system permits displacement of the latch device from the secured position when the tower is in the predetermined and raised positions. The latch device includes a plunger and a biasing member located within a latch housing. The release system includes a contact element which is connected to the plunger.
