SAFETY FIRST

2.0 SAFETY ISSUES

Read all instructions, warnings and cautions

carefully. Follow all safety precautions to avoid personal injury or property damage during system operation. Enerpac cannot be responsible for damage or injury resulting from unsafe product use, lack of maintenance or incorrect product and/or system operation. Contact Enerpac when in doubt as to the safety precautions and operations. If you have never been trained on high-pressure hydraulic safety, consult your distribution or service center for a free Enerpac Hydraulic safety course.

Failure to comply with the following cautions and warnings could cause equipment damage and personal injury.

A CAUTION is used to indicate correct operating or maintenance procedures and practices to prevent damage to, or destruction of equipment or other property.

A WARNING indicates a potential danger that requires correct procedures or practices to avoid personal injury.

A DANGER is only used when your action or lack of action may cause serious injury or even death.

WARNING: Wear proper personal protective gear when operating hydraulic equipment.

WARNING: Stay clear of loads supported by hydraulics. A cylinder,

when used as a load lifting device, should

never be used as a load holding device. After the load has been raised or lowered, it must always be blocked mechanically.

DANGER: To avoid personal injury keep hands and feet away from cylinder and workpiece during operation.

WARNING: Do not exceed equipment ratings. Never attempt to lift a load

weighing more than the capacity of the cylinder. Overloading causes equipment failure and possible personal injury. The cylinders are designed for a max. pressure of 350 bar [5,000 psi]. Do not connect a jack or cylinder to a pump with a higher pressure rating.

DANGER: Never set the relief valve to a

higher pressure than the maximum rated

pressure of the pump. Higher settings may result in equipment damage and/or personal injury. Do not remove relief valve.

WARNING: The system operating

pressure must not exceed the pressure rating of the lowest rated component in

the system. Install pressure gauges in the system to monitor operating pressure. It is your window to what is happening in the system.

CAUTION: Avoid damaging hydraulic

hose. Avoid sharp bends and kinks when

routing hydraulic hoses. Using a bent or kinked hose will cause severe back-pressure. Sharp bends and kinks will internally damage the hose leading to premature hose failure.

Do not drop heavy objects on hose. A

sharp impact may cause internal damage

to hose wire strands. Applying pressure to a damaged hose may cause it to rupture.

IMPORTANT: Do not lift hydraulic

equipment by the hoses or swivel

couplers. Use the carrying handle or other

means of safe transport.

CAUTION: Keep hydraulic equipment

away from flames and heat. Excessive

heat will soften packings and seals, resulting in fluid leaks. Heat also weakens hose materials and packings. For optimum performance do not expose equipment to temperatures of 65 °C [150 °F] or higher. Protect hoses and cylinders from weld spatter.

DANGER: Do not handle pressurized

hoses. Escaping oil under pressure can

penetrate the skin, causing serious injury. If oil is injected under the skin, see a doctor immediately.

WARNING: Only use hydraulic cylinders in a coupled system. Never use a cylinder with unconnected couplers. If the cylinder becomes extremely overloaded, components can fail catastrophically causing severe personal injury.

IMPORTANT: Hydraulic equipment must only be serviced by a qualified hydraulic technician. For repair service, contact the Authorized ENERPAC Service Center in your area. To protect your warranty, use only ENERPAC oil.

WARNING: Immediately replace worn or damaged parts by genuine ENERPAC parts. Standard grade parts will break causing personal injury and property damage. ENERPAC parts are designed to fit properly and withstand high loads.

3.0 DESCRIPTION

These swing cylinders are designed to swing 90° in a clockwise or counter-clockwise direction. They can also be used in straight clamping applications. Single-acting and double-acting swing cylinders are available.

Clamp arms are not supplied with cylinders. Clamp arms can be purchased separately or made according to the specifications on page 13.

4.0 PRELIMINARY INFORMATION

IMPORTANT: Failure to read and follow these instructions may lead to system malfunction or product failure, and could invalidate your warranty.

(1) High flow rates can lead to excessive cylinder speed which can cause cylinder damage. Hydraulic

pressure and cylinder speed must be adjusted to match the length of clamp arm. The clamping force also varies with the length of the clamp arm. Refer to page 2 for operating specifications.

(2) Flow controls with return checks should be used to reduce swing cylinder speed to the

recommended rate. The return checks help minimize back pressure that could lead to an unclamp malfunction on single-acting systems.

