Load pins are sometimes referred to as force sensing clevis pins, lifting pins, weight pins, force pins, or shear pins but they are all the same in that they are all strain gauge transducers that measure weight. Our load pins are custom designed to our customer’s requirements. Load pins will typically replace the sheave pin of a lifting device. Pin loading must be in one direction only or side loading will occur and reduce pin load accuracy. To this end, keeper plates are often employed to keep the force pin aligned properly.

Easily convert a regular cabled load pin to wireless load pin with external 2.4Ghz wireless transmitters units in the following sizes:
T24-ACM-SA powered by 2 D cell batteries and provides the longest run time
T24-ACMi-SA powered by 2 AA cell batteries
T24-ACMm-SA powered by an external 3V DC supply
Capture your wireless signal directly to a PC via the T24-BSu USB base station receiver and display your data on the free T24LOG100 software.
Wirelessly connect to a PLC using the WL-T24-AOi analogue output.
Configurable analog outputs of 0-10 V, 0-5 V, 4-20 mA, 0-20 mA, ±10 V, ±5 V
>Wireless range of up to 800 m (2,600 ft) for the T24-AO1i industrial version & up to 100 m (330 ft) for the T24-AO1 desktop version
See Process Controls WL-T24-AOi for more details
Our wireless load shackles are based on the industry standard Crosby shackle and come in capacities ranging from 8.5t to 55t. Equipped with clip lock pin for fast assembly and dissassembly. Our 2.4Ghz wireless transmitters can provide a open field range up to 2000 ft at 3m height and can be display on a single channel or multi-channel hand held receivers.
External indicators can also be connected to the force pin via 4-pin military style quick-disconnects. This allows for easy disconnection and reconnection from the weight pin should the shear pin ever need to be moved, repaired, or stored. Quick disconnect cable comes in 10 ft, 20 ft, and 50 ft lengths.
Tension measurement can be displayed by an indicator via wired connection (see wired digital indicator). The cable connection between the shear pin and display can be a seal-over hard connect. This is suitable for installations where the load pin is not expected to be disconnected from the indicator. Please specify how much home run cable is required.
The recommended indicator for tension applications is the M2000 which provides for multi-point calibration to improve accuracy. If the crane is located outside, the M2000 should be purchased in a NEMA enclosure (see left photo) to protect against dust and water. Various enclosures are available (see below images) and more details about the M2000 are available in the indicators website.
The M2000 is available with a setpoint option card. These are overload detection and protection devices. Setpoints utilize solid state relays that can be used to trigger alarms or switch devices (i.e. motors) on or off at specified weights. When ordering the Setpoint option the type of device (AC or DC) being switched must be specified. Setpoints are frequently used in digital hanging crane scale applications.
The M2000 can be loaded with a special program that allows a hanging crane scale operator to adjust the indicator for multiple “Parts of Line”. The program is configurable for one to twelve parts of line and the software will be provided free of charge when needed with the purchase of an M2000 indicator and a crane scale dynamometer.
Remote score boards are often referred to as “remote displays”. This type of display must be used in conjunction with a digital indicator equipped with a serial output. The remote display mirrors what is displayed on the weight indicator. They are used in applications where weighing information needs to be seen at a distance from the indicator. Score boards are available in 2″ (50 ft visibility), 4.5″ (250 ft visibility) and 6.5″ (300+ ft visibility) lettering.
We can supply 4-20 mA ouput versus standard mV/V signal. The design incorporates a load cell shield connection and polarity insensitive current loop connections. It is not susceptible to damage from shorting loop leads together or to ground during operation and is specifically designed for ESD hazardous environments. These converters are ideal for systems that require a PLC.
Since 1981, Massload Technologies has been engaged in the design and manufacture of strain gauge load cell transducers, electronic instrumentation and scale products for industrial weighing. Today, Massload is Canada’s only VCAP certified load cell manufacturer and has become a leading solutions provider of custom engineered load cells and weigh scales, supplying industrial customers across North America and beyond.
