Maintenance has been performed on the lift trolley, re sealed the main drive gear box it was quite dry inside and in need of new seals and lubrication. Inspected the vertical gear box and resealed it, re tensioned the vertical drive chain after removing gear box and finding since last year the chain had become somewhat slack causing it to rub on the frame. Purchased a new LED light bar to replace the aging and failing flourescent light that was in place. greased all pillow block bearings and replaced old Zerk ( grease nipple) on some bearings to allow for easier lubrication. |