(3) When using single-acting swing cylinders, limit the return flow back pressure to 3,5 bar (50 psi)

maximum. Large diameter tubing (10 mm O.D. or larger) and flow controls with free flow return checks help minimize back pressure. Consult Enerpac for proper system design.

(4) Excessive return flow back pressure can also damage double-acting swing cylinders. Limit the

return flow back pressure to 42 bar (600 psi) maximum. Double-acting systems should be set up for a metered-in with reverse free flow in the clamp port.

(5) Clamping of the part should occur at the midpoint of the vertical travel. No clamping of part shall occur

while the swing clamp is turning. Clamp arm should freely travel during the 90° rotation (avoid contact with cutter heads, tools, etc.).

(6) Attaching clamp arm to cylinder plunger must be done according to the instructions on page 6.

5.0 MOUNTING SPECIFICATIONS

5.1 Mounting Threaded Body Cylinders

Threaded body cylinders can be threaded into a tapped hole, secured to the fixture using a mounting flange, threaded into the fixture and secured with a jam nut, or mounted through a clearance hole and secured with jam nuts. See illustrations below.

When a threaded body style swing cylinder is being installed in a fixture, the thread engagement should be no less than the thread engagement for the standard Enerpac mounting flange. If a cylinder is being mounted using just the lower portion of the threads, the engagement should be increased for additional support. See table below for minimum thread engagement.

5.2 Mounting Upper and Lower Flange Cylinders

WARNING: The fixture must be capable of withstanding 350 bar (5000 psi) hydraulic working pressure when the cylinders are manifold mounted.

0,01

Before a swing cylinder can be manifold mounted, the port screw plugs and copper gaskets must be removed.

The o-rings provided should be lubricated and installed in the counterbore around the port prior to mounting and bolting down the swing cylinder.

Be sure that the o-ring does not get pinched or damaged during mounting as leakage could result. To prevent leakage from the manifold mounting, provide a fixture mounting surface with flatness within 0,08 mm (0.003 in.) and a surface roughness not to exceed Ra 1,6.

6.0 INSTALLATION

These Swing Cylinders are designed so that you can set the position of the clamp arm after mounting the cylinder. If you need to change the rotation direction, do it before mounting the cylinder.

Change plunger rotation by lining up the letter on top of the plunger with the arrow on the side of the cylinder opposite the ports. To change rotation, refer to illustrations and follow procedure below. You will need a spanner wrench.

1. Position the arm on the plunger to provide a handle to grasp for moving the plunger. (a) Release the clamp arm bolt. (b) Remove the retaining ring and slide the clamp arm down the plunger until the top of the arm is 6 mm

(0.25") from the top surface of the plunger.

2. Place spanner wrench on bottom cylinder plug and turn the plug (facing you) counter-clockwise 4 turns. NOTE: Single-acting cylinders may need the bottom plug to be rotated more than 4 turns to help relieve

return spring tension.

3. Push down on the plunger and rotate it to line up the desired letter (L, R, S) with the arrow on the side of the cylinder.

4. Once the letter and arrow are lined up, pull the plunger up, turn the bottom plug backin (clockwise) 4 turns, and tighten firmly.

6.2 Attaching Clamp Arm

1. Remove the retaining ring from the top of the plunger.

2. Slide the clamp arm down over the plunger and use a pliers to push the retaining ring back onto the plunger groove. Orient the retaining ring so the retaining ring gap will face the back of the clamp arm. See illustration.

3. Move the clamp arm up until it is firmly against the retaining ring and in the desired position. While maintaining this position, torque the clamp arm bolt to specification listed below.

CAUTION: Inadequate torquing of the clamp arm bolt

could cause the arm to slip during operation. BE SURE TO USE QUALITY GRADE 8 (12.9 DIN 912) SOCKET

HEAD CAP SCREWS (supplied with standard clamp arms).

6.3 Arms for Upper Flange Body Style

To use the upper flange body style cylinders, you have to be sure that the contact bolt will clear the upper flange during operation. The clamp arm must be long enough for the contact bolt to clear the upper flange as the arm swings down. Clearance problems are most common when the final clamping position is at the side of the cylinder and the contact bolt must pass by the front or back of the upper flange as it swings down. You may need to use the longer, CAL Series clamp arm for these applications.

6.4 Hydraulic Connections

To make port connections, install fittings rated for 350 bar (5000 psi). DO NOT use thread sealant. Sealing is accomplished by using an o-ring on the fitting boss. Lubricate the o-ring prior to assembly. When designing your hydraulic circuit, consider the factors listed in PRELIMINARY INFORMATION on page 2. For more information about plumbing hydraulic circuits, see your Enerpac Catalog.

