Defence Sector Cranes
High-integrity lifting that protects people, platforms and mission-critical assets
In defence operations, lifting is part of how critical work gets done. You may be handling regulated munitions, positioning high-value aerospace assemblies to tight tolerances, or supporting naval build and maintenance programmes, where a single handling event carries major safety and programme risk. The right overhead crane system delivers predictable motion, clear operating logic and a safety strategy designed around consequence, not convenience.
At Street Crane, we engineer overhead cranes and mechanical handling systems for demanding, defence-industry applications, combining robust mechanical design with advanced control. Variable Frequency Drives (VFDs) guarantee smooth acceleration, controlled deceleration and precision micro-speed positioning.
As a family-owned business with nearly 80 years of lifting expertise, we focus on solutions that lift standards, not just loads.

Crane solutions for defence environments
Defence lifting spans very different facilities, but the common thread is controlled handling of high-consequence loads. In naval settings, cranes support module moves, dry-dock maintenance activity and complex assemblies that demand stable travel and disciplined load paths. In aerospace, maintenance and assembly work often requires millimetre-level placement, low-impact motion and excellent line-of-sight control to protect sensitive components.
We work with your engineering, operations and assurance teams to map lifting into the real flow of your facility. That means matching crane type, geometry and duty capability to your building constraints, your handling method and your safety case expectations, then specifying the control strategy and protection features that reduce risk without adding unnecessary complexity.
Cranes
We have a large range of pre-engineered cranes to meet the needs of almost all industrial applications up to 250 tonnes capacity.
Components & Hoists
Designed for ease of crane assembly anywhere in the world, Street Crane kits include everything needed to build a complete overhead crane except the steelwork for the main bridge girder.
Spares & Servicing
Only genuine Street parts will ensure the lifelong productivity and reliability of your lifting equipment. Street parts are available from our warehouses in the UK and the USA. We also supply through our network of official distributors around the globe.
Overhead cranes engineered for safety-critical defence applications
Safety-critical lifting starts with fundamentals you can trust: stable structures, proven hoist design, predictable braking and a mechanical layout that supports inspection and maintenance. From there, defence applications often require micro-speed positioning for final approach, redundant braking strategies where risk demands it, and configurations that support controlled lifting of long, awkward or multi-point loads.
Where operations involve volatile fuels, munitions or other hazardous areas, crane specification may also call for explosion-protected components and disciplined electrical and instrumentation choices. For networked or digitised facilities, control-system security and access governance can become part of the specification conversation, particularly where cranes interface with wider site systems.
Key design considerations
Defence crane performance is shaped as much by handling quality and assurance as by capacity. Each project begins with the load envelope: weight, centre of gravity, dynamic factors, lifting method and the degree of placement accuracy required. From there we define duty cycle, classification, headroom and hook approaches, then engineer the travelling arrangement to suit your building and runway constraints. Where multiple cranes share a runway, or where lifts take place near people, tooling and high-value equipment, we design operating zones and safeguarding strategies that keep handling controlled and predictable.
Advanced VFD-based control is central where precision matters. Smooth acceleration and deceleration reduce shock loading and help manage sway, while programmable speed profiles and low-speed “inching” support careful final placement. In high-consequence applications, the safety strategy may include layered protection, for example secondary braking, overspeed/load-arrest approaches, enhanced sensing and clear operator control logic.
For harsh or exposed conditions, we also specify protection for components and access arrangements that make inspections and servicing practical over the long term.
Defence sector crane solutions
VX heavy-duty cranes
Where defence programmes demand the highest capacity, intense duty cycles and a strong focus on maintainability, VX open-winch cranes provide heavy-duty capability up to 200 tonnes with duty classifications up to ISO M8 / CMAA Class F. VX is engineered for resilience, with true vertical lift (zero hook drift) and an open-plan hoist layout that improves access to key components for inspection and service, helping reduce downtime risk in mission-critical areas.
ZX double girder cranes
For defence manufacturing and maintenance environments that need high handling quality with substantial capacity, ZX double girder cranes offer a versatile platform up to 80 tonnes. They are well suited to precision placement tasks, heavier tooling, and facilities where headroom and hook approach are decisive. Options such as auxiliary hoists and programmable control strategies support controlled handling when your process and assurance requirements demand it.
ZX underslung cranes
In aerospace hangars and large assembly halls where you want full-span coverage without introducing runway columns, ZX underslung cranes run on roof-mounted tracks and keep the floor clear for aircraft movement, work platforms and ground support equipment. This approach is particularly useful where building geometry and access routes matter as much as lifting capacity.
Portal and semi-portal cranes
Where the facility cannot carry runway loads, or where lifting spans indoor-to-outdoor transitions such as storage, staging and load-out, portal and semi-portal cranes provide robust coverage from 1 to 200 tonnes, with spans in excess of 40 metres available. Options such as rail-less semi-portal designs and cantilever arrangements can reduce civil works in some layouts and help extend handling reach beyond the legs where workflow requires it.
Special process cranes
Where standard crane formats do not fully address your handling method, assurance case or facility constraints, we engineer special process cranes to specification. This can include multi-hoist arrangements, process-integrated designs, enhanced monitoring, and safety architectures tailored to the consequence of the lift. Street has a track record delivering bespoke solutions for exacting sectors including military and aerospace, where performance, duty and safety conditions push beyond the ordinary.
Features that matter in defence lifting
In defence applications, the most valuable “feature” is predictable behaviour under load. VFD-based advanced control supports smooth starts and stops, stable travel and precision positioning to place assets accurately while reducing shock loads and limiting swing.
Just as importantly, defence cranes must be designed for long-term assurance. That means maintainable mechanical layouts, clear access for inspection, and a specification that considers the environment and the way the crane will be used over its working life.
Where facilities require networked diagnostics or integration with wider systems, control access and cybersecurity considerations can be addressed as part of the overall engineering scope, with the aim of protecting safe operation as digital connectivity increases.
Working as part of your defence operation
In defence settings, uptime is not just about the crane. It is about how lifting interacts with controlled areas, tooling, test equipment, maintenance teams and the wider flow of regulated assets through the facility.
We design crane systems around your operational reality, your building constraints and your assurance expectations, so handling stays smooth, predictable and safe shift after shift.
The result is lifting equipment that behaves like part of the operation, not a workaround around it.
Let’s design lifting you can rely on
As a family-owned engineering business, we build crane solutions that stay dependable over the long term, supported by straightforward, practical through-life support.
If you’re developing a new facility, upgrading an existing lifting capability, or tightening assurance around safety-critical handling, we’ll help you define a clear specification that fits the duty, the environment and the way your teams need to work.
