Temperature range: -50° to 140° F (-45° to 60° C)

Ultimate Safety Factor: 5:1 minimum USF

Construction:

Pressure bar - Certified & traceable aircraft quality E4340 steel

Shackles and pins -

Low capacity range - A4140 forged steel (pins machined from AQ E4340 steel)
Med/High capacity ranges - Skookum Gold

Standard or Crosby G-2140 Grade B alloy steel

(Med capacity pins from AQ E4340 steel)

Heat treatment:
Pressure bar-HRC 36-40
Low capacity shackles-HRC 34-40
Low/Med capacity shackle pins-HRC 43-50

Proof load:
150% proof load applied to pressure bar after machining and prior to nondestructive testing.

Nondestructive examinations:
Magnetic particle inspection per ASTM E1444 conducted on:
-every pressure bar in all capacities
-every low capacity shackle and pin

Corrosion protection:
Electroless nickel plating from 0.0002 to 0.0005 inch offers excellent corrosion resistance, typically permits future inspections and eliminates hydrogen embrittlement concerns. Applied to pressure bar, shackles and pins.

Zero control: Zero up to 20% of capacity. Zeroed load must be considered as part of ultimate load.

Calibration: Traceable to NIST with three confirmation runs.

Documentation: Includes User’s Guide, certificate of conformance and signed calibration certificate.

Carry case/crate:
low capacity 5" dial - plastic carry case
low capacity 10" dial - steel carry case
all med and high capacity - reinforced plywood crate

Optional Klaxon signal alarm:

Rated at 104 dB at 1 foot. Must be installed at time of manufacture.

Optional Auto control switch:

Rated 250 VAC or 28 VDC, 5 amps, resistive. Must be installed at time of manufacture.

Periodic proof loads: Controlled 150% proof loads permitted annually.
