Article 5- Escalators and Moving Walks Transportation

Escalators and Moving Walks Transportation Technology

Nowadays, escalators and moving walks play a significant role in human life. It is almost impossible to imagine shopping malls, department stores, stadiums, subway stations, airports, and other public places where there is a massive number of people commuting, without escalators and moving walks existence.

Although the escalator and moving walk are huge mechanical machines, their transportation and installation must be done delicately. Faulty transportation can cause serious and irreparable damages to escalators and moving walks and people in the installation area as well. This process requires significant measures for secure and appropriate transportation of the escalator or moving walk.

Dos and Don’ts of Escalator and Moving Walk Transportation

There are tips for lifting the escalator or moving walk full assemblies or sub-assemblies which cannot be handled by hand based on EN115-2017. The tips are mentioned in the following:

a) Either be equipped with fittings for movement by a lifting device or transportation means, or

b) Be designed in a way that such fittings can be attached (e.g. threaded holes), or

c) Be shaped in a way that the lifting device or transportation means can be attached to it easily.

Note that the escalator or moving walk truss comes in a chassis form and it must be lifted from the points that are calculated during its design. There are usually points designed in the escalator or moving walk to facilitate the attachment of towing wires to the machine. Lifting the escalator or moving walk from the unauthorized points and directions would contort the machine irreparably or causes defects to its performance.

Different types of cranes and devices are used for lifting the escalators and moving walks in different situations. Types of the cranes and devices used in this respect are as below:

  1. Ceiling cranes for transportation at factories or garages
  2. Crane trucks for loading and unloading purposes
  3. Forklift trucks for lifting
  4. Tower cranes for unloading and installation
  5. In-plant cranes for lifting purposes
  6. Manual chain hoists for installation
  7. Aluminum gantries for installation
  8. Coupling devices for towing the escalator or moving walk
  9. Escalator saddle support for lifting the escalator or moving walk off the ground

The above-mentioned transportation devices are mostly used when there are space restrictions or when the ceiling is of a low load-bearing type. When escalators or moving walk are to be delivered in a close destination and their transportation doesn’t need to be done by containers, they are usually ordered fully assembled in one part. when escalators and moving walks are supposed to be delivered to the destination using a container or in case the escalator/moving walk is long or space conditions of the project are limited, they walk can be delivered in two or more parts.

Escalators and Moving Walks Transportation is possible in different ways; by land or railways, by sea, or airways. Since transporting them by airways is costly, they are usually transported by land (when the destination is close), or if there is a waterway by sea, or by a combination of two of them.

If the delivery destination of the escalator or moving walk is close, there is no need to transport them using a container and they will be delivered in full-assembled forms as usual.

When the escalator or moving walk is supposed to be transported by a container e.g. transporting by sea, or when the escalator is too long, or there are space limitations in the project area, they must be constructed in two or more parts. In this case, the escalator truss is constructed in a few parts and therefore, the parts will be assembled by socket-headed bolts attaching to the pre-drilled points on the plates based on the standard. Also, Balustrades and handrails will be delivered in separate pallets to the destination and the final installation process will be done after mounting the truss in the installation area.

During the construction and delivery preparations, some of the steps are not installed at the joint sections, and the step chain is hampered with fasteners. Then, the step chain will be assembled again after coupling and will create a ring.

Note: If the escalator or moving walk lengthy and does not fit the container, the parts will be placed on each other, with certain spacers to prevent their contact with each other, in the container.

Given all the information above, it should be noted that delivering the escalator or moving walk in separate parts is inevitable. Therefore, the delivery type must be specified before manufacturing. Besides, when transporting the escalators, the transportation route must be safe and without any object hindering the route. When choosing a transportation route, route safety must be prioritized.
