We are registered contractors for T-Mobile, 02, Airwave, 3, Crown Castle, and NTL. CRI are capable of logistical asset management of free issue materials to deliver to site co-ordinating with the supply of various feeders Just-In-Time (JIT).

All riggers have Andrews/RFS LDF/LCF jointing certificates.
We at CRI have the unique position of ensuring our quality of installation by way of 2 of our in house auditing teams are actual Directors of the company, therefore steering the company through performance and indoctrinating the crews to a high level of attention to detail.

We offer the full package when it comes to erecting or de-commissioning telecom structures. Normally access for craneage is provided by the principle contractor however we can survey such eventuality if temporary access (i.e. Trackway, Type 1 compact road) is required.
All our crews are slinger/signaller trained and CRI can also provide a Crane Appointed person or the PC can provide a contract lift where we shall sling the tower and erect or dismantle any size or shape tower. CRI riggers are Latchway/Railock approved. Where cranes are restricted, CRI can hand build sites piecemeal. We have a purpose designed 12m Derrick Pole specifically for small to medium size towers, which has a reach of 10 meters and can lift panels at a time up to 1000kg SWL, (price on application).
Larger Alphaman Derricks available for larger structures.
We can also remove towers from site and deliver to designated drop off or scrap as required to EU regulations.
All our crews have been extensively trained on Anritsu Site Master S331B/S251B and S251C's. Our Training co-ordinator has been trained to F004863D Registration and we at CRI hold regular testing specification workshops incorporating all the latest operator spec's and software changes to bring our crews up to speed on ever changing standards.
Even if we have not installed a site, we offer the service of testing rigs, say for instance emergency call outs, auditing or maintenance contracts.

Ancillary Steelwork Design, Supply & Install
Supply and Install Such a simple task of mounting steel can become an expensive exercise for the client. We do not believe this needs to be the case. We have a wide range of universal antenna pole mounts, delta frames and rocket head frames already designed.
If the client can provide us with a mid pole height with leg size (CHS/Angle- on a rake?) We can provide steel and labour to suit at short notice. If however the leg size or often space on the tower is unknown, we can survey the site at short notice, often within 48 hours to provide a practical solution. We carry most pole mounts in stock. However, if you require some thing more bespoke, CRI have an excellent partnership with a steel fabricator in Sheffield who can fabricate designs and hot dip galvanise the finish in quick time.

Microwave Installation and Commissioning
CRI operatives are widely experienced in installing and commissioning microwave links for all the major operatives such as Orange, T-mobile and Vodafone. Material management is our speciality and can store a wide range of antennas and radios for clients with a rapid response approach to installing links or responding to links that have gone down. We also offer a Line of Site service to complement the installation side of transmission links.

Rooftop Installations and Stub Masts
No two rooftops are ever the same therefore attention to detail is paramount. An in depth survey of a rooftop installation is carried out before installation. CRI can also design a planned route for the feeder and install the feeder tray/ladder to a high standard integrating it into the existing LP system.
CRI will also land any stub mast onto the roof and carry out all the slinging of the structure.

We are highly proficient at erecting streetwork poles and monopoles using industry standard rigging techniques. As Principle contractors may be aware, some poles do not come with dedicated lifting points therefore established methods and techniques need to be employed which CRI have extensive knowledge.

CRI have the management expertise that has constructed sites ready for tower erection and rigging. Sites constructed for 3, T-mobile, Airwave and 02. We have in-house groundwork teams who will also erect fencing only if required. Our sole and trusted NICEIC contractor would carry out LP and electrical integration with over 18 years experience within telecoms. We take great care in constructing our sites and pay attention to detail working on a right first time basis.

Tower Rescue/IRATA Trained rope Access
All our operatives are Tower top rescue trained and all our vans carry tower rescue kits. CRI also have fully trained rope access personnel with IRATA Level 1, 2 & 3 training.
We at CRI will train candidates up to be proficient climbers and be rooftop aware and trained in the skill of rescuing from a tower. We will be called out at short notice to assist in the rescue of any personnel who may be trapped or injured up a tower or structure.

Often cabin and tower logistics can be a nightmare to land. CRI trained operatives can deliver towers and cabins by way of manitou plant or helictopter solutions.

We believe it is a natural step for our rigging company to offer a maintenance side to our services. We have personnel in-house who have worked on extensive maintenance contracts who understand the need for accurate recording of data and refreshing a site on an annual basis. We view maintenance as an important side to installations and are committed to a quality install with an equal quality of the upkeep of a cellular site.

Whenever there is an event such as Glastonbury or the British Grand Prix, CRI understand the importance of being quick to respond and flexible in approach to offer the client a temporary solution to an upturn in demand on the networks. We have rigged in the past many temporary sites and have tacit knowledge in techniques employed to get these sites up and broadcasting.

As we all know the weather is so unpredictable in the UK. Sites can go off air from time to time due to inclement weather. The operator at the NMC sees warning lights on a screen but cannot fully ascertain as to why a site may have gone down. We can respond at a level of notice to attend site with experience personnel and examine why the site may have gone off air. We carry a running amount of stock within the vans in an attempt to fix a problem with a replacement. More often than not the site may have water ingression and needs cleaning. Maybe a feeder is damaged by falling debris or ice. We can carry out a full systems test and then examine the problem. We would pick up antennas and amplifiers from a designated point if need be to swap out a faulty unit all within the call-out rate.
