Crane Manufacturing, Supply & Installation South Africa

Engineered, Manufactured & Installed for Real Industrial Performance

At AC Crane Maintenance, we design, manufacture, supply, and install complete overhead crane systems built for demanding industrial environments.

We don’t assemble generic kits – we engineer cranes based on actual operating conditions, structural requirements, and long-term performance expectations.

Engineered and manufactured in accordance with applicable SANS standards and international best practices, including ISO-aligned quality management systems.

Complete Turnkey Crane Systems (Design → Build → Install)

We deliver full crane systems from concept to commissioning, including:

• Mechanical design and engineering calculations
• Structural fabrication (girders, end carriages, platforms)
• Runway beam design, alignment, and installation
• Hoist selection and integration (rope or chain)
• Electrical control panels and VSD systems
• Safety systems (load limiting, limits, anti-collision)
• Load testing, commissioning, and certification

One contractor responsible for the entire system = no gaps, no mismatches, no excuses

Engineering & Design Considerations

A crane is not just a beam and a hoist – it is a dynamic load system interacting with your building and production.

Every crane we design considers:

Load & Duty

• Rated capacity (SWL)
• Duty classification (light, medium, heavy / M-class)
• Frequency of lifts and operational cycles
• Impact and shock loading

Structural Forces

• Wheel loads transferred to runway beams
• Horizontal forces during braking and acceleration
• Skewing forces due to misalignment
• Load distribution across girders and end carriages

Geometry & Layout

• Span and lifting height
• Hook approach limits
• Headroom restrictions
• Runway alignment and tolerances

Environment

• Indoor vs outdoor operation
• Dust, heat, corrosion, and moisture
• Mining and heavy industrial conditions

This is where most cheaper cranes fail – they are not designed for real conditions.

In-House Manufacturing

All structural components are manufactured in-house under controlled conditions.

We manufacture:

• Single and double girder crane beams
• End carriages and wheel assemblies
• Gantry crane structures
• Jib crane arms and columns
• Walkways, platforms, and access structures

Fabrication includes:

• Controlled welding procedures
• Dimensional accuracy and alignment checks
• Fitment of wheel assemblies and drive systems
• Preparation for electrical and mechanical integration

No outsourcing means:

• Better quality control
• Faster turnaround
• Full accountability

Crane Types & Applications

We manufacture and install:

Overhead Cranes

• Single girder (light to medium duty)
• Double girder (heavy duty, higher capacity)

Gantry Systems

• Full gantry cranes
• Semi-gantry cranes

Jib Cranes

• Pillar-mounted
• Wall-mounted

Monorail Systems

• Straight or curved systems
• Integrated into production lines

Used across:

• Mining operations
• Manufacturing plants
• Steel and fabrication workshops
• Warehousing and logistics
• Engineering environments

Electrical & Control Systems

Most crane failures are electrical – not structural.

We design systems that ensure reliability under real conditions:

• Custom-built control panels
• VSD-controlled lifting and travel
• Dual-speed or variable speed operation
• Wireless remote systems
• Emergency stop and fail-safe circuits
• Load limiting and protection systems

Why this matters:

• Smooth starts and stops reduce mechanical shock
• Better positioning improves productivity
• Reduced stress extends component life

A good crane with a bad control system = constant breakdowns

Installation, Alignment & Commissioning

Installation is where most crane problems are created – not manufacturing.

We focus heavily on:

Mechanical Installation

• Correct positioning of end carriages
• Alignment of runway beams
• Wheel-to-rail contact accuracy
• Torque settings on all structural connections

Electrical Commissioning

• Functional testing of all controls
• Safety circuit verification
• Limit switch setup
• Load limiting calibration

Final Commissioning

• No-load testing
• Functional movement checks
• Full load testing
• Certification and handover

Poor installation leads to:

• Skewing cranes
• Wheel wear
• Gearbox strain
• Early failure

Load Testing & Legal Compliance

Load testing is required to prove that the crane can safely handle its rated load.

Required when:

• New crane installation
• After major repairs
• After structural modifications
• After relocation
• After hoist replacement

Standards & Regulations:

• Occupational Health and Safety Act
• Driven Machinery Regulations
• SANS 10375 (inspection and testing of cranes)

Testing and certification must be carried out by:

• A registered Lifting Machinery Entity (LME)
• A certified Lifting Machinery Inspector (LMI)

This is not optional – it is legal compliance.

What Happens When Cranes Are Built Wrong

Poorly designed or installed cranes result in:

• Continuous misalignment and skewing
• Rapid wheel and rail wear
• Gearbox and motor overload
• Rope damage and poor spooling
• Frequent breakdowns
• Safety risks to operators

Cheap cranes are expensive over time.
