Product Description:

55RCS25 Series Hoisting Mechanism

Introduction

Such production are independently developed and manufactured by our company based on mature technologies of French Potain Company with rated hoisting weight of 8t,10t,12t and 16t.Horizontal and vertical motor mounting types and different rope capacity are available for users. Such products adopt two winding 3-phase asynchronous motors and series excitation speed regulation circuit which realize interactive effects via gear assembly to constitute speed regulating system with features of wide range of speed regulation, high-speeding hoisting, low-speed positioning, stable speed change and high working efficiency. The mechanism adopts L-shap in overall layout and employs winding drum of Lebus grooves with large rope capacity, which can prevent disorder in case of multilayer winding of wirerope and satisfy wide use demands of high-rise building construction, hoisting of large equipment & construction member, etc.

Q:What are the parts of a tower crane? What are their main functions?
Jacking frame: placing slewing mechanism, when lifting tower top, bearing the weight of tower crane balance arm, main arm and tower cap.Standard section: support the weight of tower crane itself and lift the weight of heavy load, and resist the overturning moment of tower crane.Institutions include the followingLifting mechanism: lifting heavy objects.Luffing mechanism: lifting the car to change the rotation center distance.: the upper part of the slewing mechanism of tower crane (including the main arm and balance arm and tower cap) around the rotation center of rotation.Lifting mechanism: tower crane lifting, the upper part of the tower crane elevated hydraulic power system.Walking mechanism: the crane can walk on the track.OtherDrivers’ RoomElectric boxLinkage tableA foundation bearing platform or trackOther safety devices
Q:Protective earthing resistance of tower crane
Q:Why do tower cranes need to be fabricated?
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure light steel wire rope (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is bonderizing, can solve the wear problems of wire rope used in the process, according to the current market situation of wire rope, manganese phosphating coating of steel wire rope price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase, so the phosphating coating steel wire rope daily use fee is only plain steel wire 30-45% rope, the use of lower cost, higher cost, smooth steel wire rope is eliminated. For reference only
Q:What are the construction cranes? 50
Tower crane, crane, man goods elevator, lift, there are national standards
Q:How to calculate the pouring and maintenance of tower crane concrete in valuation?
Valuation, tower crane concrete foundation pouring and maintenance costs are included in the tower crane rental costs, not separately assessed.
Q:What are the types of common tower cranes?
(3) according to erection methodNon self erecting tower crane: a tower crane assembled and erected by other lifting equipment.Self erecting tower crane: a tower crane that relies on its own power unit and mechanism to realize the transition between the transportation state and the working state.(4) according to variable amplitude methodThe trolley jib tower crane lifting trolley along the tower crane luffing boom for operation.Boom luffing tower crane: luffing tower luffing luffing luffing crane.Folding tower crane: tower crane which can be bent by boom according to the needs of lifting operation. It can also have the performance of luffing and luffing.
Q:Construction tower crane driver (T) Ben can be used as construction crane driver (S)?
Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.
Q:Minimum QTZ63 tower crane special electric box open for many A
Minimum QTZ63 tower crane special electric box for 100A circuit breaker. The maximum lifting weight is: 6T; lifting torque: 63kN; m; tower crane lifting height is 40m (independent), 140m (attachment); power: 31.7 kW; work range: 2---57m.
Q:Lifting tower crane tower more than 45 meters, the demolition cost and how to adjust the field Sinotrans transportation fees?
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
Q:QTZ63 (Q5610) tower crane power, how many power parts, name, model specification, product number, date of appearance
All the details of the equipment are availableAs for power, it depends on the specific configuration of the frequency conversion and non frequency conversion will not be the same
