MEEC TOOLS 013933 Hydraulic Workshop Crane

Safety Instructions

Always check the product before use. The product must only be operated and loads lifted or lowered when the user has full supervision of the product and the work area. Check that all welded joints are free from cracks and that all bolted joints are correctly tightened. Check that the level of the hydraulic fluid is correct and that there is no leakage. Only use the product on a level, hard surface and ensure that it is free to roll during lifting and lowering. Lower the load to the lowest possible position before moving the product. Be very careful when moving the product with a lifted load. Make sure that the load cannot start to swing out of control. Never work under a load hanging only from the product. Make sure that an uplifted engine is correctly mounted on a suitable stand or on all the brackets in the vehicle. Do not overload the product. Always observe the permitted maximum load in each given arm position. Lower the load slowly and carefully. Failure to follow all the instructions and safety instructions can lead to the risk of serious personal injury and/or material damage. It will also invalidate the warranty.

The Workshop Crane Works at the Following Heights

Description

Hydraulic workshop crane with swivel lifting hook and retractable lifting arm with four alternative lifting positions (max 250, 500, 750 and 1000 kg). The crane has six wheels for greater stability and safety, and is foldable for easier storage.

Assembly

NOTE: Two persons are required for assembly.

Study the supplied assembly details before assembly. Dimensions and number are specified in the list of assembly parts. Check that all the parts and assembly parts are included. Assemble the product from the lowest parts and up. Assemble the product on a level surface, otherwise the assembled product can be skew and result in a risk of personal injury and/or material damage.

Hydraulic system bleeding: After assembly, the hydraulic system must be bled to remove any air that may have entered during transport.

1. Open the bleed valve by turning it anticlockwise with the piston upright (as it is installed in the product).
2. Hold the end of the hydraulic piston and pump several times with the pump handle until the resistance no longer feels "spongy".

Step-by-Step Assembly

1. Fasten the two larger rear caster wheels (No. 19) on the Base structure with Bolts (No. 18), washers (No. 17), spring washers (No. 4) and nuts (No. 5) (Face bolts up when installing).
2. Fasten the smaller two caster wheels (No. 8) on the Base structure with Bolts (No. 1), bush (No. 3), spring washers (No. 4) and nuts (No. 5).
3. Fasten the remaining larger two caster wheels (No. 2) on the front legs (No. 6, 7) with Bolts (No. 1), bush (No. 3), spring washers (No. 4) and nuts (No. 5).
4. Slide the legs (No. 6, 7) into the front of the base (No. 20).
5. Fasten the guide plates (No. 16) to the base (No. 20) and front legs (No. 6, 7) with bolts (No. 15, 14), washers (No. 9) spring washers (No. 4, 10) and nuts (No. 11). Lift one side of the base to align the hole on the frame to the hole on each front leg (No. 6, 7), then insert the Ring Pins (No. 13) into the hole, and insert the Cotter-pin (No. 12) into the hole of the Ring Pins.
6. Use Bolts (No. 15) and Spring washers (No. 4) to fasten the Handle (No. 31) to the Post (No. 29).
7. Use two Bolts (No. 22), washers (No. 24), spring washers (No. 25) and Nuts (No. 26) to connect the bottom of the Post (No. 29) to the Base Frame (No. 20).
8. Use two Bolts (No. 14), Washers (No. 9) spring washers (No. 10) and Nuts (No. 11) to connect the lower ends of the Supports (No. 21) to the inside of the base (No. 20). Then use Bolt (No. 14), Washer (No. 9) spring washers (No. 10) and Nut (No. 11) to connect the top ends of the Support to the post (No. 29). Check to make sure the nuts were tightened, and tighten the nuts in step 6.
9. Use Bolt (No. 32), Washer (No. 33) and Nut (No. 34) to attach the Boom (No. 35) to the top of the Post (No. 29), tighten Nut (No. 34) so that the boom (No. 35) can rotate freely, do not over tighten boom needs to be able to rotate freely.
10. Use Bolt (No. 23), Washer (No. 24) and Nut (No. 26) to fasten the lower end of the Long Ram (No. 28) to the Post (No. 29). Then use Bolt (No. 36), Washer (No. 24) and Nut (No. 26) to fasten the top of the Long Ram to the Boom (No. 35).
11. Slide the Boom Extension (No. 37) into the Boom (No. 35) and use Bolt (No. 14), Washer (No. 9) and Nut (No. 11) to secure at the desired load rating. Use Bolt (No. 38), Washer (No. 9) and Nut (No. 39) to attach the Hook and Chain (No. 40) to the end of the Boom Extension. (The boom has four different load ratings; select desired rating before use.)

How to Use

IMPORTANT: Stop pumping when the piston has been run out to the red stop mark, otherwise the product might not work properly.

• Check before each lift that all the screw unions are properly tightened.
• Never exceed the maximum permitted load according to the markings on the arm. The permitted load is given on a safety sticker on the arm as follows: 250 kg, 500 kg, 750 kg and 1,000 kg.
• Never use the product on an uneven surface or where there are ridges or expansion joints in the floor – this can cause the swivel wheels to turn, which can result in a risk of serious personal injury. For this reason the swivel wheels are not covered by the warranty. When moving with a load the load should hang as low as possible. Make sure that the load does not swing. Always lower the load carefully. Do not let it drop.
• Check the hydraulic cylinder and piston at regular intervals for leakage and/or corrosion. Keep them clean and well lubricated.
• Small amounts of hydraulic fluid can be forced out at the base of the piston or at the top seal. This is perfectly normal.
• When the product is not in use it should be stored with the arm and hydraulic cylinder in the lowest position, the support feet folded and the lock pins correctly inserted to minimise storage space.
• Only use hydraulic fluid of the type recommended by the manufacturer (grade ISO68) when refilling or changing the hydraulic fluid. Never mix different fluids and never use brake fluid, transmission fluid, or engine oil.
• Be careful when refilling hydraulic fluid, so that no impurities or foreign objects come in the hydraulic system – risk of material damage.
• Only use fresh, pure hydraulic fluid.
• Never allow any part of your body to come under a load when it is lifted up.
• Follow these instructions for best functionality and life span. Do not use the product for any other purpose than the one it is intended to be used for.

Maintenance

Bleeding the Hydraulic System and Refilling Hydraulic Fluid

Components:

1. Lowering valve
2. Piston
3. Refill cap for hydraulic fluid
4. Mount for pump handle

Procedure:

1. Open the lowering valve (1) by turning the handle anticlockwise.
2. Press down the piston (2) to its bottom position.
3. Remove the filler cap (3).
4. Check that the level of hydraulic fluid is just below the edge of the refill hole. Top up the hydraulic fluid, if necessary. Only use hydraulic fluid of the recommended type (see technical data).
5. Put the handle in the mount and pump up and down 10 full strokes.
6. Check the level of the hydraulic fluid again, and top up if necessary. Only use hydraulic fluid of the recommended type (see technical data).
7. Repeat steps 5 and 6 until the level of hydraulic fluid is just below the edge of the refill hole. Replace the filler cap.
8. Close the lowering valve by turning the handle clockwise all the way.
9. Lift and lower the arm slowly several times without load.
10. Do not use the product if the arm does not lift and lower smoothly. Have the product inspected by a qualified technician.
