The overload switches are force or weight sensing devices although they have no indicator as part of their system. Instead they shut off power when they register an overload condition, or they activate alarm lights, buzzers or klaxons to warn of impending overload.

Dillon Dyna-Switch systems are a reliable, low cost way to control forces and prevent overloads. They can be used in automation controls, acting as scales.
They can be used on cranes, hoists and elevators--not only to shut off power when an overload condition exists, but they can also be set to operate lights, buzzers or klaxons to warn of an impending overload. Like 24-hour sentinels, they can operate in normal or extreme environments.

The heart of the system is a force beam which operates in tension or compression. Seven different load capacities are available. Switch and physical connection options are listed. Each beam can accomodate from one to four switches which can be set to operate as many as four different switching functions or combinations including slackline detection.

Switch settings are normally made to custom specifications at the factory where force standards for such settings are available. All Dyna-Switch force beams and attachment fittings have an ultimate safety factor of 5:1 (4.5:1 for metric capacities). In addition, all models have an overload stop or bolt to provide extra protection to the measuring ability of the Dyna-Switch force beam.

Cranegard^® Model CGS

Clamps on cables for wire rope hoist, elevator and crane overload prevention and slackline detection. Installs in minutes with screwdriver and Allen wrench.

Installation is simplicity itself. Cranegard^® is clamped directly on hoist or crane wire rope quickly without severing rope or interrupting service. Up to four switches (two, if option C) can be furnished. Switch is actuated immediately when pre-set load limit is exceeded.

Switch settings are normally made to custom specifications at the factory where force standards for such settings are available.

Installs by clamping to cables. No need to cut the cable. Use for slack line detection. Protect against overloads to wire rope on hoists, elevators and cranes.
