I need to finish a task of electrical component purchase order list of a hoist package. First, I have to search the project profile to check what is the type of hoist.
Hoist Type : SWL 5 Ton STAHL SH5025-20 2/1 L2
9.0/1.5kW Hoisting motor
0.55/0.12kW Cross Travelling motor
From the data above, I have to search the nominal current ratings from the catalogue in order to pick only necessary and suitable electronic and electrical to be installing in the hoist control box.
Complete Hoist Control Box
The SLE 21 load monitor is already provided by STALH company.
This my first time to learn about function of contactor and its usage. The contactor of Telemecanique brand that I have select according to power ratings.
Timer Block LAD-TO and LAD-RO.

METALTECH 2010 at PWTC
08/05/10, Saturday - After half-day work, I follow my Electrical Department Manager and colleague go to visit METALTECH 2010 at PWTC, a exhibition of metal tool, metalworking machine and robotic equipment. This a really special event for me to open my eye in today's high technology factory equipments that I never see and tough it before. There are many oversea exhibitors such as Singapore, Korea, Taiwan, German, India, China and others.
Even though the theme title is METALTECH, but these event show a lots of machine and robotic that involving electrical and software design. Some of the machines need programing to run it for the precision manufacturing process.
My visitor pass with the name of company
There are 5 hall in the exhibition event.

Choosing the conductor bars for crane system
The Main Supplier of the conductor bars for our company are Conductix Wampfler(a Germany Company) and IGA (Spain Company). I need to learn and know more about these product before I starting with my calculation of voltage drop, in order to choose the most suitable conductor bars. The manager want me to focus on Wampfler Single Powerline 0813 and LM-4 of IGA.
Wampfler Single PowerLine 0813

Nominal Current [A]: 200 - 1250
Nom. Voltage [V]: 690 (1000 V with add. insulators)
Support Spacing [m]: 2,5
Standard application data
- Nominal Current (at 100% duty cycle) [A]: 200 | 320 | 500 | 800| 1.000 | 1.250
- Voltage Grade [V]: 690
- Rail Length [mm]: 5.000
- Outside-Dimensions (Pol) [mm]: 32,0 x 42,0
- Operating Conditions: for indoor and weather protected outdoor applications
- Track Configuration: preferably for straight courses / curve segments available
Special features
- High availability in strong industrial environment trough several material
- High level of safety trough insulation profiles with integrated finger safe protection
- Easy and exact mounting with multiple hanger clamps for (3, 4 and 5 pol)
- Free and unlimited combination for multiple amount of rails
- Radius segments for curves available
Main applications
Process and EOT(Electrical Overhead Travelling) cranes
People Mover
Container Cranes
--------------------------------------------------------------------------------
IGA LM-4
Mobile power supply feeding point along the IGA conductor in the factory
Channelling electrical protection with the use of current displacement. Applicable for security, like mobile electric power supply with fixed paths (straight or curved) on crane, hoist, moving electrical machinery, moving equipment and in general, wherever it is necessary to have mobile power.
Find the Nominal Current of those motors in cranes system
Determine Voltage Drops and Choose L feed-in
The Voltage Drop should be less than 2.5%

SEE Electrical drawing software product of Siemens
Most of my time in 4th week was doing the Electrical circuit drawing using the SEE electrical software that company brought from E-solid SDN BHD with the price of about RM 5000 per each license.
Firstly, I studied the manual for two day. I had a chance to try myself to use the software at a senior electrical engineer desk-top because he went for outstation in China. Below is some of the part manual of SEE software.
From Wednesday to Friday, I started 4 electrical circuit drawing that my manager given to me to design. There are three different type of 5 ton Electrical Overhead Travelling Crane for the customer in Penang, which is TEIK HOOI ENGINEERING SDN BHD and one 10 ton Electrical Overhead Travelling Crane for IMO (INDUSTRIAL MATERIALS ORGANIZATION (L.L.C) Industrial, Hydraulic, Electric Tools & Equipments), a project in Suadi Arabia.