7.0 OPERATION

Swing cylinders rotate 90° during the first portion of the stroke, continuing without rotation for the final clamping stroke. The straight downward stroke is the clamping stroke of the cylinder. Clamping force must be applied only during the vertical travel, not during the swing motion.

CAUTION:

— If clamping force is applied during the rotation portion of the stroke, internal plunger damage will result. — To ensure maximum cylinder performance and safety; be sure all hydraulic connections, hoses, and

fittings are properly sealed and fully tightened.

— Be sure all items are rated to withstand system pressures. Under-rated components will not withstand

higher pressure. Using under-rated components will lead to equipment damage and possible personal injury.

7.1 Vent Plug

Single-acting cylinders have a vented plug on the left side of the cylinder when you are facing the hydraulic ports. To prevent entry of chips and coolant, the vent plug must not be removed. If the vent plug is subjected to a continuous coolant flood condition, attach tubing to the port using a BSPP fitting, and run the tubing to a non-contaminated area of the fixture.

7.2 Pressure and Flow Rate

Clamp arm length (L) determines operating pressure setting and flow rate.

See Operating Specifications — Maximum Flow Rate Chart on page 2 for clamp arm length, pressure setting and flow rate. Set operating pressure and flow rate according to the limits established by the length of the clamp arm. Do not exceed the load-to-length pressure ratios. As the arm length increases, the clamping force and maximum operating pressure are reduced.

CAUTION: It is very important that you use the correct pressure and flow settings. Operating

outside these limits will cause damage to the swing cylinder. Damage caused by exceeding rated pressure and maximum flow is NOT COVERED BY WARRANTY.

8.0 MAINTENANCE

Maintenance is required when wear or leakage is noticed. Occasionally inspect all components to detect any problem requiring service and maintenance. Enerpac offers ready-to-use Repair Parts Kits. Repair Parts Sheets are available with assembly drawing and parts list. Contact Enerpac.

IMPORTANT: Consult the Repair Parts Sheet for service information about correct assembly and disassembly. Incorrect maintenance and service such as wrong torque values may cause product malfunctions and/or personal injury.

1.0 WICHTIGE VERFAHRENSHINWEISE FÜR DEN EMPFANG:

Alle Komponenten auf sichtbare Transport-schäden inspizieren. Transportschäden sind nicht von der Garantie gedeckt. Werden solche Schäden festgestellt, ist unverzüglich das Transportunternehmen zu verständigen. Das Transportunternehmen ist für alle Reparatur- und Ersatzkosten, die auf Transportschäden zurückzuführen sind, verantwortlich.

SICHERHEIT GEHT VOR

2.0 SICHERHEITSFRAGEN

Alle Anleitungen, Warnungen und Vorsichtshinweise sorgfältig

durchlesen. Beachten Sie alle Sicherheitsvorkehrungen, um Verletzungen oder Sachschäden während des Systembetriebs zu vermeiden. Enerpac ist weder für Schäden noch Verletzungen haftbar, die durch einen fahrlässigen Gebrauch des Produkts, mangelhafte Instand-haltung oder eine unvorschriftsmäßige Anwendung des Produkts und/oder des Systems verursacht werden. Bei evtl. Fragen in bezug auf Sicherheitsvorkehrungen und Betriebsabläufe wenden Sie sich bitte an ENERPAC. Wenn Sie an keinerlei Sicherheitsschulungen im Zusammenhang mit Hochdruckhydraulikanlagen teilgenommen haben, fordern Sie von Ihrer Vertriebsund Kundendienstzentrale einen kostenlosen EnerpacHydraulik-Sicherheitskurs an.

Ein Mißachten der folgenden Vorsichtshinweise und Warnungen kann zu Geräteschäden und Verletzungen führen.

Mit einem VORSICHTSHINWEIS wird auf ordnungsgemäße Betriebs- oder Wartungsverfahren und –praktiken hingewiesen, um Schäden an den Geräten oder anderen Sachwerten bzw. deren Zerstörung zu vermeiden.

Eine WARNUNG verweist auf eine potentielle Verletzungsgefahr, die durch ordnungsgemäße Verfahren oder Praktiken vermieden werden kann.

Ein GEFAHRENSHINWEIS wird nur dann gegeben, wenn eine bestimmte Handlung oder die Unterlassung einer bestimmten Handlung schwere oder tödliche Verletzungen zur Folge haben kann.

