QTK40 SELF ERECTION TOWER CRANE
1.1 Brief introduction
The QTK40 model self erection tower crane is developed by our company on basis of years of experiences in production and new technical innovation.This tower crane is whole consignment & fast set-up vertical and level transport machinery. Mainly apply to 7~10 storey civil buildings. This machine also could used in factory, goods yard, station, ports to move products, as well as to be a mobile hoisting machine.
1.2 Features
The famous feature of this kind tower crane could realize fast-installation and whole consignment transportation. After whole enfolding of tower crane, two workers could transport tower crane by one truck crane (8ton), and the installation could be finished within 40 minutes.
Other features:
(1) Inner tower expansion in suit place, it could auto-lock and release
(2) lifting beam could auto-unfold or fold when towers stretch and unfold
(3) (Tower stretch and unfold, beam unfold, counter weight load ,which all could do range form 0~360°
(4) Adopt drum, whole steel wire rope pulley system, to realize lifting& installation set-up work
(5) Have two kinds interchange device: track and fixed supporting lug, to adjust different uses
(6) The angle of altitude of lifting beam is 15, then could increase the height of lift, but its Max lift weight is 1100kg .
(7) Lifting mechanism, trolleying mechanism and traveling mechanism adopt frequency & gear changable to control speed.
(8) Slewing gear adopt electric resistance control mode, smooth starting, with good positioning performance

FAQ of CMAX QTK40 Self Erection Tower Crane ,Inner Tower Expansion
What's other improtant advantages ?
1)Fast, simple and safe erection of small, light individual modules.
2)Excellent choice for narrow sites in the city as there is no need to pre-assemble the whole jib on the ground.
3)Stable funcion of Frequency Inverters and other electrical control systems for 3 main mechanism, and easy and convenient self repair and maintenance for the clients.
4)Twice ball blasting and twice painting for steel structure surface of CJ tower cranes, the hot-dip galvanizing process is used on the handrails, and the time limit of the galvanized quality assurance is 50 years.
5)Good at endurance, adapting to atrocious weather like higher of lower temperature, acid rain and typhoon.
- Q: I have a vessel 40 feet off the ground in a platform, and the crane can get to within 30 feet of it (from the side). I'm more curious of the process for sizing them though.
- As you won't be building your own crane (that would be stupid since you would be fully liable). Call a crane vending/renting company. They'll be more than eager to provide you with technical council. How you pick a crane? What do you need to do with it - type of crane for instance -Moving stuff around in a warehouse, yard,.. always at the same places = overhead crane -Lifting heavy stuff once (for instance another crane) or for a short period - mobile crane -lifting stuff for a longer period but not permanent (construction) = tower crane How much do you need to lift, what can it cost? ... It's al pretty simple
- Q: If I have one week, is that enough time?
- It all depends on how fast you can make one paper crane and how many hours you have available each day. If you made 15 an hour for 10 hours each day (150 cranes a day) for 7 days you would have 1050 cranes. You will probably find that you begin to go faster, the more cranes you make. However, after 2 or 3 days you will get sore hands and this will slow you down again. It's easier when you work as a team.
- Q: How to build a strong paper crane?
- Fact: paper is relatively strong when you pull on it, but when you push on it, it easily crumples. Build your crane out of several bars. Bars that are being pushed upon by the weight need to resist the crumpling. A good way to do this is to roll a sheet of paper into a tube form to make the bars. Bars that are only being pulled on don't need to be more than a sheet of paper. A frame cranes are simple to make: www.lni.wa /wisha/rules/generalsafety/images/24_d2_a-frame.gif
- Q: This is a new technology in ringging work. Hope anyone can give me some detail information about wireless crane scale.
- Hi, okorder for more information
- Q: when high rise buildings are built a crane is erected to lift iron and cement up. How do they erect these cranes?
- Like an Electra set, they are dismantled then put back together. They are transported in sections along with the counter balance weights. The most solid part is the cab.
- Q: How do cranes get put together?
- Hey Sir Fing, While watching a skyscraper being built here in San Diego, I asked the same question. For the tallest buildings, it is built in to the building and when they are finished, the top portion is lowered down. For a smaller building, it is assembled and hoisted by... A larger crane! Interesting, isn't it? Great question! James in San Diego
- Q: Formulas for calculating outrigger pad sizes, centre of gravity of loads, outrigger loadings
- If you are going to be operating a crane, you need to do this on your own. People's lives will depend on you having a good knowledge in this area. .
- 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.

- Q: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?
- Use trigonometry, it's a triangle of forces.
- Q: When should a crane be load tested?
- if crane using regularly more then 8 hrs test should be every 4 months 8 months and full sevice at 12 months............
