Product Description:

General

Electrical Single-girder Gantry Crane is used together with CD MD Model electrical hoists.

It is a track travelling small and medium-sized crane.

Its proper lifting weight is 5 to 10 tons, proper span is 12 to 30 meters, its proper working temperature is

-25°C to 40°C

It has two controlling methods, namely ground controlling and room controlling.

Feature

1)Power source is three-phase alternating current,rated frequency is 50Hz, rated Voltage is 380V.

2)The altitude height of site is ought to be less than 2000M.

3)Flammable,explosive and corrosive gas are forbidden in the work environment.

4)The crane is forbidden to lift fuse and blend deleterious article and flammable explosive article.

Technical characteristics

This crane has hard surface gear reducer and steel rope and three-in-one transmission mechanism.

Protective functions are as the following:

1)Acoustic-optic alarm, hook automatic stop protector, circuit protector and over current and

phase lose protection and intelligent limit.

2)The electric devices adjust speed without contactor spark module and fulfill frequency convert function to

reach mini-speed and double speeds, which make travelling and lifting very steady.

3)The operating board (handle) adopts 12V safe voltage.

4)The electronic controlling can be used more than 2 million times when the voltage is +5~-10% of 380V.

Choosing principle of  single gantry crane

According to the working system and using field. Which system you will choose, field should go first.

Calculating the times per hour of starting and pulling-on recycle,you should make the practical time per day

and continuous time

When select or appraise, you should be sure such items as field, all the limiting size, ambient temperature,

speed, time(h), intermission or continuous, the time of starting and pulling-on per hour, etc.

The above mentioned is just for reference. Reasonable selection, design and match can increase the working efficiency greatly.

Q:What is the main girder of the gantry crane?
Compared with the double girder gantry crane, the overall stiffness is weaker.Therefore, when the weight Q ≤ 50t, span S ≤ 35m, can be used in this form.
Q:Truss and "Hang Hang" are two concepts?
In the port, mainly for outdoor freight yard, yard cargo, bulk cargo loading and unloading operations.
Q:What are the technical parameters of the gantry crane?
, Counted to the bottom of the container.The span is the horizontal distance between the centerline of the gantry running track, in m
Q:What is the gantry crane gantry?
The use of steel welded into a box structure, with high security, high stiffness and so on.
Q:Do you want to retire early?
Countries have special types of work can be found.Special types of work refers to the category of special operations personnel in the general category, refers to the occurrence of casualties accidents, the operation of others, others and the safety of the surrounding facilities have a significant harm to the type of work.
Q:Gantry crane when the load when the crane parked in what position?
When the gantry crane stops, first put the controller in the space, disconnect the power, lock the door of the cab, to the door
Q:Gantry crane does not hang what things?
Command signal is unknown or chaos command is not hanging;More than the rated weight when not hanging;
Q:Can the span of the gantry be customized?
At present, ship cranes, container yard and other cranes are divided into two types, namely, rail container cranes (RMG) and tire container cranes (RTG).
Q:What is the similarities and differences between bridge cranes and gantry cranes?
The bridge of the bridge crane runs longitudinally along the rails on both sides of the viaduct, making full use of the space below the bridge to lift the material from the ground equipment.
Q:Gantry crane is not a tower crane?
Applicable to station terminals, warehouse freight yard, construction site, cement products field, factories, hydropower stations and other open-air workplace, but also for indoor workshop work.
