The latest addition to our fleet soon to be with us is LOTTIE, a lithium/diesel hybrid tracked spider with 19.9m working height and 9.5m side outreach. 
 
She was born in Italy at Platform Basket and they have kindly kept us informed of her growth with these progress photos. A very close eye was kept on her as she grew, ensuring healthy and steady growth through her development. 
 
Platform Basket didn't need to cut her umbilical cord as she has remote control capability. They did however, ensure that all her functions worked correctly, including: 
 
Kubota diesel and Lithium power sources 
Remote Diagnostics 
Duel Speed Tracking 
Track Widening System 
Duel Boom Telescopic Operations 
Basket Rotation 
250kg SWL (Safe Working Load) Unrestricted 
Automatic Stabilisation 
Automatic 'Go-Home' Boom Function. 
 
First Parts Trolley with Lotties Components
Second Trolley with more Components
These two trolley's are the start of Lotties' 'Birth', her 'growth' will be steady and monitored all the way through. 
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.
