Invermóvil Print E-mail

Construction of the greenhouse roof structure at ground level and subsequent erection of the tunnels with the help of motor-driven reduction gear systems.

The Invermóvil consists of a new construction procedure by means of which the risks of working at height are avoided to a great extent, as most of the structure of the greenhouse is mounted at ground level and then lifted into its definitive position making use of motor-driven reduction gear systems.

The improvements sought in this project are based fundamentally on reducing the hours that the operative is working at height, but keeping in mind that the costs of the new system must not be excessively high so that the product can be competitive in the marketplace.


Characteristics:
  • Redesign of the column head whereby it is divided in two independent parts, which can be joined later at the elevation of the adjoining tunnels, so that the tunnels can be erected independently of each other.
  • Placement of the lifting motor at the base of the column, for which it is necessary to have a large plate fixed to the ground by means of a welded tube with plate and journal with internal bearings.

 

Components:

  • Electric motor
  • Support of motors fixation to pillar
  • Pulleys
  • Split column
  • New column bands
  • Bearing block for drive tube
  • Winch head
  • Plate
  • Anchorages of moving parts
  • Electric system for motors
  • Control system for motor operation
  • Traction cables
  • Chanelling
  • S-Hook
  • Tensor

 

 

 

Benefits:

  • Greenhouse with dimensions and characteristics similar to those that are presently on the market, but with improved occupational safety for the operatives.
  • Enhanced competitiveness.
  • Reduction of 40% in working hours at height, which in itself justifies the application of this new construction system.
  • It can signify a 15% cut in manpower requirements in the case of tradesmen and 8% in the case of labourers.
  • The need for lifting platforms is decreased by almost a half, and can mean a saving of 45% in this type of machinery.
  • This type of greenhouse means a reduction of more than 10% in the assembly time, using the same gangs of operatives in the two systems compared.
