- Q: Safety rules for tower cranes
- Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.
- Q: If you were to give someone a paper crane with an ayat or hadith (has to be short, as I have to write on its wings)... what would you write?I was thinking of writing this:Peace be upon you for what you patiently endured.

- Q: I don't really believe that the wish will be granted.Anyways I've really been into Origami and I remember reading in my Heroes book (slash the show) that a certain number of cranes means a wish. But before I start making all these cranes, I want to know if it's 100 or 1,000.So if you haven't gotten it in your head yet the question is:Is it 100 or 1,000 cranes to get a wish
- 1000 Cranes Wish
- Q: What kind of flower is the Sunset Crane?
- Okay, i'm going to get every backyard gardener east of denver jumping down my throat on this one, but it's time you all wake up and know the real name of one of your favorate potted plants. only then will you beleave me when i tell you the sunset crane is a type of geranium. the true geranium. not the plant most people know as the geranium is botanically Pelargonium. that silly looking, red flowered, fuzzy leafed thing everyone loves to stick in a pot by their front door every summer back east and mistakenly call a geranium is not really a geranium. even the fancy Martha Washington geranium is not a geranium. it is the Martha Washington Pelargonium. but whats the use? unless you are a botanist everybody back east is going to say i'm just another fruit cake from california. (born and raised in wisconsin i'd like to add) okay, your sunset crane is botanically a geranium, often called by it's common name cranesbill. okay, you have the real best answer, so go ahead and pick the wrong best answer from some smuck from back east who knows best. sure i have two post graduate degrees in science, been a univ certified master gardener for over 15 years and just might know a tad bit more then the eastern fair weather, summer time gardener. but don't let that prevent you from thinking i'm nuts and choosing a better, best answer. i'm used to it. grandma is always right... until her plant dies. then they call me for the real low down.

- (3) the lifting height limiter, lifting height limiter is used to restrict access to the hook jib head or trolley before, or is dropped to the lowest point (ground or below ground Ruoganmi) before the lifting mechanism of automatic power-off and stop working, to avoid lifting hook over hoisting device touch the boom and the bad.(4) the amplitude limiting device is used to limit the boom does not exceed the limit position in the pitch. An alarm is sounded when the lifting pitch reaches a certain limit, and the power is automatically cut off when the limit position is reached.(5) stroke limiter of car stroke limiter: a trolley type jib head and root, to cut off the circuit car traction mechanism, prevent car offside.
