Q What is a tail or a flap?
A A tail or flap is normally on one (or both) end of a tarpaulin body to hang down on the front or the rear to make tarping a load easier. Example: Standard Lumber Tarp (SL18) 8' drop with 8'x 8' tail.
Q What is a gusset?
A This is an extra small flap sewn to each side of a tail to act as a rain flap.
Q What is a drop?
A This is a term to refer to the height of the load. Example: A trucker has an 8' high load which equals 8' drop; so on a normal 8' wide trailer, the tarp would need to be 24' wide; 8' wide trailer + 2 sides * 8' high = 24'.
Q What are Dee Rings and Dee Bands?
A Dee Rings are steel rings shaped like a "D", which should be welded to prevent them from separating when a load is put on, such as tying down a tarpaulin. Dee Bands are a strip of webbing, 1.5" black polypropylene, to which a Dee ring is attached with a 2" seatbelt type webbing. Dee bands are sewn on and spaced according to the customer's needs; our standard Dee ring spacing is 30" on center unless otherwise specified by the customer.
Q How do you figure the rise for a Side Kit tarp?
A Measure the highest point of the rear bow and subtract the measurement of the side. Example: Measurement from the top of the bow to the bottom of the bed is 72" and the side is 48" high; 72"- 48" = 24" Rise.
Q How do I measure my truck for a tarp?
A The bed of the truck is a good start, such as 8' wide by 20' long. Then determine the height of the load you will carry, such as 4' tall. Add the width of the truck to the height you will need on each side, ex: 8' wide + 4' tall + 4' tall = 16' in width. Next, decide if you will need to cover the ends of the load as well, if so, then a tail may be added on each end. The tail would need to be the width of the truck by the height of the load; 8' x 4'. So in this case the size of the tarp needed would be: 16' x 20' with an 8' x 4' tail on each 16' width. If your loads are sometimes shorter, Dee bands and Dee rings can be added to adjust the height of the tarpaulin.
Q When buying an electric tarping system, is the GHS 2600HT the only thing I need to buy?
A If this is the first tarping system, manual or otherwise, you will also need a tarp and a wand system to complete the covering and un-covering of your load.
Q Can I convert from your manual wind up system to your new ground control unit?
A

Yes. If your current wind-up system is the GHS 1500/ETA, the only parts needed to convert to our GHS 1600 Ground Control System are:

  • GHS 1601 — Lower Chain Cover
  • GHS 1602 — Upper Chain Cover
  • GHS 1603 — Cover Mounting Bracket
Q Can I convert from a manual wind up system to an electric system, and what additional
parts would I need?
A

If your manual system is currently a GHS 1500/ETA or GHS 1600, to convert to our electric system, GHS 2600HT, you would need to purchase:

  • GHS 2601 motor
  • GHS 2602 Mounting Plate
  • GHS 2605 Rotary switch & Mounting kit
  • 75' GHS 2607 wire (measure to make sure, don't forget inside the cab)
Q What type of steel or aluminum wand system should I choose?
A

The type of steel or aluminum wand system is determined by many factors, such as the design of your truck, the appearance of the finished product and the price. The GHS 5000 series is designed to be a low cost workable unit for most dump trucks. These units come with several options such as lower spring or side mounting spring and straight or angle arms.

The side mounted spring units are less expensive; but, the springs may mar the paint on the side of your truck. The lower spring mount is more costly; but, since the springs are mounted under the body they are less likely to mar the paint. The angle arms are a great option to help eliminate the dozer operator from hitting the arms when the load is uncovered.

The GHS 6000 series is designed for a heavier and better looking unit as it is a larger steel and chrome system. It has spiral torsion springs and also comes with angle arms. The GHS 8000 series is our best looking system with torsion spring technology and every unit comes with respective angle inserts at no additional cost. These units are also available for the longer trailers, not just for dump trucks.

More information about selecting compatible products can be found in our Quick Reference Charts.
