Crane load pins
JF Strainstall’s crane load pins can be incorporated easily and economically into cranes by replacing any existing load bearing pins.
All JF Strainstall load pins are manufactured from high tensile stainless steel and are environmentally sealed. We can also supply a complete crane weighing/overload system with the addition of a display/indicator.
Our standard range of load pins vary in capacity from 5 to 1,000 tonnes, however most load pins are manufactured to meet each customer's specific dimensional requirements.
Our load pins can be fitted into bottom blocks, lifting sheaves, compensating beams, under barrel bearings and many other locations depending on crane layout.
Benefits of crane load pins:
- Easy to install/retrofit
- Manufactured from stainless steel
- High levels of environmental protection
- Hazardous area load pins available
Industrial load pins
JF Strainstall's industrial load pins perform in conditions of extreme temperature, abrasive dust, moisture and vibration.
Designed to withstand harsh environments and resistant to the effects of metal fatigue, our industrial load pins hold up against repeated cyclic loads. Easily incorporated into the load path they are a simple replacement to existing load bearing pins. Capacities available range from 5 to 1,000 tonnes and are usually manufactured to meet customers' specific dimensional requirements.
Benefits of industrial load pins:
-
Easy to retrofit
-
Manufactured from high tensile stainless steel

JF Strainstall-bondura load pins
The revolutionary JF Strainstall-bondura® load pin eliminates play and ovality during operation, simultaneously providing intelligence and wireless capabilities.
While a certain amount of tolerance is required during the installation and extraction of a load pin, this often leads to issues during operation as it allows the pin to move during its lifetime cycle as a result of heavy loads and vibrations.
This movement causes ovality, which though repairable, is costly and often results in operational down time.
The JF Strainstall-bondura® is designed to overcome such wear and tear. Innovative cone sleeves, with corresponding tapering, expand on the pin upon tightening with an agreed torque value, securely fixing the load pin while still allowing for the required tolerance for installation and extraction.
The JF Strainstall-bondura® load pin eliminates play during operation, while still providing an accurate means of load monitoring.
• Unique load pin design eliminates tolerance during the operational
• Long term, six months plus data logging available
• Cabled mV/V or 4-20mA outputs available
• Wireless SmartLoad® variant available
• Strainstall-bondura® load pins are DNV GL type approved and have ABS PDA certification
• The SmartLoad® wireless devices are all available in Zone 1 and Zone 2 hazardous area variants with ATEx. IECEx and North American/Canadian Hazloc certification.
• Eliminate play and ovality, reducing lifetime maintenance costs
• Notification if the pin needs replacing
• Extended battery life of over six months
• Reduces NPT
