Description

  • The invention relates to a method of manufactoring any one model selected from among a plurality of models forming a range of work platform products, wherein each model embodies a trailer-mounted arial work platform, which is easier to manufacture than earlier solutions, and the construction of which can be more easily modified during manufacture for different models. The trailer mounted aerial work platform can be manufactured for many different hoisting purposes.
  • Trailer mounted aerial work platforms are generally used for any kind of work where the person carrying out the work must be raised to a higher working level than normally, see, for example, EP-A-0 732 300, which is the most relevant state of the art. Work like this includes painting, washing windows, and various building and installation work, among others. Trailer mounted aerial work platforms are generally manufactured for maximum working heights of about 10 to 25 metres.
  • The aerial work platform should be designed to allow the hoist to be easily moved from place to place by towing. For this reason, the construction of the base of the passenger hoist must meet certain requirements. The base must naturally be steady enough during lifting, but as light as possible when towed. The size of the base should also allow it to pass through narrow places when towed.
  • The trailer mounted aerial work platform is manufactured with either a telescopic boom construction or an articulating telescopic boom construction. A trailer mounted aerial work platform with a telescopic boom is of simple construction and it is often used in construction and installation work. An aerial work platform of telescopic boom construction has an adjustable telescopic boom. The working height to be used is determined by the length of the telescopic boom.
  • A trailer mounted aerial work platform of articulating telescopic boom construction differs from a platform of telescopic boom construction in that it also comprises articulated arms. The construction of a passenger hoist with an articulating telescopic boom enables vertical movement of the cage. An aerial work platform of articulating telescopic boom construction also has an adjustable telescopic boom. The working height to be used is determined by the length of the telescopic boom together with the position of the articulated arms.
  • In an aerial work platform of articulating telescopic boom construction, the articulated arms make up a part of the lifting height, whereby the length of the telescopic boom can be reduced. Therefore an aerial work platform with articulating telescopic boom construction can be made shorter than a platform of telescopic boom construction which can reach a similar height.
  • In prior art trailer mounted aerial work platforms, the individual construction has been a problem with regard to manufacture. Because aerial work platforms have often had different requirements of use, many different sizes and models have been manufactured. Aerial work platforms have been manufactured in small series, and the planning, testing and manufacture of each size and model has been carried out separately. This has brought about the need for a new kind of a product series of trailer mounted aerial work platforms, which is easier to manufacture than earlier platform solutions, and which is constructed of a smaller number of different parts.
  • It is the object of the present invention to provide a method of manufactoring any one model selected from among a plurality of models forming a range of work platform products, wherein each model embodies a trailer-mounted arial work platform by which the above mentioned problems can be solved and the defects corrected. In order to achieve this, the trailer mounted aerial work platform is characterized in that the aerial work platform is implemented as a modular construction, which comprises a boom construction and a base construction, combined with a turning device construction of the desired type.
  • The trailer mounted aerial work platform thus consists of modules. The platform construction according to the invention comprises a boom module and a base module, which are combined with a slew device module of the desired type.
  • In the following, the invention will be described in more detail with reference to the accompanying drawings, of which
    • Figure 1
    shows the trailer mounted aerial work platform according to the invention with telescopic boom construction,
    Figure 2
    shows the trailer mounted aerial work platform according to the invention with articulating telescopic boom construction,
  • In Figure 1, the trailer mounted aerial work platform is implemented with telescopic boom construction. The trailer mounted aerial work platform of telescopic boom construction comprises a boom module 3 and a base module 1, which are combined with a slew device 2. A cage module 4 is attached to the boom module 3. The base module 1 comprises wheels 5, 6 and stabilizers 7. The cage module 4 is raised to the intended point of operation by means of hydraulics 8, 9.
  • In Figure 2, the trailer mounted aerial work platform is implemented with articulating telescopic boom construction. The trailer mounted aerial work platform of articulating telescopic boom construction comprises a boom module 3 and a base module 1, which are combined with a slew device 11 and articulated arms 10. A cage module 4 is attached to the boom module 3. The base module 1 comprises wheels 5, 6 and stabilizers 7. The cage module 4 is raised to the intended point of operation by means of hydraulics 8, 12, 13.
  • The trailer mounted aerial work platforms is implemented as a modular construction so that a base module 1 of the same size class can be used both in hoists of articulating telescopic boom construction and in hoists of articulating telescopic boom construction reaching the same hoisting height. Correspondingly, a boom construction 3 of a certain size class used in hoists of telescopic boom construction can also be used in hoists of articulating telescopic boom construction reaching the next hoisting height.
  • Trailer mounted aerial work platforms can be manufactured for maximum working heights of approx. 7 to 35 metres. The new kind of a product series of trailer mounted aerial work platforms is easier to manufacture than the earlier solutions. The construction of the aerial work platform enables easier manufacture of the desired platform model. The trailer mounted aerial work platform can be manufactured for many different lifting purposes.
