New Pitless Drive Towline Conveyor Diminishes Costs & Improves Performance
The new Pitless drive system, for SI Systems Lo-Tow® towline conveyor system helps reduce system investment, simplify maintenance, and speed up implementation.
The Pitless drive utilizes a steel housing that is mounted in a shallow recess rather than a pit. The Pitless drive simply embeds into the concrete slab when the trench is poured during installation. Also, the Pitless drive’s take-up does not require a pit either and installs in a 6” deep trench. By not having to form pit walls, the installation of the Pitless drive and take-up system saves a considerable amount of time, labor and cost.
For decades, towline, drag chain and other similar “in-floor chain” conveyor systems required large pits to house their drive and take-up system. Appropriately, OSHA considers pits like these to be a “Confined Space” and has developed a standard (OSHA3788 ) which can require permits, training, and other construction and maintenance complications.
With SI System’s pitless drive/take-up system, the need to design, form, pour and create a pit is eliminated. The labor and materials associated with a pit’s civil/concrete work can often cost over $12,000 per pit.
Eliminates Confined Space Requirements
Towline pits typically satisfy OSHA’s defined criteria for a “confined space,” as follows:
Depending on your local building laws and OSHA representation, companies may have to schedule an on-site OSHA evaluation, get permits, create employee training procedures, provide the proper ventilation equipment, safe entry and exit documentation and training, create a ventilation system, deploy an air testing procedure, have available personal protective equipment (PPE) and more.
The Lo-Tow pitless drive system eliminates all of this concern, cost and risk associated with the OSHA regulations, allowing easy access without entering a pit.
