Different Types of Crane Maintenance and Electric Hoist Maintenance Philippines
The Importance of Crane Maintenance
Crane maintenance is the process of inspecting, cleaning, lubricating, adjusting, and repairing the components of a crane. It includes checking the structural integrity, electrical systems, mechanical parts, hydraulic systems, and safety devices of the crane. Crane maintenance should be performed by qualified technicians who follow the manufacturer’s recommendations and industry standards.
The frequency of crane maintenance depends on several factors, such as the type of crane, the usage of the crane, the environmental conditions, and the regulatory requirements. Generally speaking, cranes should be inspected daily before each shift, weekly for minor issues, monthly for major issues, and annually for comprehensive evaluation. Cranes should also be inspected after any abnormal event, such as an overload, a collision, or a power outage.
Some of the benefits of crane maintenance are:
It reduces the risk of accidents and injuries caused by malfunctioning or worn-out parts.
It extends the lifespan and performance of the crane and its accessories.
It lowers the operating costs and downtime of the crane.
Some of the common crane maintenance tasks are:
Cleaning the crane from dust, dirt, grease, oil, and debris
Lubricating the moving parts of the crane with the appropriate grease or oil
Checking the alignment and tension of the wires, ropes, chains, and belts
Inspecting the hooks, slings, clamps, and other lifting accessories for wear and tear
Testing the brakes, clutches, limit switches, emergency stops, and other safety features
Measuring the voltage, current, resistance, and continuity of the electrical circuits
Adjusting the settings and calibrating the sensors and indicators of the crane
Replacing or repairing any damaged or worn-out parts of the crane
Overhead cranes consist of a bridge or a beam that spans over a work area and a trolley that moves along the beam with a hook or a lifting device attached to it. Overhead cranes are commonly used in factories, warehouses, workshops, and construction sites.
To maintain an overhead crane, you should follow these steps:
Inspect the crane daily before use. Check for any signs of wear, damage, or malfunction in the bridge, trolley, hook, wire rope, electrical components, brakes, limit switches, and safety devices. Report any issues to the supervisor or the maintenance team immediately.
Lubricate the moving parts regularly according to the manufacturer’s instructions. Use the appropriate type and amount of lubricant for each part. Avoid over-lubricating or under-lubricating the parts as this can cause excessive friction or corrosion.
Clean the crane periodically to remove any dust, dirt, grease, or debris that may accumulate on the surface or inside the components. Use a soft cloth or a brush to wipe off the dirt and a mild detergent or solvent to remove the grease. Do not use abrasive materials or harsh chemicals that may damage the paint or the metal.
Perform preventive maintenance according to the manufacturer’s recommendations or as required by the local regulations. Preventive maintenance involves checking, adjusting, repairing, or replacing the parts that are subject to wear and tear or deterioration over time. Preventive maintenance can help extend the life span of the crane and prevent costly breakdowns or accidents.
Schedule periodic inspections by a qualified technician or inspector who can assess the condition and performance of the crane and identify any potential problems or risks. Periodic inspections should be done at least once a year or more frequently depending on the usage and environment of the crane. Periodic inspections can help ensure compliance with the safety standards and regulations.
Gantry cranes are a type of crane that has a horizontal beam supported by two or more legs that run on rails or wheels. They are often used for lifting and moving materials in outdoor areas or large indoor spaces. Gantry crane maintenance is similar to crane maintenance but with some specific considerations.
Some of the common gantry crane maintenance tasks are:
Checking the condition and alignment of the rails or wheels that support the gantry crane
Inspecting the stability and levelness of the gantry crane structure
Cleaning and lubricating the bearings and rollers of the gantry crane
Testing the speed and smoothness of the gantry crane movement
Verifying the load capacity and balance of the gantry crane
Jib cranes are a type of crane that has a horizontal boom attached to a vertical mast that can rotate around a fixed point. They are often used for lifting and moving materials in confined spaces or within a limited radius. Jib crane maintenance is similar to crane maintenance but with some specific considerations.
Some of the common jib crane maintenance tasks are:
Checking the condition and alignment of the mast that supports the jib crane
Inspecting the rotation mechanism and bearing of the jib crane
Cleaning and lubricating the swivel joint and pinion gear of the jib crane
Testing the angle and range of motion of the jib crane
Verifying the load capacity and balance of the jib crane
Electric hoists are devices that use an electric motor to lift and lower loads with a wire rope or chain. They are often attached to cranes or other lifting equipment to enhance their functionality. Electric hoist maintenance is similar to crane maintenance but with some specific considerations.
Some of the common electric hoist maintenance tasks are:
Checking the condition and tension of the wire rope or chain that lifts the load
Inspecting the condition and alignment of the sheaves or sprockets that guide the wire rope or chain
Cleaning and lubricating the gears and bearings of the electric hoist motor
Testing the operation and performance of the electric hoist motor
Verifying the load capacity and speed of the electric hoist
