Product Description:

Introduction

On the basis of absorbing advanced foreign technology, our company developed the JXD trolley luffing mechanism independently for small and medium-sized tower cranes.

This series of trolley mechanism consists of electromagnetic double-speed change-pole motor, semi-concealed planetary reducer, drum, frame and other components.Its characteristics include compact sturcture, high driving efficiency, and low noise, safe and reliable braking, accurate positioning, pleasing in appearance and so on. When users have higher requirements to the trolley running, variable- frequency speed regulation motor with the same interface and relevant electric contol system may be changed to form the variable-frenquency speed regulation trolley mechanism.

Q:Calculate the tower crane gantry crane
It's a gantry crane, not a tower crane
Q:What is the minimum radius of a tower crane?
The higher the rise, the larger the angle, the smaller the radius.I wonder if it's this angle? Hope to be of help to you,
Q:What are the types of tower cranes?
The tower crane is divided into: fixed tower crane mobile tower crane self lifting tower crane mobile tower crane is divided into: rail type tire type automobile type self lifting tower crane is divided into: attachment type climbing uses: concrete with cage for loading and unloading installation general building mixed
Q:Protective earthing resistance of tower crane
Q:Emergency treatment of interrupted electricity during lifting of tower crane
The rotating gear shall be immediately inserted into the screw or wood, while the power supply shall be checked rapidly to remove the trouble.
Q:What are the four major moving mechanisms of a tower crane?
The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking.There are many types of tower crane, if according to whether the walking mechanism, there is a fixed type and operation type; according to the tower structure is divided into rotary, inferior type, attached itself three; if divided by the amplitude, a trolley type, luffing type and folding arm luffing type three; according to the weight division, with light and medium and heavy three.
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
The name of QTZ is the former mechanical standard, Q refers to the crane, T refers to the tower, Z is to indicate the self lifting, and the latter figure represents the nominal torque, the unit is T.M (the standard unit is KN.m)The type of "QTZ63" indicates the hoisting tower crane with nominal lifting torque up to 630KN.m;The type of "QTZ80" indicates the hoisting tower crane with nominal lifting torque up to 800KN.m;
Q:What are the necessary safety devices on a tower crane?
(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.
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:Under what circumstances does a tower crane require third party testing?
New clothes, relocation or transformation should be examined by the quality and Technical Supervision Bureau
