Maintenance program

Why our preventative maintenance program may be right for you:

• We push beyond industry standards to be the best.
• Our preventative maintenance plans are here to save you money. By caring for your crane or hoist along the way it cuts down on costly delays and repairs. Our team of technicians will work with you to design a program and schedule that meets your unique needs. This approach helps to eliminate system failures, extend equipment life, and improve performance. We do this by regularly inspecting the hoist, rope, hook, controls, and structure, making sure the equipment is certified, and we will help you modernize or upgrade your equipment as requested.
• Part of our preventative maintenance program includes regularly scheduled visits to examine, test, and perform routine maintenance on your cranes. With these visits, we will provide a written report containing the crane or hoists conditions, any recommended actions, and a prioritized list of any system or equipment malfunctions that were found.
• Our team is dedicated to providing you with the best service and we promise that we will always meet, if not exceed, the manufacturer’s recommendations.

Why are daily inspections important?

Daily inspections are important for the continued maintenance and safety of the crane, its operator, and those working around it.

Only trained and accredited personnel can perform maintenance and repairs on overhead crane systems. However, the crane and hoist should be inspected at the beginning and the end of every shift; this should be done from the floor, a catwalk, or another safe point. If any part of the crane is malfunctioning, making odd noises, or making irregular movements, stop using it immediately; then give us a call and we will come out to get you back up and running quickly and safely.

Crane Inspection Checklist

• All required safety equipment is present and being used
• Crane inspector is trained and authorized to use the equipment
• The operator knows the location of crane disconnect switch
• Confirmation that no warning signs are on or around the pushbutton pendant
• No workers are performing other duties nearby
• No obstructions in or around the area
• The area is large enough to move and place materials safely
• Ensure all below-the-hook devices are for that crane
• Check that it can safely lift loads
• Confirm that load capacity is less than or equal to the capacity of the crane

Once the area is clear, an initial safe equipment check needs to be done before any crane controls are touched. This includes checking:

• No loose, broken, or damaged parts on hoist, trolley, bridge, runway, or electric systems
• The wire rope is reeved and seated in drum grooves properly
• Bottom block isn’t twisted (no two lengths of wire rope touching)
• Nothing is touching or close to power sources
• Enclosures are secured
• No wires have been pulled from strain reliefs or bushings
• Pushbutton pendant controls aren’t damaged (i.e. cracks, torn parts, or missing labels)

From here the operator needs to inspect the overhead crane for any malfunctions or safety hazards.

Daily Equipment Safety Inspection (Powered Systems):

• Turn off pushbutton
• Check that buttons are not sticking and operating smoothly
• Released button should always return to off position automatically
• When the pushbutton is turned on, the crane warning device should operate properly
• When the button is pushed to the up position, the hoist hook should rise
• Upper limit switch checked to make sure it is working properly
• Check all other pushbutton controls to ensure they work properly and move in the correct direction

Daily Equipment Safety Inspection (Hooks):

• No more than 10% wear is showing on any part of the hook
• Check for bending, twisting, and cracks
• Safety latches are in place and functioning properly
• Hook nut, if visible, is tight and locked to the hook
• Hook can rotate freely without grinding

Daily Equipment Safety Inspection (Bottom Block Assembly):

• Check for structural damage or cracks
• Capacity markings are present
• Sheaves are smooth and can rotate freely without any grinding
• Sheave guards are intact and unbroken

Daily Equipment Safety Inspection (Wire Root and Load Chain):

Examine wire rope and load chain by walking 360 degrees around hook block and making sure there are no signs of:

• Diameter reduction
• Broken wires
• Kinking, cutting, crushing, un-stranding, or thermal damage of wire rope
• Cracks, gouges, nicks, corrosion, or distortion on any chain link
• Wear at contact points
• Rough operation of chain sprockets

Daily Equipment Safety Inspection (Miscellaneous Items):

• Bridge and trolley motor brakes are operating properly
• Little or no hook drift when controls are released in up or down positions
• Bridge and trolley are on-track
• Bridge and trolley are functioning smoothly
• No loose items are on the crane that could fall
• No oil is leaking
• Working fire extinguishers are available
• Air and hydraulic lines are in working condition
• All below-the-hook devices in good condition
