Installing the trolley power supply

 

If the trolley towing arm has not been installed yet, continue here. Otherwise, skip this section.

The trolley towing arm is installed above the hoist panel. It pulls the electrical cables for the trolley power supply (festoon cable system or energy chain) and the cross-type limit switch of the trolley travel limit switch back and forth parallel to the trolley.

The trolley towing arm must be installed differently, depending on the main girder (I-beam or box girder) and the type of power supply (festoon cable system or energy chain).

 

Mounting the trolley towing arm

Only with trolley D, DA or DB and energy chain

This section only applies if a trolley of construction D, DA, or DB is connected to an overhead travelling crane with an energy chain.

 

The component parts of the trolley towing arm are enclosed loose and must be assembled.

*   Screw the square tube to the mount using two pipe clamps. 15 Nm.

 

 

Rectangular pipe clamp

Individual components of the energy chain

Pipe clamp

Carrying tube

*   Screw the carrying tube with pipe clamp and rectangular pipe clamp onto the vertical square tube (trolley towing arm). 15 Nm.

*   Fasten the individual components of the energy chain (deflection bracket and connection element) with bolts and SL safety clip to the carrying tube.

 

 

Cable ties

Flat cable

Connection element

Energy chain

*   Lead through the flat cable from the energy chain and guide in a curve around the deflection bracket.

*   Fasten the flat cable with cable ties to the upper section of the deflection bracket.

*   Insert the energy chain into the connection element and click into place.

 

 

 

 

Only for trolley DQA
and energy chain

This section only applies if a trolley of construction DQA is connected to an overhead travelling crane with an energy chain.

 

The component parts of the trolley towing arm are enclosed loose and must be assembled.

 

 

Mounting plate

Carrying tube

*   Insert the carrying tube from below into the trolley frame.

*   Screw on the mounting plate with a hexagonal head screw M8 and hexagonal nut.

*   Insert the carrying tube between the mounting plate and the trolley frame.

*   Tightly screw on the hexagonal nuts. 25 Nm

 

 

Rectangular pipe clamp

Carrying tube

Pipe clamp

Individual components of the energy chain

*   Screw the horizontal carrying tube with pipe clamp and rectangular pipe clamp onto the vertical carrying tube (trolley towing arm). 15 Nm.

*   Fasten the individual components of the energy chain (deflection bracket and connection element) with bolts and SL safety clip to the square tube.

 

 

Cable ties

Flat cable

Connection element

Energy chain

*   Lead through the flat cable from the energy chain and guide in a curve around the deflection bracket.

*   Fasten the flat cable with cable ties to the upper section of the deflection bracket.

*   Insert the energy chain into the connection element and click into place.

 

 

 

 

Only for an overhead travelling crane with a festoon cable system

The trolley towing arm is fastened pre-installed to the C-rail system and must be fitted to the trolley.

For trolleys with trolley travel limit switches: the trolley travel limit switch is already completely installed.

 

 

Trolley towing arm

Marking

 

*   Attach the installed trolley towing arm to the end carriages.

In most cases, the end carriage has a marking at which the trolley towing arm is to be attached. The switching point of the trolley travel limit switch is already adjusted for this position and the cable lengths correspondingly adapted.

*   Screw the trolley towing arm tightly with the threaded bracket and rib nuts (2x).

Installing the cross-type limit switch on the trolley towing arm

Only with cross-type limit switch

This section only applies if the wire rope hoist has a cross-type limit switch in the trolley travel direction.

Where and for which travel limit the cross-type limit switch is designed is specified on the wiring diagram.

 

Installing the cross-type limit switch

Warnung Vorsicht

Danger due to malfunction!

If the cross-type limit switch is screwed on too tightly, the parts on the inside can become jammed and no longer function properly.

The tightening torque of 3 Nm must be strictly observed.

 

Locking washer

Hexagonal nut

Fillister-head screw M5x50

Mounting bracket

*   Screw the mounting bracket onto the cross-type limit switch with the fillister-head screws M5x50 (2x).

*   Screw on the mounting bracket using locking washers and M5 hexagonal nuts (2x). 3 Nm.

 

 

Installing the cross-type limit switch

The cross-type limit switch is normally installed on the trolley towing arm.

 

Pipe clamp

 

Cross-type limit switch

 

*   Turn the cross-type limit switch to position 0.

*   The position of the cross-type limit switch is marked with an arrow that can be rotated further, depending on the switching state.

*   Move the cross-type limit switch onto the square tube in such a way that the switching lug activates the cross-type limit switch.

*   Screw in the cross-type limit switch with pipe clamps (2x) tightly. 15 Nm.

 

 

Connecting the cross-type limit switch

*   Route the connection cable (round cable or flat cable) from the cross-type limit switch to the panel.

*   Route the connection cable with cable fitting into the panel.

*   If necessary, connect the connection cable to a coupler plug or connector.

*   Fasten connection cable with cable ties, cable grips and adhesive clips.

Connectors and coupler plugs

Connection cables

Cable ties

*   Lay the connection cable leading from the energy chain along the square tube to the hoist panel.

*   Fasten the connection cables neatly separated with cable ties.

*   Plug the connector and coupler plugs into the hoist panel, or guide the connection cables through cable fittings and into the hoist panel.
