Depending on your building’s structure and your staff’s capabilities to assemble and wire a crane kit at your site
We also provide assistance in beam sizing, layout, and manufacturing. Our goal to produce a product you can be proud of, at the best possible price. continues to make Material Handling the leader in crane kit manufacturing.
Crane Kit Parts
- End trucks
– Top running/under running single girder/double girder
– Machine and hardened 6 inch end truck wheels for long life, not cast
– Dual drive motors, one per end truck, with bridge speed, depends on application needed
– 2 1/2 HP bridge motors.
– Bridge brakes as required by OSHA
– Bumpers and rail sweeps
- Crane Control Box
– Lockable-disconnect as required by OSHA
– Mainline disconnect operated from the pendant. This provides an extra level of safety by allowing the operator to immediately disconnect power if a relay sticks, or if other issues arise.
– Only one fused transformer for all controls. Many manufacturers use a separate transformer for the hoist and bridge; this can cause electrical feedback problems, which lengthens and complicates troubleshooting.
– End truck relays
– Mounting frame to mount control box to crane
- Festoon System to provide power along runways
– Festoon system
– Clamps, clips, brackets, and assembly.
- Pendant control station
– Single or double speed controls and momentary or maintain on/off mainline switch
– Pendant wire
– Strain relief cable
– Grommets, connectors, and hardware
- Festoon system for bridge power and control
– All hardware and brackets to mount to bridge crane
– C track type system with trolleys.
– Flat festoon cable for both control and power wire to hoist
- ASCE rail for runway
– With hook bolts and splice plates. Adjustable hook bolts allow for future alignment.
– ASCE 25#
- Conduit and wiring to bring power and break controls to end truck motors
– All connectors, flex tubing, and conduit to run from control box to end truck motors
– 16 AWG color coded and labeled conductors
We can pre-wire the system including:
- Wiring the pendant
- Terminating the festoon wires into the bridge control box
- Terminating the festoon wires into the hoist
- Wiring a power wire to connect to the collector show assembly
- Terminating end truck wiring in control box (you would still need to connect the other end to the motors.)
On Sight Assistance
- We provide on-sight assistance as needed: everything from a single senior fabricator, who will assure your staff assembles and/or installs the kit properly, to a full crew that can do the work for you.
- OptionsWe recommend the following options as we have found them to be useful:
- Strobe light activated on motion to warn others of crane and hoist movement.
- Separate pendant festoon allows the operator to stand next to or away from large or long loads. Pendant control stations run on separate tracks, instead of hanging from the hoist, and can be moved immediately across the entire span.
- Pendant operated horn to warn others of danger. OSHA states that systems “should” have a horn. While “should” is not mandatory, we strongly recommend for its added safety benefits.
- Dual power collectors. As a system ages, corrosion may occur in less used sections. The extra collector virtually eliminates potential phase lose, which causes equipment malfunction.
- Remote control with extra transmitter
- Increased wheels on end trucks to 12 inch diameter. Larger wheels and motors reduce wear and stress greatly thus increasing the life of the system.
- Multistep, infinitely-variable speed on bridge control. With variable speed control, the speed ramps up and down at a programmed rate, reducing load swing. Variable drives also allow very slow speeds when positioning loads, medium when traveling with large loads, or fast for no loads. The bridge speeds can also be increased to 150 FPM (a variable drive system allows speeds to be set to your specific needs).
- Variable drive on trolley and hoist motion
- Electrical Regeneration Unit. This unit uses energy to literally “feed” power back into the supply line. Typical electrical savings are 40%. Brake life is also increased.
