Beam Erector (DJ Series)

a. Introduction

DJ Series Beam Erector is a Single Box type Launching Gantry for simply supported precast Beam installation. It is a very effective machine that offers high speed precast beam installation.

The fastest installation speed recorded was 30 PC Beams in 8 spans within 24 hours for a railway bridge project.

Standard Model up to 60m span length is available. From confirmation of order to the completion of the fabrication up to ex-work condition is as short as 2 months. Shipment to the America continents take another 4-5 weeks which means in total only less than4 months is needed and for Asia Region it takes less than 3 months to reach the destination port.

HCR provides door to door delivery where the machinery is delivered all the way to the site upon request.

DJ Series Beam Erector was used to install the precast beam above high speed train track that is already in service. Safety check has to be maximized under this type of construction.

This project in Greece was having a slope up to 6.9% and Radius on plane was around 200m. Installation with Mobile crane was not feasible due to difficult terrain. DJ Series Beam Erector provided the best solution for the contractor.

b. Safety Feature

These safety features are included in every Beam Erector supplied by HCR.

1. Hoist secondary brake, spinning speed control, load encoder

2. Level encoder on Main Girder, Verticality encoder on supports, real time readings display

3. Anemometer, lightning arrestor

4. Video recording and monitoring comes in the

package with Operator Cabin. If Remote Control tobe used the video recording will not be needed unless otherwise requested

5. Operation data recording system

c. Handling Various Types of Beam

Photo above and photo on the left were taken on the same project and on the same DJ Beam Erector. It was two different types of beam in the same project. DJ Series Beam Erector can handle various types of precast beam without modification. This is one of the important features that enhances its reuse value.
