Hydraulic Jacks

Hydraulic jacks are mechanical devices that utilize hydraulic power to raise heavyweight loads, typically by hand, air (compressed air), electricity or gasoline power. There are various types available and each can be powered via hand control or another means such as compressed air (compressed), electricity or gasoline.

Start by making sure the jack is lowered and its release valve open, and pump its handle several times to allow trapped air to escape. This should help the process go more quickly.

Early Life and Education

Coho (salmon) juveniles that have undergone the smoltification process for 18 months typically migrate downstream towards the ocean where they feed, with males known as jacks taking an outsized share in this migration. Males that reach maturity early before moving downstream, known as mini-jacks, may cause harm to wild and hatchery coho populations.

Quilcene National Fish Hatchery uses jacks as bait for European green crab traps placed across its refuge. Though they have little chance competing against larger three-year-old males for females, jacks can still “sneak up” behind safer distances to fertilize eggs that will prevent predatory European green crab populations from taking root in a given location.
