A Project Crane is a dedicated crane for all kinds of project construction. The most commonly seen project crane is Gantry Crane. A project gantry crane can be used for road, bridge construction, metro construction, shipbuilding, tunnel construction, power plant construction and other project construction.
The gantry structure can be box type girder and truss type girder with light weight, small wheel pressure and reliable performance. Project crane is mainly made of steel splicing, which can be Single Girder Gantry Crane and Double Girder Gantry Crane. The hoisting mechanism cane be a hoist or a hoisting trolley. The lifting and running speed are slow, and the cost is low, which is suitable for construction.
Capacity: 10t - 800t or custom
Span: 6m - 32m or custom
Lift height: 6m - 32m or custom
Working duty: A5, A6, A7 or custom
Sling device: hook or special project slings
Packing: wooden case, rain cloth, reinforced bar, etc.

Product Name: Single-cold type electric air-conditioning
Product Characteristics:
--Energy conservation:
1.The manner of soft triggering frequency conversion has been adopted,so the triggering
operation is stable, the triggering current is gradually transformed into operation
current, avoiding the waste of energy brought about by impulse current.
2.when the setting temperature is reached,the air-conditioning can keep the car's inner
temperature with lower frequency and smaller power, and frequent enablement is avoided.
3. Adopt frequency hermetic scroll compressor whose volume efficiency is more efficient
than the traditional piston compressor by over 30percent.
4. Heat exchanger choose corrugated fin, internal thread copper tube to increase the
heat exchange area and improve the transfer efficiency.
5. Single-cold type air-conditioning adopting Micro-channel heat exchanger technology,
reducing the condensing wind resistance and improving the transfer efficiency, reducing
the refrigerant of the filling quantity.
6,Heating type Air-conditioning adopting heat pump heating, compared with the way of
electric heating or fuel heating, energy-saving effect is remarkable.
7,Install overhead unit air conditioning unit, have no use for field installation
connection line, the vacuum and filling refrigerant, field installation workload and
installation time has reduced.
8,By means of the inner structure was optimally designed,use a series of lightweight
measures , such as Micro-channel heat exchanger and DC brushless fan, and the weight
of the Single-cold type air-conditioning was only 305 kg.
--Comfortable:
1,Advanced active adaptive vector conversion technology has been adopted. After air
conditioning engine on, with high frequency operation, it outputs a refrigerating
capacity of the largest (system heat), achieve setting temperature quickly,and then
according to automatic adjust operation frequency and output power of internal thermal
load, it makes the inside temperature always in a relatively stable state, the human
body feel comfortable.
2,Noise reduction measures are taken, such as multi-stage vibration absorber,
optimization of air volume matching, uses heat preservation material has sound
-absorbing effect, reduce the vehicle noise maximum.
--Dependable:
1,International famous brand parts was adopted, laid the foundation for the high
quality of products.
2,Fully enclosed scroll compressor was adopted to avoid the leakage problem about
open piston compressor.
3,Dc brushless fan or ac frequency conversion fan has been adopted, service life is
better than a brush fan.
4,Overhead unit, single system, integrated modular and less parts structure has been
adopted, reduce the fault point.
5,All welded system line has been adopted, to avoid the leakage problem about thread
connection.
--Safety:
1,Strictly follow safety indicators such as the GB/T18384.3 safety requirements of
electric car part 3: personnel get an electric shock protection ", "CJ/T5007 trolley
bus technical conditions", "CJ/T5008 trolleybus acceptance method".
2,Strengthen level insulation, high and low voltage isolation, open cover cut high
pressure and other security measures have been adopted, to eliminate hidden trouble
about personnel get an electric shock.
3,We have electric protection function such as over voltage protection, under-voltage
protection, over current protection, open phase protection, etc.
4,We have system protection function such as high pressure protection, low pressure
protection, exhaust temperature protection, etc.
5,We have a counter-attack joint function, to ensure that under the situation of the
dc high voltage source pick back not damage the equipment.
