1. Proper usage
Usage:
The trolleys can be used for I-beams with plane flanges (such as IPE, HEA or HEB types) or beams with sloping flanges (such as INP-beams).
The possible width ranges are shown in the data tables.
The trolley is a rolling and geared chassis for attaching to lifting gear for use inside.
It is not suitable for continuous operation.
It is not suitable for use in rooms where there is a potential risk of explosions.
It is not suitable for use in aggressive atmospheres.
The unit should be installed if possible in a covered room. If it is installed outdoors a roof is to be provided or the unit is to be covered.
Modifications to the lifting gear are only permitted with our express consent in writing.
Refer to the technical data and function description.
Safety instructions
Operation and servicing must be left strictly to: authorized, trained personnel.
• Only install the trolley on girders whose load capacity has been checked previously.
• Do not install the trolley on tapered girders.
• Stops on the ends of girders must not be moved or removed.
• Do not transport personnel or allow personnel to be located in the danger area.
• Do not allow the load to swing.
• Do not stand under a raised load.
• Never reach into moving parts.
• Defects are to be rectified immediately by trained personnel.
• Never leave the load off the ground without supervision.
• Loads may only be raised vertically. Do not raise loads at an angle.
• Do not use the trolley to pull items out of other items, release them or drag them sideways.
• The trolley may only be used to push or pull the load.
• Do not exceed the load capacity set out in the technical data.
• Check the raceway width and adjust the distance between the chassis flanges using the figures in the table.
• The hand chain is only designed for moving the load attached to the lifting gear and must not be used for any other purpose.
• High strength parts such as the chain, hook and gear parts must not come into contact with free hydrogen, acids, alkalis, vapour or very
aggressive cleaning products. They may become brittle and fracture.
• Conduct a risk analysis before use and verify EC conformity.
• Working temperature: -10°C to +50°C.
The chassis chain (hand chain)
• is only designed for moving the trolley and must not be used for any other purposes.
• must not be used to attach a load.
• must not be drawn over sharp edges.
• must not be twisted.
• Before you use the trolley check that it is correctly mounted on the girder.
• Conduct a visual inspection of the rollers every day. Pay special attention to the lateral play between the raceway girder and the rollers.
• Check that the bolts are secure and that the traverse is secure.
Commissioning
Function description
The roller chassis may only be pulled on the load, the load hook or the load chain of the lifting gear.
The roller chassis is to be attached to a horizontal raceway girder.
The raceway girder must be flat and horizontal.
The chassis width may be adjusted by spacing to the relevant girder width.
The chassis is designed without a brake.
The attached load may be moved either by pushing or pulling the load (rolling chassis) or by pulling the hand chain (gear chassis).
The movement speed should be such that the load can be braked by the user at any time.
Assembly and installation of the trolley on the girder
The trolleys can be adjusted to various girder flange widths.
1. Establish the girder dimensions (M) (flange width).
2. Check conformity with the data sheet.
Installation instruction
1. Measure the width of the beam
2. Assemble the trolley with the required number of spacer washers on the carrying axle between the trolley side plates so that that there is a
slight clearance of F mm each side between the trolley's wheel flanges and the beam width. Make sure to have the same number of washers on
each side of the lifting ring so the load is centered There must always be at least one washer on the inside and outside of each trolley side plate
3. The remaining washers need to be placed at the outer side of the trolley side plate opposite to the mounting plate or chain wheel.
4. Fit the trolley on the beam and tighten the mount-plate by hand and make sure all wheels roll on the beam. Tighten the nuts of the mounting
plate with a wrench
5. Load the trolley and move it over the beam to check it runs smoothly. If the wheel flanges are too far from the beam or grinding against it, read-
just the trolley by removing or adding washers between the trolley side plates.
Commissioning
Ensure that the chains are correctly positioned; they must not be twisted and must hang freely.
Always refer to the operating manual of the lifting gear you are using.
The open meshing on the drive unit should be greased.
Function test:
Carefully move the chassis to the limit position and check the position of the limit stops.