WARNUNG: Beim Betrieb hydraulischer Anlagen geeignete Schutzkleidung und –ausrüstung tragen.

WARNUNG: Von Lasten fernhalten, die durch ein Hydrauliksystem abgestützt werden. Ein als Lastenhebegerät

eingesetzter Zylinder darf niemals als ein

Lastenhaltegerät verwendet werden. Nach Heben oder Senken der Last muß diese stets auf mechanische Weise gesichert werden.

GEFAHR: Zur Vermeidung von

Verletzungen während des Betriebs Hände und Füße von Zylinder und Werkstück fernhalten.

WARNUNG: Die zugelassene Nennleistung der Geräte nicht überschreiten. Keine Last zu heben versuchen, deren Gewicht das

Hebevermögen des Zylinders übersteigt. Überlastungen verursachen Maschinenausfälle und können zu Verletzungen führen. Die Zylinder wurden für einen max. Druck von 350 bar konstruiert. Keinen Heber oder Zylinder an eine Pumpe mit einer höheren nominalen Druckleistung anschließen.

GEFAHRENSHINWEIS: Das Überdruckventil keinesfalls auf einen höheren Druck als den

maximal zulässigen Druck der Pumpe einstellen. Höhere Einstellungen können zu

Geräteschäden und/oder Verletzungen führen. Nicht das Druckbegrenzungs-Ventil entfernen!

WARNUNG: Der Systembetriebsdruck darf den zulässigen Nominaldruck der Systemkomponente mit der niedrigsten Nennleistung nicht überschreiten. Zur Überwachung des

Betriebsdrucks sind Manometer im System zu installieren. Dies ist das Fenster zu den Abläufen im System.

VORSICHT: Beschädigungen am Hydraulikschlauch vermeiden. Beim

Verlegen der Hydraulikschläuche enge Bögen und Abknicken vermeiden. Der Einsatz eines

gebogenen oder geknickten Schlauchs führt zu einem hohen Rückstau. Starke Biegungen und Knickstellen schädigen den Schlauch auf der Innenseite und führen zu dessen vorzeitigem Ausfall.

Keine schweren Gegenstände auf den Schlauch fallen lassen. Starke Erschütterungen können Schäden an den im

Schlauchinnern verlaufenden Drahtlitzen verursachen. Ein Schlauch, auf den Druck ausgeübt wird, kann bersten.

WICHTIG: Hydraulische Geräte weder an den Schläuchen noch den Gelenkanschlüssen anheben. Dazu den Tragegriff oder eine andere sichere

Transportmethode verwenden.

Bedienungsanleitung

Schwenkspannzylinder

Metrisch 2,2 N und 5,6 N

L2058 Rev. C 03/12

VORSICHT: Hydraulische Geräte von Flammen und Hitzequellen fernhalten. Zu hohe Temperaturen

weichen Füllungen und Dichtungen auf und bewirken Flüssigkeitslecks. Große Hitze schwächt außerdem die

Schlauchmaterialien und –dichtungen. Zur Gewährleistung einer optimalen Leistung darf die Anlage keinen Temperaturen über 65°C ausgesetzt werden. Außerdem müssen Schläuche und Zylinder beim Schweißen vor Funkenschlag geschützt werden.

GEFAHR: Nicht mit unter Druck stehenden Schläuchen hantieren. Unter Druck austretendes Öl kann in

die Haut eindringen und schwere Verletzungen verursachen. Falls Öl unter die Haut gelangt, ist sofort ein

Arzt aufzusuchen.

WARNUNG: Hydraulikzylinder nur in einem gekopelten System verwenden. Niemals einen Zylinder

mit unverbundenen Kupplungen verwenden. Bei einer extremen Überlastung des Zylinders können

dessen Komponenten schlagartig bersten, was schwere Verletzungen hervorrufen kann.

IWICHTIG: Hydraulische Geräte müssen von einem qualifizierten Hydrauliktechniker gewartet werden.

Bei Reparaturarbeiten an die autorisierte ENERPAC-Kundendienstzentrale der jeweiligen Region wenden.

Zur Aufrechterhaltung der Garantie nur ENERPAC-Öl verwenden.

WARNUNG: Abgenutzte oder beschädigte Teile unverzüglich durch ENERPAC-Originalteile ersetzen.

Standardteile anderer Hersteller versagen und verursachen Verletzungen und Sachschäden. ENERPAC-

Teile werden so konstruiert, daß sie richtig passen und hohen Lasten standhalten.
