Weihua Electric Hoist, handling heavy materials. Sales volume No.2
in Chinese marketing. CD model is single speed, MD is double speed,
which can do precise operation. CDI MDI type wire-rope electric
hoist is akind of light-small lifting equipment with advantages of tightstructure, light weight, small volume,
wide common use and convenientoperation etc.If reducers with hard
gear surface are applied, it willhave long life and high mechanical
efficiency. Conic rotor brake motorsare equipped which has safety
limiter in both up and down directions. MDItype electric hoists
have fast and slow lifting speeds which make it lift steadily and
accurately. CDI MDI type wire-rope electric hoists canbe widely used to hoist heavy objects, or installed on the straight orcurve I-steel beam
of Single-girder Cranes. They can also be usedtogether with Electric Hoist Double-girder, gantry crane and slewingcranes. All the above has made the electric hoists
common in industrialand ore enterprises, railway, wharfs and
warehouses.
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
