Featured Equipment

Our derricks fit inside the elevator.

Modular construction. Components sized to ride a standard construction hoist. Each unit ships with its own drawing toolbox and load chart — quoting and planning happen on day one, not week three.

Design & Specification
Step 01

It starts with a load chart and a site constraint. From there our engineers spec the mechanics, the electrical, and the hydraulics — together, not in silos.

  • Mechanical engineering
  • Electrical & controls engineering
  • Fluid power (hydraulic & pneumatic)
  • OEM derricks (ASME B30.6)
  • OEM winches & hoists (B30.7)
  • Below-the-hook devices (B30.20)
  • 3rd party design reviews
  • Feasibility studies
Fabrication & Build
Step 02

Our UL508A-certified panel shop builds the box that controls the equipment. Same building. Same team. Full traceability from schematic to ship.

  • Electrical panel fabrication (UL508A)
  • VFD control system packages
  • Schematics & documentation
  • Communications & networking
  • Radio pendant control systems
  • Data & event logging systems
  • Hazard analysis & risk assessment
  • Obsolescence solutions
Software & Controls
Step 03

Safety PLC. Motion control. PID tuning that holds. Drive platforms we know inside out — Rockwell, Siemens, ABB, Beckhoff. Every behavior documented.

  • Safety PLC & HMI development
  • Ride & show control systems
  • Wave pool control systems
  • Crane monitoring (LMI)
  • Motion control & PID tuning
  • SRP/CS — safety related parts
  • Theory-of-Operations docs
  • FMEA documentation
Commission & Support
Step 04

Factory acceptance, site acceptance, then the keys. Our engineers are on-site for commissioning and on the phone when something faults on second shift — 24/7.

  • FAT — Factory acceptance test
  • SAT — Site acceptance test
  • On-site integration
  • Commissioning & tuning
  • Operator training
  • 24/7 engineering line
  • Field service & retrofits
  • Parts & obsolescence support
