Changing of Sleepers

Many people may have come across the huge gantry cranes standing in the midst of the trail along the way of East – West Line (EWL) between Chinese garden & Lakeside stations and North South Line (NSL) at Pasir Ris station. These two Jenmon fixed gantry cranes are deployed to speed up the works along the tracks, which include the replacement of rail sleepers.

As this project is the first of its kind in Singapore, it is considered quite new. Having been awarded to Gammon Construction Pte Ltd, a subsidiary company of Gammon, this firm mainly contributes to Singapore's infrastructure including the completion of many contracts for the Land Transport Authority (LTA), as well as several major projects in the commercial and petrochemical sectors.

Jenmon had been appointed by Main Contractor Gammon Construction to install two units of Fixed Gantry cranes for a replacement of the sleepers. These two fixed gantry cranes installed with various safety devices were used to hoist the Road Rail Vehicles (RRV) lifting system and Concrete sleepers for the replacement of the current wooden sleepers. Deploying more effectively solution to the work front and thus allowing more sleepers to be replaced. Contrariwise, using conventional mobile cranes and long set up time would be costly and impossible.

Prior to the selection of fixed gantry cranes, Jenmon's team brainstormed the various design options with the customer. Having the knowledge of the customer's needs and constraints, such as the short working duration of three hours in the early mornings, so as to not disrupt the train operation during the day, Jenmon fixed gantry cranes was able to come to fruition. Made of steel structure, Jenmon's fixed gantry cranes were able to accelerate the task on hand. Hence, also ensuring the stability and durability compared to other large and heavy machines, such as mobile cranes.

Specifically, a gantry crane is a great alternative to the mobile crane. A gantry crane has a lifting capacity of up to 15 tonnes. Furthermore, to hoist the RRV lifting system, the two legs of the gantry crane ensures balance and stability in enduring heavy loads.

We believe that this project is a true testament to our value of delivering a safe and quality equipment. It is reflected in our daily operational checklist, weekly and monthly maintenance as well as our six monthly load test and inspection. Jenmon's crane specialists are diligent and professional when proceeding with their daily safety operations. Together with the customer's safety personnel, they check to prevent any possibility of a safety breach. Thus, putting a premium on "Safety".

More than 92,000 of timber sleeper were changed, with the rest to change in early 2017. The gantry crane at East – West Line (EWL), between Chinese garden & Lakeside stations was rounded off on 27th October 2016 and the crane at North South Line (NSL), Pasir Ris station was dismantled in January 2017.


Our aim is to ensure an operative crane on site at all times.
