An in-depth analysis on the access equipments for bridge maintenance
There are thousands of old bridges in the country many of which are in decaying state needing immediate repairs. Therefore, special purpose vehicle in the form of access equipment can only be termed as the need of the hour.
Access equipment are among the highest safety equipment. These are available both in vertical and articulated forms. A normal height of access equipment is from 5 to 50 metres and up to these heights equipment is easily available with the Indian rental companies. In overseas countries, access equipment is mostly used in bridge inspection by project and safety teams. For the painting and maintenance of the bridges, these machines are much safe and productive.
Role of advanced access equipment for bridge maintenance
Cavas Dumasia, Vice-President, Sales & Marketing-Material Handling Division, Godrej & Boyce Manufacturing Company Ltd says, “For the vertical access, the company offers rough terrain scissor lift for bridge maintenance (painting, civil work, electrical work etc). However to reach remote access, we can offer Boom lifts where vertical reach & horizontal reach is achieved by Single Machine. We also provide special attachment to work under bridge for maintenance.”
Sunil Malhotra, Managing Director, Appletree Building Maintenance Pvt Ltd says, “There are many kinds of access equipment that can be used depending on the complexity of the structure. The various methods used for maintenance and inspection would be fixed motorised gantries, fixed manually operated gantries, and fixed suspended platforms. These access systems are fixed on the bridge structure for rotational inspection and maintenance. Other than these there is temporary access systems which can be called upon when required, these include articulated aerial platforms, telescopic aerial platforms.”
