Product Description:

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

Q:How Much Can the Most Powerful Crane Lift?
Those stones are small compared to what cranes can lift. I did find this Liebherr the heavy equipment company have developed a new all terrain nine axle mobile crane that is the worlds most powerful. The Liebherr LTM 11200-9.1 has a maximum lifting capacity of 1,200 tons with its powerful 100 metre (328 ft) telescopic boom. another: Deira City Centre was the crane’s first lift as it assisted in completing the work in less than 30 hours in what would have otherwise taken an approximate 20 days. The monster machine can lift up to 1,200 tonnes and cover an area over 100m wide. The operational weight is 96 tonnes and the total counterweight is 202 tonnes. Average weight of the stones in the Great pyramid is 2.5 tonnes. So either of those cranes could lift over 400 of these at once.
Q:Any good books on Fujian white crane kung fu? In particular their view on qi, jing, power and punching?
Yes, but they aren't any good.
Q:War is Kind by Stephen Crane?
War Is Kind Stephen Crane (1899) Do not weep, maiden, for war is kind, Because your lover threw wild hands toward the sky And the affrighted steed ran on alone, Do not weep. War is kind. Hoarse, booming drums of the regiment, Little souls who thirst for fight, These men were born to drill and die. The unexplained glory flies above them. Great is the battle-god, great, and his kingdom-- A field where a thousand corpses lie. Do not weep, babe, for war is kind. Because your father tumbles in the yellow trenches, Raged at his breast, gulped and died, Do not weep. War is kind. Swift blazing flag of the regiment, Eagle with crest of red and gold, These men were born to drill and die. Point for them the virtue of slaughter, Make plain to them the excellence of killing And a field where a thousand corpses lie. Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind!
Q:Do you know where Ty Crane is now? The one in the film coach carter?
Ty Crane is actually at Venice Beach in Los Angeles I just saw him, he was selling his mix tapes, we talked then he said he was Ty Crane the actor from Coach Carter. He smiled eveytime he said he was a movie star. Go to Venice beach by the weights and courts and you will see him there!!
Q:in the videogame the bully how do you get past the task where your in a pit with jonny and a magnetic crane?
sorry, i have finisheded the game but not sure which part you are talking about.
Q:I am a fellon, I made a mistake and I need help getting my crane certifacation. so I can work.?
lol, yeah, how about just flip my burgers.
Q:How do you jump a crane? I know you jack it up but how is that done?
I have no idea what you mean by jump a crane? What type of crane? Truck mounted, overhead, pedestal?
Q:how many different types of cranes and winches are there?
A bit more information might help. In England there are Winches and then there are winches. As for Cranes are we talking about birds.........actually there are only a few type of each.......but there can be quite a few variations of the basic types. let's say 6 types of cranes and 4 or 5 winches.
Q:The arm of a crane at a construction site is 12.1 m long, and it makes an angle of 30° with the horizontal.?
(a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N? τ = FL τ = 500(12.1cos30) τ = 5239.45 τ = 5240 Ν•m (b) What is the maximum load for this crane at an angle of 35° with the horizontal? τ = FL F = τ / L F = 5239.45 / 12.1cos35 F = 528.6109... F = 529 N I hope this helped. Please remember to vote a Best Answer from among your results. It's good karma as it keeps things in balanced exchange.
Q:Will Homeowners Insurance cover severe damage to driveway caused by crane?
Yes- it almost certainly will be covered. Most (if not all) homeowners policies provide coverage for driveways, walkways, etc. See your policy for specific language. I was an adjuster for 15 years, and I handled this sort of claim on a regular basis. It is very common for large vehicles to damage driveways, especially dump trucks. As long as there is sufficient evidence that the crane caused the damage (rather than normal wear and tear) it will almost certainly be covered. Your homeowners insurance will then subrogate against the tree removal company.
