What sizes and step configurations are available?
There are 25 models, offered in 3-, 4-, 5-, 6- and 7-step configurations. Each step count comes in five variants, identified by the last number in the model code: 8, 20, 32, 44 or 56. The range runs from the 3-step COLV-3-34-8 at the low end to the 7-step COLV-7-82-56 at the top.
How do I read the COLV model number?
The first number is the step count, and it matches the written description — COLV-5-58-20 is a 5-step unit. The middle number is tied to that step count: 34 for 3-step, 46 for 4-step, 58 for 5-step, 70 for 6-step, 82 for 7-step. The final number varies independently across 8, 20, 32, 44 and 56. Units for those two figures are not stated in our product data.
What is the price range, and what makes one model cost more than another?
Prices run from $1,086.57 to $1,851.20. The least expensive model is COLV-3-34-8 and the most expensive is COLV-7-82-56, so cost rises with both step count and the final size figure. For reference, COLV-4-46-32 and COLV-3-34-44 are both $1,260.00, and the 6-step COLV-6-70-20 is $1,437.72.
Do these ladders need electrical or air supply?
No. A cross-over vertical ladder is a passive step-and-platform structure with no motor, hydraulics or controls, so there is nothing to wire or plumb. No electrical, pneumatic or hydraulic requirements are listed for any of the 25 COLV models in our product data.
What warranty comes with them, and where are they made?
They carry a 1-Year Limited warranty and are made in the USA by Vestil Manufacturing. That applies across the full COLV line, from the $1,086.57 COLV-3-34-8 to the $1,851.20 COLV-7-82-56. What the warranty covers in detail and how claims are handled is not part of the product data shown on this page.
Who is this equipment for, and what should I check before ordering?
It is for facilities where workers need a safe way to step over an obstruction — a conveyor, pipe run or machine base — instead of climbing over it or walking around. Fixed ladders and stairways in US workplaces fall under the Occupational Safety and Health Administration's walking-working surfaces rules, so confirm the configuration you pick fits your installation. Check clearances against your own measurements, since dimensions are not listed here.
