Detailed introduction to NH Model Electrical Hoist:
The NH series electric hoist adopts Demag's advanced electric hoist
design.
Electric hoist lifting mechanism uses planetary gear, its structure
is compact, lightweight.
The mechanism is installed in the reel, whcih reduces electric
hoist dimensions.
Electric hoist designe maximizes the modular design, a
high degree of component commonality The shell structure is with a
square design, electric hoist up and down around the four
directions of the design of the installation location.
It can be used as a ltrolley. The design criterion used by
the European FEM standards, easy to maintain.
High efficiency and high convenience.
Brief Introduction to Quality Control:
A complete quality control system has been set up to
guar antee that all products of the company comply with national
technical standards.
Ⅰ.Sound quality control machanism
Quality management and quality
test departments are staffed with engineers,technicians and
inspectors,who are responsible for quality management,test and
information feedback of products of the company.
A quality control test system has been
set up to conduct self test,mutual test and inspector test for each
spare part,unit and between producing procedures.Rates of qualified
products,waste products needing repair are checked to relate the
rates with workers' economic benefits so as to guarantee quality of
spare parts and units.
Ⅱ.Reliable guarantee by establishment of
physical lab,chemical lab,measuring room,whole-machine test
platform.
1.Physical lab
The lab is equipped with metallographic phase analyzer,X-way
nondestructive tester,metallographic microscope,hardness tester and
professional staff to guarantee effective quality inspection of
heat processing,soldering,material and spare part bought from
outside.
2.Chemical lab
This lab is equipped with WFJ-P digital
spectrophotometer,TG328A electro-optical analysis scale(precision
reaching 1/10000 gram),CS-TL4B carbon flow tester and professional
staff to conduct effective chemical analysis over raw materials and
spare parts from outside.
3.Measuring room
Staffed with professionals,the room has over 300 measuring
devices.For important spare parts like gears of decelerator
box,there are devices like deflector tester and tooth gauge to
guarantee quality of those spare parts.In addition,testers for
electric hoist,traveling crane,gantry (bridge)crane are
available,such as theodolite,level and portable hardness gauge.
4.Whole-machine tester
The test platform for performance of whole traveling
crane and the computer-aided test platform for performance of electric hoist have been set up to provide data critical for the performance
of the machines.The following tests can be conducted:①Empty-load
test②Still-load test(including 25% overload test)③Dynamic
test④Rated load test
In summary ,our company has set up a complete quality
control system with basic complete devices to guarantee product
quality.
