Scales/Overload Devices

scales_overhead_devices
Scales & Overload protection serve two important goals; improved safety and increased efficiency. Crane scales and overload devices allow operators to know how close the load they are lifting is to maximum capacity and if a dangerous situation exists if a load is over capacity. They also increase efficiency as they allow operators to maximize the work they accomplish during their shift.

The inherent efficiency of the crane scale guarantees its continuing popularity. A correctly installed crane scale lets operators accomplish two things at once; move materials and simultaneously gather accurate weigh data or inventory information.

The ideal crane scale must be more than accurate and the following scales are not only accurate, but easy to read and unquestionably safe for overhead operation.

Overload Devices

Overload devices have proven to be an important step towards overhead crane safety. They provide operators with vital information, letting them know if the load that they are lifting is at a critical capacity. Overload devices can be wired in a number of ways. The most common techniques for setup is to activate a warning lamp/horn or even to shut off the signal for lifting when a load is too large. Placing the overload switch in the “up” circuit allows a load to still be lowered in the event that it becomes overloaded, even though it will not raise.

dillon_cranegurard

Dillon Craneguard

Craneguard force control switches provide crane overload protection and slack-line detection. They are an effective and affordable warning system that is easy to install. They clamp directly on hoist or crane wire rope, there is no need to cut rope or interrupt service. They can be wired to activate a warning light or audible alarm or interrupt a crane’s power source when cable loads reach specified levels. Craneguard is also versatile as each system can include from one to four switches, each with a preset load limit.

straightpoint_loadpin

StraightPoint LoadPin Load Sensor

If a pin exists within a defined load path or can be fitted to experience a force, then a StraightPoint LoadPin can be installed to monitor that load.  Example applications include sheave pins and pins for dead end fittings.  The load measuring pin senses the force applied across it, via strain gauges installed within a small bore through the center of the pin.  Two grooves are machined into the outer circumference of the pin to define the sheer planes, which are located between the forces being measured.

They are machined from high tensile stainless steel and are normally supplied complete with an anti-rotation plate.  Each LoadPin is built to exacting standards and are suitable for use in exposed situations.  They are proof loaded to 150% of the normal rated load.
