Hobbies And Interests
Carriers
Carriers can be single-, two-, three- or four-trolley configurations. Single trolley systems come with a posterior cam tail and an anterior contact bumper attached straight to a load-attachment bracket. They are designed for maximum loads of 750 pounds. Two-trolley systems have either an overhead load bar or an inverted platform designed for even weight distribution between front and rear trolleys and have load capacities to a maximum of 1,500 pounds. These are the most common trolley systems used.
Three-trolley systems have a two-trolley basic set-up and load capacity, with a front extension for longer loads. Four-trolley carriers are two-trolley configurations fitted with a couple of small load bars attached to a longer weight-bearing load bar. The position of the trolley sets facilitates direction reversal for extended product assembly, as in vehicle frame side applications. Maximum load capacity is 3,000 pounds.
Chain
Heavy duty universal link chains are constructed with symmetrical drop-forged chain pins having single-bolt pitches that can be easily assembled and taken apart using standard hand tools. The universal link chain configuration allows for shorter vertical and horizontal curve distances requiring no roller turn or traction wheel placements.
Providing direction flexibility, the chain's heat-treated side links are hardy enough to last through multiple, long-term use. Ball bearings and wheel races are forged from concentrated carbon and chromium steel alloys, enabling the strong chains to withstand wearing and corrosion.
Drives
Unibilt drive units are enclosed-track systems with a single compact design, driven by a motor/reducer combination that works to directly power the system with efficiency. The combination also configures the entire Unibilt conveyor system to operate with low noise production and less maintenance requirements. The drive system thus ensures accurate overload control and longer operating life for the conveyor.
Track
Unibilt conveyors are formed as enclosed track systems that facilitate uncontaminated operations, with chains and mobile components shielded from environmental elements. The track system is fashioned from patented steel alloy material, usually carbon, for durability and strength. This feature is what sets Unibilt conveyors apart from others.
