Bespoke and special manufactured items of lifting equipment from SELS
We offer a professional design and manufacturing service for bespoke and 'one off' pieces of lifting equipment though are often requested to load test equipment manufactured by others with the intension of using it thereafter as a piece of lifting equipment.
We would be able to carry out the load test, however we would require from you a copy of the technical / quality file, drawing, calculations etc.. This would then allow us to issue both a ‘Report of Load Test' and a ‘Report of Thorough Examination of Lifting Equipment' in accordance with LOLER 98.
Please note that the capacity that you require the units load testing to must be detailed on the drawing and this is something for our customers to determine as they would officially be the manufacturer. As the manufacturer it would also be the customer's responsibility to write and publish the user manual, to CE mark the equipment and issue the EC declaration of conformity.
Without the calculations and drawing we would only be able to issue the ‘Report of Load Test' and this would only state that the equipment had been load tested on that particular day to the load requested - it would not allow for the equipment to be put into service as a piece of lifting equipment.
Our bespoke items of lifting equipment are more costly than similar standard products (or end user made items) though all bespoke items supplied by SELS must have a technical / quality file produced for the CE marking and the goods must be issues with an EC Declaration and a user manual; this creates unavoidable additional costs for design (drawing, calculations etc...), development, manufacturing, testing and commissioning.
We are committed to offering a professional service for the supply of quality bespoke manufactured items of lifting equipment, from concept to delivery. As you can now see it isn't quite as simple as just carrying out a load test on the items if you are using them for a lifting application.
Technical / quality file for bespoke / special manufactured items:
The technical file is the property of the manufacturer. All special / bespoke lifting equipment manufactured / supplied by SELS would be supplied with as “EC declaration of conformity” and “A Report of Thorough Examination” both in accordance with LOLER 98.
The technical / quality file (Technical Data Sheets), technical / design drawing and calculations are the property of the manufacturing company, we for our part do not send these to anyone; the reason is in the past we have sent this information on request from customers only to find they would use them to get other quotations or the unit manufactured in quantity elsewhere / overseas.
When we receive an order for special / bespoke items of lifting equipment we will send the client a general Arrangement (GA) drawing and general specification for approval. Production will not commence until approval is received and approximate lead times are agreed. We are members of the Lifting Equipment Engineers Association (LEEA) and work to our internal quality procedures in accordance ISO9001-2008 as audited by Moody International. Many of the Special manufactured products such as floor cranes are M-O-D and N-A-T-O approved, NCAGE Code U8235. All equipment is supplied complete with Letter of Conformity and Full Working Instruction.
IP Explanation and Ratings
EN 60529 outlines an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture. This classification system utilizes the letters "IP" ("Ingress Protection") followed by two or three digits. (A third digit is sometimes used. An "x" is used for one of the digits if there is only one class of protection; i.e. IPX4 which addresses moisture resistance only.)
Degrees of Protection - First Digit
The first digit of the IP code indicates the degree that persons are protected against contact with moving parts (other than smooth rotating shafts, etc.) and the degree that equipment is protected against solid foreign bodies intruding into an enclosure.
| First Digit | Description |
| 0 | No special protection |
| 1 | Protection from a large part of the body such as a hand (but no protection from deliberate access); from solid objects greater than 50mm in diameter. |
| 2 | Protection against fingers or other object not greater than 80mm in length and 12mm in diameter. |
| 3 | Protection from entry by tools, wires, etc., with a diameter of thickness greater than 1.0mm. |
| 4 | Protection from entry by solid objects with a diameter or thickness greater than 1.0mm |
| 5 | Protection from the amount of dust that would interfere with the operation of the equipment. |
| 6 | Dust tight. |
Degrees of Protection - Second Digit
The second digit indicates the degree of protection of the equipment inside the enclosure against the harmful entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.)
| Second Digit | Description |
| 0 | No special protection |
| 1 | Protection from dripping water. |
| 2 | Protection from vertically dripping water. |
| 3 | Protection from sprayed water. |
| 4 | Protection from splashed water. |
| 5 | Protection from water projected from a nozzle |
| 6 | Protection against heavy seas, or powerful jets of water. |
| 7 | Protection against immersion. |
| 8 | Protection against complete, continuous submersion in water |
Submersion depth and time must be specified by the end-user. The requirement must be more onerous than IP67
The IP Code Symbols
The chart at the right illustrates the use of special symbols in the IP classification system. In the "1st digit" column, not the grid-like symbols net to numbers 5 and 6. In the "2nd digit" column numbers 3-8 are symbolised by teardrop shaped symbols, sometimes enclosed in a box or a triangle, sometimes unenclosed (#7-8). These symbols can be placed on equipment to illustrate the IP protection provided.

| Note: EN 60529 does not specify sealing effectiveness against the following: mechanical damage of the equipment; the risk of explosions; certain types of moisture conditions, e.g. those that are produced by condensation; corrosive vapours; funus; vermin. | 7 |  |
