02 — What we do

When a component weighs 1,800 tonnes and cannot fail — we are the team that engineers the moment.

JMR Lifting Solutions & Engineering is a specialist heavy-lift and engineered transport contractor. We plan, engineer, and execute the world's most complex lifts — refinery reactor changeouts, offshore module installations, tandem upending of pressure vessels, and turnkey transport of oversized industrial components.

Every project begins with engineering, not equipment. Load paths, ground bearing pressures, wind envelopes, and rigging geometry are resolved in our engineering office before a single crane ever rolls onto site.

03 — Capabilities

Four disciplines. One standard.

01

Tandem & Multi-crane Upending

Coordinated dual-crane vertical erection of pressure vessels, columns, and reactors up to 1,800 tonnes. Fully engineered load path from horizontal to vertical.

  • Crawler + mobile tandem lifts
  • Trunnion & tailing rigging design
  • Real-time load monitoring
02

Engineered Heavy Transport

SPMT-based transport of oversized loads through refineries, ports, and constrained sites. Route surveys, ground preparation, and clearance engineering included.

  • Self-propelled modular transporters
  • Route & bridge load analysis
  • Ro-Ro and quayside operations
03

Engineered Rigging Design

In-house rigging engineering — from lift plans and pad-eye design to spreader beams and custom lifting frames. FEA-verified, insurer-accepted, code-compliant.

  • ASME B30 & BS 7121 compliant
  • Custom spreader & lifting frames
  • 3D lift simulation & clash detection
04

Site Assessment & Method Statements

Pre-project assessments, ground bearing studies, and method statements accepted by tier-1 EPC contractors and international insurers.

  • Ground bearing & crane pad design
  • Method statements & HIRA
  • Insurer & MWS liaison
04 — The Operation

A vessel upending, step by step.

Scroll through the animation to see how a tandem lift transforms a horizontal pressure vessel into its final vertical position — hooks descend, slings tension, and the load rotates around a fixed trunnion.

05 — Field Experience

Two decades in the field.
Cranes, rigging, offshore, refineries.

From a crane operator in India (2005) to a LEEA Certified Appointed Person in Angola (2025) — every role climbed the ladder of lifting engineering. Photos below are from active field operations across three continents.

Full project references shared confidentially on request. All operations conducted under BS 7121 / LOLER / ASME B30 discipline.

06 — Sample Lift Plans

What we deliver. Ten worked examples.

These are the kind of lift plans we produce for real clients — crane selection, load charts, rigging calculations, risk assessment, and method statements. Every plan is signed off by a LEEA Certified Appointed Person under BS 7121, LOLER, and ASME B30 standards. Client names and locations redacted.
