Q:What role does the tower crane torque limiter play?: The overload protection of tower crane is protected by two equipment, lifting load limiter and torque limiter. The latter generally in the big arm root 4-5 meters to the front of the large arm, overloading (Chao Liju) work, it is more important, basically, the scope of work is torque limiter plays a protective role. While the former is the weight limiter function in the arm root within 4-5 meters, because the tower crane is a jib type crane, each allowing weight lifting position corresponding to the different (CAB load curve). For example, such as 63KN.M, the big arm root 2 meters lifting, the theory is 23 tons, while the torque limiter is not over, but in fact, the tower crane at early crouched down, so the weight limiter in this work.

Q:My dad has some old tools and he is wondering if the company is still around, or what happened to it. A yahoo search revealed little.: Found on - www.lathes .uk/boicecrane/ Boice-Crane - USA Boice-Crane (Wilton Division) made various types of power tools, including a selection of wood lathes intended for amateur and educational use, and in the 1940s and early 1950 their range included, amongst others, the two amateur and one professional or educational machines illustrated below. The more robust lathe of the amateur pair had a 50 inch long bed with 10 swing and able to take 34 between centres; the 4-step V pulley in the headstock could be driven from either from the rear, or underneath. The bed, which had a gap able to swing 14, was internally ribbed and machined on its top surface. The No. 1 Morse taper tailstock was fitted with self eject for the centre. The double-ended spindle was 1.25 inches in diameter and ran on ball bearings - whilst the single faceplate contained two different diameter, left and right-hand threads so that it could be screwed onto either end. The lathe weighed 115 lbs, so, despite an insubstantial appearance, must have been a reasonably robust machine. The other bench lathe had a bed built from two steel channel sections - with the most elementary type of headstock and tailstock. The capacity was 10 x 30, the weight 30 lbs and the headstock spindle carried a 4-step, overhung, V-belt pulley. The company are now: Gothenburg Manufacturing Co., P.O.

Leatherjackets were very common round here, and are a favourite food of the local crows .These leatherjackets transform into crane flies.Summer is their growth time.

Q:i know something is supposed to happen when you make a thousand origami cranes but i dint remember what happens. can someone please help me: It's a story about a japanese girl who was diagnosed with leukemia. The story goes, if are diagnosed with leukemia and are able to fold a 1000 paper cranes before you die, you will live. This theory actually works the way horoscopes do. It's not that the making of paper cranes makes you healthy, it has to do with the amount of time it takes. If you survive that long, then you have passed the critical death points and will live anyway, whether you make a thousand of them or not. Plus, it gives you something to do a a healthy, short-term reason to live, which always helps the healing process anyway.
