Proportional Modules

Sure Grip Controls has just released our new speed control switches. These modules come in two versions, a Variable Voltage module and a PWM Driver Module. Applications include speed control for feed rollers, rotary grapples, grab arms, hydraulic cylinders and motors.

These Proportional Controllers are perfect where simple control is needed to improve operator control or to just reduce damaging pressure spikes.

Both modules are designed to be used with our trigger, new Flex Buttons or Rocker style faceplate.

Bushing Adapters
Sure Grip Handles use an adapter bushing that reduces installation time and simplifies mounting the handle onto the joystick.

Adapter Bushings are ordered separately from the handle and are available with internal threads that range in size from 10mm to 14mm.

Sure Grip Handle Adapter Bushings

Select the correct size adapter bushing from the chart above. The unthreaded bushing comes predrilled with a 1/4″ (6mm) hole that can be drilled and tapped for custom applications.

If a special bushing is required, please call the factory as we have numerous special adaptor bushings available.

Rocker Kit

Sure Grip Control Handles are supplied with buttons bonded to the overlay that directly activate the switches. A Rocker Cover Kit is available that contains two styles of rockers and a small bottle of adhesive. The rocker permanently mounts across 2 horizontal or vertical buttons.

Installation Tips
Step 1: Place the Rocker Cover onto a pair of buttons, ensuring that the buttons locate properly into the recesses on the back side of the Rocker. Test the action to ensure that the buttons operate freely and the Rockers provide the desired feel for the operator.

Step 2: Remove the Rocker and apply a drop of the adhesive to the top of the button and inside of the Rocker recess. Press the Rocker onto the buttons and hold for 1 minute to allow the adhesive to set. Check the action again to ensure that the switches operate correctly and then leave for 2 hours before using. Once a Rocker is glued to the embossed overlay it will be impossible to remove.

Toggle Switches

Sure Grip handles can have the momentary button switches replaced with an on/off toggle or push on/push off switches in any of the faceplate locations. Some of the optional switches are shown on the accessories parts page.

Consult Factory for details.

“In-Line” Diode Pack

The Sure Grip In-Line Diode Pack fits all handles or wiring harnesses to protect switches against destructive voltage surges. The In-Line Diode Pack provides efficient surge suppression protection for your control handle to ensure maximum switch life. Simple solder connections ensure trouble-free life and allow the Diode Pack to be installed anywhere on the wiring harness. A tough two piece molded case protects the diode board and makes installation quick and easy. Diode Boards are furnished with diodes to protect up to 12 switches. Special diode board configurations can be supplied that will operate a diverter valve or replace other relay logic. Consult factory for details.

Model DP-12W Wired Diode Pack

Case: measures 1″ x 1″ x 4.5″ long
Diodes: 2 amps continuous, 60 amps surge
Wire Size: 18 – 24 gauge, stranded
Model DP-12: for up to 12 switch functions
Model DP-03: for up to 3 switch functions

Installation Notes:
Diodes must be installed to protect switches from damaging inductive kickback produced by solenoid or relay coils when the switch is released (turned off).

The Diode Pack would typically be installed in a convenient location on the cable leading from the control handle. Being careful not to cut any of the wires, remove 3 1/2″ of the outer jacket from the cable. Identify which wires are from the switches and lay them onto the circuit card. Mark the wires where they will be attached to the terminal posts.

Strip about 1/4″ of insulation from the wires where they are marked. Insert the wired into the terminal posts and solder. (You can lightly crimp the wire into the terminal to help hold it in place while soldering.)

Connect the ground lead to complete the installation.

10 Button Keypad

Sure Grip 10 Button Keypads provide extra switching functions to control computer, PLC or power relays.

Sure Grip Keypads fit the “L” Series Handles and are easily mounted to the handle with the wiring routed through the handle.

Wire is foil shielded to eliminate unwanted interference with signal-level switching.

Sure Grip Keypads offer comfortable, compact and durable multi-function switching options for all forestry and construction applications.

Switches: – Electrical: 250 ma @ 24 VDC – Mechanical: 10 million cycles Housing: – High Impact ABS Wire: – standard 10′ @ 24 gauge routed through the handle case Operating Force: – 250 grams, snap action

Note: The buttons closest to the handle are always the “B” buttons.

Installation Notes:
When Keypads are ordered with handles from the factory, they will be shipped already installed on the handles themselves. If ordered separately, the installer will need to drill out the mounting holes and wire hole in the handle case.
