When you need to work safely at height consideration should be taken of not only where you need to get to at height to do your work, but also of how you are going to get there and the ground conditions where you are working. 
 
Tracked spiders are the most versatile forms of mewps (mobile elevated work platforms) as they can traverse and set-up on many different types of ground environments. The types of terrain that you need to consider are: - 
1. Sandy or other types of loose material, such as gravel, soft soil etc 
2. Boggy waterlogged ground 
3. Slopes 
4. Ploughed fields 
5. Restricted and narrow areas 
6. Obstacles in the way 
7. Uneven surfaces 
8. Internal, delicate floor surfaces 
 
The reason why spiderlifts can overcome these conditions is due to their design. They are light in weight and that weight is spread over the area of their tracks when moving, which reduces their ground pressure loading. The weight (point-loading) is then transferred and spread over a larger area when their outriggers (legs) are set, especially when using additional spreader plates at the ‘feet’. 
 
They say that a picture can save a thousand words, so please find below some examples of spiders overcoming the environments mentioned above.

High Reaching Solutions were asked to supply a solution to an awkward situation in Leeds. Decorators needed to work safely at height, 11 meters up and in a relatively confined internal space. 
They needed Scarlett Grace, our Platform Basket 13.80 Hybrid narrow tracked spiderlift as she was small and able to set-up and operate in a confined area. With her outrigger footprint of less than 3 meters, both in width and length and her boom just short of 3.5 meters in length without the basket attached. She also had negative tail-swing and her lithium batteries kept noise down to a whisper and engine fumes were non-existent, which is ideal for working internally.

Selina, High Reaching Solutions Platform Basket 22.10 EVO Hybrid tracked spider cherry picker, was requested to assist with chimney inspections and repairs at various properties around York. Our clients own staff as well as their subcontracted chimney sweep, Trevor Lund, were very impressed with Selinas abilities. 
On the first property Selinas amazing outreach came into its own with Trevor Lund getting to where he needed to be to inspect the chimney for stability and condition. After the first stack had been inspected Selina was moved to the rear of the building so the second stack on the list could be reached. This involved Selina negotiating a deceptively steep grass bank, so having her tracks on wide setting for the additional ground clearance and stability and running on her Lithium batteries so as not to disturb the residence of the neighbouring properties, she was able to perform the task without issue (please watch the accompanying video). 
If you require an excellent chimney sweep in and around the York area then please get in touch with Trevor Lund on 01904 760075 or 07801 529952, I'm sure he'll be glad to hear from you.

Adam Smith, an excellent carpenter in Scarborough needed to work at height safely on one of his jobs in Scalby village. He needed to replace some rotten wood on a gable end of a house which entailed cutting out the old rotten wood before replacing it with new oak on this listed building. He didn’t want to use scaffolding as this was a straight forward and relatively quick job for him so decided on a cherrypicker for speed and security. 
 
He came to High Reaching Solutions through recommendation and after we surveyed the site we suggested that Scarlett Grace, our Platform Basket 13.80 Hybrid tracked spider would be the ‘lady’ of choice. Her light weight, easy manoeuvrability and quiet lithium batteries would be ideal in this peaceful village location. The house he was working on is opposite a local landmark, a K6 telephone box, newly refurbished by local decorating company J.W. Decorating - Scarborough which now contains a Defibrillator instead of a phone, great idea to conserve heritage and benefit the local community at the same time. 
 
History shows us that working at height had to evolve to become quicker, cheaper and more importantly safer. This entailed moving on from old wooden ladders, wooden gantries and trestles and of course, hanging from ropes. No…not the around the neck type but around the waist or siting on a sling. 
 
We have now progressed to strong alloy ladders, alloy or steel scaffolding, rope access technicians (with purpose made equipment) and of course access platforms. 
 
Most are self-explanatory, but what is an Access Platform? Simply put, an access platform is a temporary work platform attached to the end of a boom and is manoeuvred into position via a system of hydraulically operated arms/booms. 
 
They are known by different names, here are a few; 
• Cherry Picker - used by most as a basic description of all access platforms. 
• Scissor Lift – a four wheeled vertical platform known by some as a 'flying carpet'. 
• Boom Lift - a general term for four-wheeled self-propelled boom type machines. 
• Spider - a term used for a tracked access platform with outriggers. 
• Trailer Mounted – a road towable platform that can be towed behind a car. 
• Truck Mounted – a platform which is fitted to a vehicle chassis. 
• Vertical Boom - a term used for stock pickers or manlifts. 
• MEWP - Mobile Elevated Work Platform, the descriptive term. 
 
Many maintenance and facilities companies come up against obstacles which they have to overcome in order to do their work safely and efficiently. High Reaching Solutions were approached by one such company, Aegis Fire & Security. They had a multitude of obstacles to overcome which included working from a mezzanine walkway as the floor was crammed with machinery, fenced of exclusion zones, electrical conduits, pipework, storage tanks etc. Basically the floor area was totally covered except for marked pedestrian walkways, hence the installed mezzanine walkway. 
Aegis Fire & Security needed to work at height safely and work from the mezzanine walkway as mentioned to install their fire and security system. This created another problem as parts of the walkway were very narrow and this combined with a weight limit meant there were very few options. Scaffolding the work area from the floor had been looked at, but the complexity, scale, time constraints, high possibility of damage to machinery and equipment during the build and disassembly and the very high cost meant this really wasn’t an option. They had contact a few very well-known companies within the access industry before being recommended to us by one of them, Promax Access
 
One of High Reaching Solutions regular clients, N Dean Tree and Garden Services of Malton, North Yorkshire, had the task of dismantling a very dangerous tree which was unsafe to climb and so requested the services of ‘Selina’, our 22m tracked spiderlift to help them do it safely. The tree was rotten in the centre and was in danger of falling and although situated in a garden the tree was awkward to get to and no other form of cherrypicker could get close enough to do the job. Nick has used ‘Selina’ on many occasions and found her controls precise and easy to use, along with her adjustable track settings to get through narrow gates and her adjustable leg settings enabling setting up in tight and awkward areas very beneficial. Being only three tonnes in total weight which is spread over the area of the tracks whilst travelling and then over the footprint when her legs are down gives a very low ‘point-loading’ and therefore leaves very little evidence that she was even there, which is a bonus for all concerned.
