Vandenberg Building 9320 Hoist/Trolly/Crane Replacement i
DESCRIPTION OF SERVICES
Scope This Statement of Work (SOW) defines the tasks required for the removal of the existing indoor overhead crane system and the engineering, fabrication, delivery, installation, testing, and commissioning of a new underhung single-girder bridge crane system with two independently operated trolley-mounted hoists in Building 9320 at Vandenberg Space Force Base (VSFB), California. This SOW applies to non-critical lifting operations only. Operator training, daily inspections, and routine crane operations are performed by Government personnel and are outside the scope of this contract.
Existing Conditions The existing facility system consists of an indoor overhead crane, hoists, runway rails, electrification, and associated controls. The Government will provide existing facility drawings and available runway documentation for reference. Technical requirements for contractor on-site field verification of all critical dimensions and structural conditions are detailed in Section 3.

Requirements New Crane System General Description The contractor shall design, fabricate, and install a complete indoor under-running, single-girder bridge crane system serving the existing runway in Building 9320. All specified ratings are in U.S. short tons (2,000 pounds = 1 ton). The crane system shall include:
One under-running single-girder bridge rated for a capacity of 4 tons, CMAA Class D service classification, designed for indoor, non-critical, industrial service.
Two cross-mounted 2 ton capacity electric wire rope hoists mounted on trolleys, configured for independent lifting of non-critical loads.
Integrated system controls that mechanically and electrically limit the combined simultaneous lifting load of both hoists to ensure the total capacity of the bridge and runway is not exceeded under any operating condition.
Hoist and Trolley Performance The contractor shall ensure each hoist and trolley meets the following performance criteria:
Rated Capacity: 2 tons per hoist.
Lift: Minimum of 36 feet, or sufficient lift for the building and application as verified by field measurement.
Hoist Speed: Nominal speed of 15 Feet Per Minute (±10%) (FPM) utilizing Variable Frequency Drive (VFD) controls, including a micro-speed positioning function operating at 25 percent of nominal speed.
Trolley Speed: Nominal speed of 50 FPM (±10%) utilizing VFD controls, including a micro-speed positioning function operating at 25 percent of nominal speed.
Duty Class: Hoists shall meet ASME HST-4 H4 duty classification for high-volume industrial handling.
Hooks and Suspension: Hooks shall comply with ASME B30.10 and incorporate spring-loaded safety latches. Lower hook blocks shall allow hook to swivel to minimize rope twist and load rotation.
Reeving: Hoists shall be dual-reeved with equalizer sheaves in accordance with SSCMAN 91-710, Volume 3, paragraphs 6.3.1.11 and 6.3.5.1.8.
Bridge and End Trucks The contractor shall design, fabricate, and assemble the bridge crane structure in accordance with the following:
Bridge span, wheelbase, and end truck dimensions shall be matched to the existing runway geometry as verified by the contractor's field measurements.
The bridge girder shall be rated for a 4 tons capacity, under-running configuration, CMAA Class D service, designed in accordance with CMAA Specification No. 74 and ASME B30.17.
End trucks shall be driven by dual-motor VFDs with a nominal travel speed of 95 FPM (±5 FPM), incorporating AC motor brakes with manual hand-release mechanisms.
The bridge structure, end trucks, and runway attachments shall be detailed and built to prevent the crane from derailing or walking along the tracks during seismic events, in accordance with the seismic hazard provisions of SSCMAN 91-710, Volume 3, paragraph 6.3.4.2.2.
Electrical and Controls The contractor shall provide a complete crane control system, including:
Power Supply: Incoming power feed from disconnect is 460 Volts AC (VAC), 3-phase, 60 Hertz (Hz), with 115 VAC control power circuits. The contractor shall run power from disconnect on.
Control Enclosures: Enclosures shall be NEMA Type 12 steel control enclosures. If alternative environmental conditions require NEMA Type 3R enclosures, the contractor shall submit a technical justification to the Contracting Officer for written approval prior to procurement.
Drives: Solid-state VFDs shall control all crane motions (hoist, trolley, and bridge) and shall include line reactors, output reactors, dynamic braking resistors, and over-current protective devices.
Motors: All motors shall be inverter-duty rated with Class H insulation and Class B temperature rise, incorporating integral AC disc brakes with manual hand-release levers.
Pendant and Radio Controls: The contractor shall provide a primary pendant control station and a backup radio remote control system. Both control systems shall include functions for: mainline emergency stop (E-stop), Hoist 1 hoist/lower, Hoist 2 hoist/lower, Trolley 1 & 2 travel, Bridge travel, able to support 2 speed operations, warning horn, and auxiliary safety functions. The pendant station shall be physically suspended from a separate track to run parallel to the bridge girder.
Control Circuit Design: Control circuits shall incorporate electrical and mechanical interlocking to prevent simultaneous opposing commands, provide fail-safe stop functions, and comply with ASME B30.17 (Monorails and Underhung Cranes), ASME B30.16 (Overhead Underhung and Stationary Hoists), and NFPA 70. Over-travel limit switches and E-stop circuits shall be hardwired directly to the mainline contactor and shall not rely on programmable logic.
Safety and Lockout Features: The main electrical control panel shall incorporate a physical lockable disconnect switch and a keyed lockout switch to prevent unauthorized operation. Loss of radio frequency (RF) signals shall automatically trigger a hardwired emergency shutdown, reverting the crane to a safe, motion-inhibited state.
Overload Protection Each hoist shall incorporate an integral, non-adjustable mechanical or electronic overload protection system in accordance with ASME B30.16.
The overload protection system shall interrupt hoisting power when the load exceeds 110 percent (+0% / -5%) of the rated capacity of the individual hoist (2.5 tons), while permitting controlled lowering operations.
Overload settings shall be sealed and configurable only by qualified crane maintenance personnel following manufacturer instructions. Field adjustment by crane operators is prohibited.
The hoist control system shall support torque-proving functions and adjustable overload test settings, including keyed overrides and load weight readouts, to facilitate required proof-load testing.
Safety Features The crane system shall include:
Two Independent Upper Hoist Limits: A primary control-circuit upper limit switch that stops upward motion (automatic reset via reversing control) and a secondary final upper limit switch that mechanically interrupts power to the hoist drive motor, requiring a keyed manual reset.
Travel Limits: Hardwired bridge and trolley travel limit switches to prevent the crane and hoists from striking physical end stops.
Warning Horn: An audible, operator-controlled horn (minimum 90 dBA at 10 feet) to warn personnel prior to and during load movement.
Travel Strobe: A red strobe light mounted on the bridge that automatically activates and flashes whenever the bridge or trolley is in motion.
Main Disconnect: A lockable, manual main power disconnect switch accessible from ground level.
Capacity and Warning Signage: Sized and lettered capacity placards on both sides of the bridge girder and hoists, and warning safety decals on the operator controls in accordance with ASME B30.17, ASME B30.16, and AFMAN 91-203.
Environmental and Finish All components of the crane system shall be designed for indoor, non-hazardous industrial environments.
Hoists and trolleys shall be painted safety yellow. The bridge girder and end trucks shall be finished with an industrial-grade rust-inhibitive primer and safety yellow polyurethane topcoat.
