Step 15 of 18: Configure Machine Beams and a Self-Constructed Gear Base

A2.15: Central Guided MRL

Written by Alexandra Göttert

Prerequisites

  • You can configure rope wall fixings.

Steps

Preparation: create the practice project

1.) Create and save the practice project. Using the Shaft Wizard, create a project with:

  • 5 floors, typical floor-to-floor distance 3000 mm

  • Consider travel: No; Create building floor levels: No

  • Traction elevator 2:1; 13 persons / 1000 kg, 1 m/s

  • Drive location in the shaft head (MRL)

  • Car roping 2 pulleys below, with CW safety gear

  • Counterweight roping 1 pulley top, counterweight left

  • Sheet templates: LD Installation Drawing and LD Typical Views For Your Elevator

  • Car width 1600 mm, car depth 1400 mm

  • Entrances front on all floors, rear on the first and last level

  • Pit 1200 mm, E1 2900 mm, E2 3000 mm, E3 3000 mm, E4 3800 mm

  • Save it as LDTrainingSampleA2_04.ld3.

Machine beams (central guided)

2.) Understand the default machine beams. For central guided MRL elevators, the machine and its machine bed are placed in the shaft head on two configurable support beams by default.

3.) Adjust the beams and their openings. Set the beam length and position, and adjust the corresponding wall openings separately, via the Properties docking window.

Gear base construction for self-construction

4.) Switch off the current support beams. The machine then sits directly on the machine room floor.

5.) Activate a gear base construction unit. Use the Properties docking window.

6.) Switch off unnecessary profiles. Customize the related product options.

7.) Arrange the Properties window. Close unnecessary functions for a more organized overview.

8.) Determine the beam dimensions and position.

Tip: Add a component-related annotation — it always refers to the reference point by default (see A3 – Drawing Creation Fundamentals).

9.)Determine the fixing settings. Set the fixings of the gear base construction.

Result

The default machine beams are adjusted or replaced by a self-constructed gear base, with unneeded profiles switched off, beam dimensions and position defined, and fixings set.
