What is the Role of Piling Rigs on an Overturning Construction Site?

Modern piling rigs, characterized as having a high center of gravity, usually weigh around 200 tonnes. 

One part of the rig referred to as “leader, can reach up to 30 meters high, thus by virtue of its high static weight together with all the physical forces exerted while the rig is moving or is actively working signify that the ground conditions underneath them are a critical safety issue. 

Every year, a handful of these rigs in the country topple bringing about serious property damage and alongside that also cause a business interruption. Scenarios like that are likely to occur because of inadequately maintained or prepared site surfaces. 

A plant’s stability will highly depend upon having in place a well inspected, prepared, and maintained site surface. Coordination between principal site contractors and piling firms is critical. Details of the plant need to be utilized and there should be the provision of bearing pressures. As for the site surfaces, preparing them correctly in advance is important before commencing any kind of work.  

Working platform:

Temporary geotechnical structures provide a stable and reliable working surface for mobile cranes, piling rig, and other similar heavy construction equipment. The working platform will serve as the piling rig foundation and there is nothing unusual about it if it weighs up to 200 tonnes.  

Working Platform Certificate: 

This certificate is the affirmation that a working platform underwent proper design and was constructed in compliance with design. Besides, adequate maintenance will be ensured to keep the platform integrity intact. This also necessitates the main contractor signature and should be relayed to the designated piling contractor before any kind of foundation or piling work commences. 

The certificate will also emphasize specific responsibilities, improving awareness on safety measures, and stressing on the importance of keeping and maintaining the platform in very good condition all the time.  

Working Platform

piling rig

This name is used when referring to a designated site area where the piling rig is supposed to travel during its delivery to the site, as well as when there are piling operations, and during its removal. The maintenance, design, installation, and repair works are all under the main contractor’s care and responsibility. The ground itself will need to be checked upon, and as far as its stability is concerned it needs to get confirmed, too. 

Working to affirm ground stability will sometimes also cover integrity and load testing, looking into or probing for any kind of irregularity as well as working on important remedial works. The ground must be free-draining, this will help in keeping water and slurry from build-up. 

In some cases, there is a need to install beneath the platform filter or separation membranes. By this measure, the weakening of the ground strength could be averted. 

Working Platform Certificates are now seen as an effective way to ensure the following: 

  • Adherence to the use of correct procedures
  • The ground working on is providing enough structural support to the piling rig
  • The likelihood of the occurrence of irregularities following toppling and local subsidence. 

What a visual inspection does will only cover for the ground surface. Checking out the quality of the fill, underlying material as well as its depth and construction, and lastly the application of the required material.  

A GPS Antenna for Your Car?

Car antennas come in many different sizes and shapes, from satellite radio antennas to GPS antennas, then from television antennas to terrestrial radio antennas. And not to mention, there are also cellular antennas. 

Every single one of them is hardwired for receiving and handling a particular kind of signal. Of all these, the monopole whip type of antenna remains the most predominantly used for cars. These antenna systems can also handle FM and AM radio transmissions. Carry on reading the rest of the article so you can glean upon some of the most common types of antenna for cars.

Terrestrial Radio Antenna

Normally, when cars are shipped from the factory itself, they usually come out with an antenna already installed. The antenna is neither window-mounted type of antenna, a flat type, or a monopole whip antenna. For the longest time now, the whip antenna has taken the place of being used as the standard. They also come in many different styles, so there are variations one can choose from depending on one’s preferences and specific needs. As for the whip type of antennas, they are often stationary and rigid while others extend automatically the moment that the radio is shut down or turned on.  

Television Antenna

Even if the FM radio and the analog VHF television at one point in time run parallel to each other, and there are even instances also that they overlapped, the shift into digital format rendered the TV broadcasts in many different countries to run on Ultra High Frequency or UHF spectrum. If for some reason, you need to see a television broadcast inside your car, you will need a dedicated antenna for this purpose. 

As earlier mentioned, there are several different kinds of antennas that are intended for car use. Included to this are the motorized satellite dishes, which is self-adjusting while the car is in transit or moving. For limousines, what they usually have instead are the iconic boomerang antennas. You can also use them in vans, RVs, and buses.  

GPS Antenna for Navigation

GPS navigation antennas usually have a built-in camera. If you want to further increase their level of accuracy, you can do so by adding up an external antenna. At the same, it also lowers the chances of losing a satellite lock. In contrast to the other kinds of antenna intended for car use, where most of which are inclined to be passive, a GPS type of antenna is inclined to either become active or passive.  

Cell Phone Car Antenna

Cell Phone car antenna comes in two forms: 

  1. The first one is the antenna that you can physically hook up to your mobile device. 
  2. The second type is the “signal booster”, they amplify and redirect the weak cellular signals such as active GPS antennas.  

The former is more rampantly used than the latter. But there have been several developments and improvements in the world of cellular technology. Those developments worked to its advantage in such a way that they paved the way for these antennas to be hardwired into the very design of receiver devices such as mobile phones and cars. 

Meanwhile, the so-called signal boosters remained stagnant in the regulatory area until such time that the 2013 FCC laid the needed guidelines for the groundwork of these devices.
