Here's a system that can make your SpeedStand warning line system cheaper and easier to use. The backbone of the system is the efficient
use of carts and pallets to handle SpeedStands. A special pallet is built that will fit on a 2-(or 4) wheel cart and serve as storage
for about 20 stands. As shown in Fig. 1, the pallet fits in the cradle of the cart. It includes posts and a rear side to easily and
safely stack the stands along the length of the cart.
6) Carts quickly distribute the stands on the roof to set up the warning line system and begin the roof work (Fig. 5).

The benefits of this arrangement include:
1) Pallets of stands can be forklifted onto carts.
2) Loaded carts can be forklifted onto trucks (Fig. 2).
3) The carts and stands fit conveniently inside the cart frame and use less room in the truck.
4) The cart and stands can be easily positioned in the truck.
5) At the job site, the carts can be either hoisted onto the deck (after suitably securing the stands to the cart) or if loading is performed with a liftbed truck, they can be rolled on a ramp directly onto the roof deck. (Figs. 3 & 4)
7) After set up, the carts can be used to unload materials and equipment, haul debris, and aid the roof work (Fig. 6).
8) When roof construction is complete the carts are used to gather and transport the stands to the unloading area.
9) The carts and stands can be either rolled or hoisted into the trucks.
10) The stands are easily forklifted to storage at the shop.
A warning line system is basically several hundred pounds of stands that, like other equipment, are handled several times. this cart system reduces handling labor, and allows one semi-skilled worker to quickly set up the warning line system so that the roofing job can be attacked directly by a fresh crew.
The construction details of the pallet are show in Figs. 7-10. The width and length are adjusted to match the bed of your carts. The pallet can be built from scratch or can be modified from a similar pallet.
Safety pays. Instruct the crew in safe practices to use when using this system. A cart loaded with 20 SpeedStands can weigh as much as 600 pounds and requires special caution.
Stack the stands on the pallets so the carts resist tipping over. A Garlock 2-wheel cart has a long bed and a long axel-to rear distance. To prevent tipping, the stands must be stacked with their top ends to the rear (Fig. 11).A Cleasby 2-wheel cart has a short axle-to-rear distance and can allow stacking with the bottom end of the folded stands to the rear (Fig. 12). Other carts should be tested to determine the safest stacking direction.
Forklift carefully. Inspect the roof structure and deck to ensure it will support the weight of a loaded cart. When hoisting a loaded cart with a crane, secure the stands in the cart with a strong rope and lift with straps so the cart remains horizontal. Ensure personnel are not under the load. When moving from a raised liftbed truck onto the roof, provide a sturdy, well supported ramp that can easily support the weight of the cart and the workers necessary to control it on the roof. Use care when moving to control and avoid damage to people and property.
