Low-speed lift

Mobile platforms are construction machines such as cranes used to move people and materials to a specific workplace, both vertically and horizontally. In the colloquial language, there are also the names "basket" and "increase"


The use of mobile platforms takes place primarily in such industries as the construction, service and industry sectors. It depends primarily on their design. They are widely used in all work at heights, incl. for: cleaning windows, glazing and facades of buildings, trimming and cutting trees and shrubs, for work on power lines, in assembly and renovation works on construction sites, in warehouse works, in the broadly understood industry, and even marketing! (for mounting graphics on billboards)

Scissor basket

Design elements

The basic and essentially invariable components of a boom lift are the basket/gondola and the platform responsible for the movement. Depending on the type of lift, this may be a crane or a linkage. In addition to these, there are a whole host of components specific to particular categories of machine, as discussed below.

Classification by types

  • Hanging platforms - an interesting example. Commonly used, for example, by teams cleaning windows in skyscrapers. They mainly consist of:
  • the load-bearing structure of the platform
  • the work platform
  • lifting ropes and safety lines
  • winches

And besides, also:

  • catch apparatus
  • friction winch
  • the running wheel of the work platform
  • hanger
  • railing handrail
  • railing crossbars
  • curb
  • floor
  • vertical railing post
  • bumper rollers

Depending on the intended use, these platforms can either be permanently mounted to a specific building (e.g. in a
renovation purposes) or temporarily on special construction rails. The work platform is attached to the suspension cable by means of a hanger, and may have one attachment point (single-point suspension) or several (two-point, multi-point suspension). The biggest advantage of this technical solution is that it is easy to transport and assemble, while the biggest disadvantage is its susceptibility to external influences, particularly wind.

The entire mast platform consists of: the working platform, the mast / masts on which the former moves and the base (chassis) on which the mast rests, the drive mechanism used to move the working platform.

The main advantage of this format lies in its compact design, perfect for operating in narrow spaces, unfortunately this is at the expense of a relatively short reach. This is why mast platforms have found widespread use especially in warehouses, archives and sorting rooms.

  • Low-speed platforms

As the name suggests, they are distinguished above all by the drive they have (diesel or electric).Taking into account the type of superstructure that supports the working platform, we can divide free-running platforms into:

  • scissor lifts - folding and unfolding the scissor mechanism allows the work platform to move vertically
  • telescopic platforms - the supporting structure is in the form of a telescopic mast
  • articulated platforms - the supporting structure is in the form of an articulated mast
  • telescopic articulated platforms
  • loading platforms / tailboards

These are platforms attached to the rear of vans (up to 750 kg capacity) or trucks (up to 1,500 kg capacity), usually hydraulically powered. They are used to lift a load for loading or unloading. When fitted to a vehicle, the lift becomes an integral part of the vehicle.

Necessary permissions

Mobile platforms, like most tools and construction aids, are subject to the supervision of the Office of Technical Inspection. This authority also issues appropriate powers on the basis ofRegulation of the Council of Ministers of December 7, 2012 on types of technical devices subject to technical inspection (Journal of Laws of 2012, No. 0, item 1468), issued pursuant to Art. 5 sec. 2 of the Act on technical inspection and rRegulation of the Minister of Entrepreneurship and Technology of October 30, 2018 on technical conditions of technical supervision in the field of operation, repair and modernization of handling equipment (Journal of Laws 2018, item 2176).
