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 is tower crane? What are the types and features?
According to the movement can be divided into: walking type and fixed type. The fixed tower crane tower body can not be fixed, installed on the whole concrete foundation, or installed on the strip or X concrete foundation, and the walking type can be divided into four types: caterpillar type, automobile type, tyre type and track type. In the construction of housing, the general use of fixed type. It can be divided into two kinds of horizontal boom, luffing and luffing of luffing arm according to its variable amplitude. According to its installation form, it can be divided into three kinds: self lifting, integral quick dismounting and assembling. The most widely used are down slewing, rapid dismounting, track type tower cranes and self elevating tower cranes which can be used with four machines (track type, fixed type, attached type and internal climbing type).
Q:What are the main technical parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
Q:What are the safety devices for tower cranes?
(6) the rail clamp is used to clamp the rail, prevent the crane from walking by wind in the strong wind, and cause the tower crane to derail and overturn the accident.(7) the wind meter automatically records the wind speed, and automatically alarms when more than six wind speed is over.(8) the anti stripping device of the steel wire rope is mainly used to prevent the steel wire rope from disengaging from the pulley groove during the transmission process(9) the hook insurance prevents the lifting of the steel wire rope because of the excessive angle or the wrong hook, and causes the lifting wire rope to be broken off and the suspension falling accident.
Q:What kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
The car must have a support wheel to prevent the trolley from hanging in the middle.
Q:[tower crane] and [tower crane] what is the difference between, how to distinguish?
There are many nicknames for tower cranesTower Crane Tower Crane Tower
Q:What is the calibration value of a tower crane?
Three, gravity moment MThe product of amplitude L and the corresponding lifting objects called Q gravity lifting moment, the unit is kN - M.Tower crane capacity is based on lifting moment representation. It uses the product of the maximum working range and the corresponding maximum lifting load as the calibration value of the lifting moment.Four 、 lifting height HIt refers to the vertical distance from the surface to the parking level of the crane sling allows the highest position. The unit is m.Five, work speed1. lifting speed (down) Vn - stable state of motion, the vertical displacement velocity of the rated load. The unit is m/min.2. crane (CART) running speed of Vk, stable state of motion, the running speed of the crane. The operating speed of a crane with rated load on the horizontal (or horizontal rail) surface, at the height of 10m away from the ground, and when the wind speed is less than 3m/s.
Q:What kind of tower cranes are available? How about the scope of all kinds of tower cranes?
Tower crane is divided into fixed tower crane, mobile tower crane, jack up tower craneThe mobile tower crane is divided into track type, tire type and automobile typeThe jack up tower crane is divided into two parts: internal climbing type and attached typeUsage: loading and unloading concrete by hanging tank for general construction and installation
Q:What does tower crane jacking up mean?
First of all, the boom and trim balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.Jiangsu Zhendong port machinery manufacturing heavy port machinery is a professional manufacturer of mechanism
Q:What is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:
