Joyce Dayton Jacks: Taking Customer Service to New Heights
The Problem:
An oil rigging company requested that Joyce Dayton provide a solution to assist in raising mast beams on the rear of a trailer and to lift the coiled tubing injector to the well head for oilfield services. They required two 14 Tonne, 11.5m travel stainless steel screw jacks and two 31 Tonne, 3m stainless steel screw jacks.
The mast beams can be lifted to a vertical or less than vertical position, depending on the angle that the well has been drilled. The two 31 Tonne, 3m stainless steel screw jacks are used to elevate the mast beams to the correct angle. The two 14 Tonne, 11.5m travel stainless steel screw jacks are used to raise the coiled tubing injector to working height.
An 11.5m long stainless steel screw is hardly an off the shelf item... even with Joyce Dayton’s wide inventory.
The Solution:
Joyce application engineers proposed a “spliced screw” technique. Typically, when splicing screws it is very difficult to align the Acme threads, which can cause binding and excessive wear of the jack components. However, instead of joining pre-machined screws - which makes perfect alignment of the Acme threads nearly impossible - Joyce spliced the stainless steel screw stock before machining. Essentially this creates one continuous piece of stock that can be machined as one screw, eliminating the misalignment.
Although another jack manufacturer declined to bid on the project, Joyce Dayton stepped up to the plate and developed an innovative solution. Starting with a standard “off the shelf” product and adapting it to meet the customer’s needs is one of Joyce Dayton’s strengths. The Joyce Dayton Application engineering team is ready, willing and uniquely able to help you design and install a solution to virtually any lifting or positioning application.
