IEHC supplies control handles for real industrial applications, including crane motion control and hydraulic hatch operation. The current range includes XAC-A series handles, COP-ER rainproof crane switches and COP hydraulic control boxes.
We review operating functions and electrical requirements before model selection, helping ensure that the handle layout and contacts correspond with the equipment control circuit.
Pendant control of lifting, lowering, trolley travel and bridge movement from a practical operator position.
Local up/down and optional travel commands for chain or wire-rope hoist systems.
Spring-return open/close control for hydraulic hatch and cover systems.
The terms often overlap. Selection should focus on the mounting method, number of commands, contact arrangement, electrical rating, enclosure protection and how the operator will hold or access the device.
Compare the required number of buttons, functions, contact logic, enclosure style and application. XAC models suit multi-button handle control, while COP models include crane pendant and hydraulic control-box arrangements.
No enclosure should be selected by name alone. Confirm the required ingress protection and describe rain, dust, temperature, washdown and cable-entry conditions.
Available customization depends on the model and quantity. Provide a function list or wiring diagram, button legends, control voltage and contact requirements for review.
Record the current model, button functions, number and type of contacts, control voltage, cable conductors, enclosure dimensions and wiring diagram. Do not replace a pendant based only on appearance.
