2 Survivor PT - Pit Type Truck Scale
1.2 Installation
The modular sections of the Survivor PT truck scale are shipped pre-assembled and ready to be placed into position
on temporary setting blocks using a crane capable of handling 10,000 lbs. The individual modules are bolted
together and the deck is leveled in final position flush with the top of the pit. Mounts are shipped pre-assembled
with load cells, adapters, and flexible conduit sections attached. Mounts are installed to the level of the deck, then
anchored and grouted to the foundation. Cabling is run in conduit and electronic equipment connected to finish the
installation.
The general assembly order is summarized below:
1. Set deck modules into position on setting blocks and bolt deck modules together.
2. Install outriggers and deck channel coping.
3. Place deck into final position even with top of pit.
4. Assemble mounts with load cells to the deck unit; remove setting blocks.
5. Install mount anchor bolts and grout beneath mount plates.
6. Install corrugated sheet metal, rebar and pour concrete.
7. Run cabling through conduit; make electrical connections.
8. Connect indicator and peripheral devices.
9. Calibrate scale.
1.2.1 Foundation Slab Cure Period
Standard concrete reaches full strength after a 28-day cure. Note that the concrete foundation must cure in a moist
state for at least seven days (three days for high-early concrete). At seven days, standard concrete is approximately
75% of its maximum strength and can handle moderate loads. Loading of a slab before it reaches 75% of maximum
strength may damage the foundation.
1.2.2 Assembly Time Estimates
When scheduling installation for a typical three-section, 70' truck scale, plan for a two-hour minimum crane rental
to position the sections.
A two-man crew, aided by a crane operator, can unload modules from the truck, place them into position and bolt
them together in one to two hours. Mount and load cell installation requires approximately two hours. All electrical
wiring and final connections can normally be completed the same day.
These estimated times may vary.
1.2.3 Recommended Tools and Equipment
The following is a list of recommended tools and equipment necessary to assemble and install the Survivor PT
truck scale:
• One heavy duty crane, equipped with chains or cables, for module placement;
• Rotary hammer drill (3/4");
• Drill with 5/16" socket for installing sheet metal screws through corrugated sheeting;
• Carbide masonry bit (3/4" x 30");
• Two low-profile, four-ton hydraulic jacks;
• Setting blocks (15-1/4") and shims to total 13-3/4" height;
• Torque wrench (800 ft-lb);
• Socket wrenches to 1-5/8" (drive compatible with torque wrench);
• Box end wrenches to 1-1/2";
• Open end wrench set (7/16"-3/4");
• Four-foot bubble or construction level (transit);
• Small torpedo level;
• Spacers for deck-to-pit wall alignment;
• Hammers, maul, pry bar;
• Hand tools for pulling and connecting electrical wiring and sheet metal cutting and trimming.
