AC Crane Maintenance supplies, installs, commissions, repairs and supports industrial wireless remote control systems for overhead cranes, gantry cranes, electric hoists and specialised lifting equipment throughout South Africa. From new Vectra VR4, VR6 and VR8 systems to repairs and replacement of existing crane remotes, we provide practical control solutions built around the application.
Wireless crane controls allow the operator to move to a suitable operating position rather than being physically tied to a pendant cable. This can improve visibility, positioning and freedom of movement while reducing the maintenance associated with travelling pendant cables.
The operator can select a suitable position with improved visibility of the load and lifting area.
No pendant cable physically ties the operator to one position alongside the crane.
Correctly configured controls can provide intuitive crane movement and accurate load positioning.
Removing a travelling pendant can eliminate pendant cable wear and associated mechanical damage.
An older crane does not necessarily need a complete electrical replacement to benefit from wireless control. AC Crane Maintenance can assess the existing crane controls and determine the correct method of integrating a new industrial radio remote system.
Different cranes require different numbers of control functions. We specify the remote around the crane and the operating requirement rather than simply supplying a generic radio system.
A compact and cost-effective wireless control solution for applications requiring fewer motion commands.
Suitable for many standard overhead and gantry crane applications requiring hoist, cross travel and long travel control.
Provides additional control positions for cranes requiring auxiliary, selection or specialised operational functions.
A wireless crane remote can do considerably more than basic crane movement. Depending on the crane control architecture and operational requirement, additional functions can be engineered into the system.
Selection between individual hoists or combined operation can be engineered into suitable multi-hoist crane systems with the required control interlocking.
Where the crane design permits, specialised control logic can be used for coordinated lifting applications requiring more than one hoist or controlled function.
Auxiliary buttons can be allocated to crane warning devices such as a siren or audible warning system where required.
Additional functions can be assigned to auxiliary crane equipment such as cable reeling systems where required by the installation.
Remote commands can be incorporated into the crane's control architecture with suitable electrical interlocking and control logic.
Additional control functions, selectors and delay requirements can be assessed and configured around the specific application where technically suitable.
Already have another make of industrial radio remote on your crane? AC Crane Maintenance is not limited to one wireless remote brand. We troubleshoot, repair, replace, supply, install and commission a wide range of crane remote control systems, subject to parts, system condition and technical support availability.
Assessment and repair of damaged or malfunctioning transmitters, receivers and associated crane control components where practical and parts are available.
Replacement transmitters, receivers and complete remote systems can be supplied according to the existing system or converted to a suitable alternative.
Our crane technicians can install and integrate wireless control systems into new or existing crane electrical controls.
Keeping an old radio system operating is not always the most economical solution. If replacement transmitters, receivers or spare parts have become difficult or expensive to obtain, AC Crane Maintenance can assess conversion to a modern wireless remote control system.
Where technically suitable, the existing radio receiver can be removed and a new receiver integrated into the crane control circuit while retaining the required crane movements and safety functions.
AC Crane Maintenance records relevant information for wireless remote systems supplied by us against the crane or application. This helps us identify the supplied system when future support or replacement equipment is required.
If a transmitter is damaged or lost, having the system information available can make identifying and preparing the correct replacement substantially easier and help reduce unnecessary crane downtime.
The number of buttons is only one part of selecting a remote. The complete crane, electrical control system and operating requirements must be considered.
Hoist, cross travel, long travel and any additional auxiliary functions.
Single speed, multi-speed or VSD-controlled movements and the required command arrangement.
The available electrical supply and control voltage at the crane receiver installation.
Indoor, outdoor, dust, moisture, heat and other environmental considerations.
Current pendant, contactor, PLC or control architecture and how the radio must integrate.
Siren, selectors, magnets, grabs, cable reels or other auxiliary crane equipment.
Single-hoist, twin-hoist or specialised multiple-hoist applications.
Whether you need a transmitter, receiver, complete system, repair or full conversion.
Wireless control for single-girder and double-girder overhead travelling cranes.
Remote operation for indoor and outdoor gantry crane applications.
Radio control for monorail and overhead crane wire rope hoist applications.
Compact wireless systems for chain hoists and lighter industrial lifting applications.
Replace old pendant or obsolete radio control systems during crane upgrades.
Custom radio-control requirements can be assessed around the machine and operating application.
A crane remote is part of a larger control system. Correct installation requires more than simply connecting a receiver to a few wires. The crane functions, contactors, VSD inputs, limits, emergency stop circuit and required interlocking must be considered as part of the complete installation.
The remote system must be correctly integrated into the crane's applicable control and stopping architecture.
Opposing or incompatible commands must be appropriately controlled through the crane's electrical design.
Wireless operation does not replace crane limits, load protection or other required crane safety systems.
A radio-control fault does not automatically mean the transmitter is defective. The problem may be in the transmitter, receiver, receiver power supply, crane control circuit, wiring, relays, contactors or another part of the crane system.
Assess physical condition, controls, receiver and available system information.
Determine whether the fault is radio-related or elsewhere in the crane control system.
Recommend the practical repair, replacement component or complete conversion.
Verify the required crane functions and system operation after work is completed.
