• Plain Models: These are free-floating and do not have gears or chains. They are simpler and more cost-effective, suitable for general-purpose moving of products[1][2].

Key Features

Construction

• I-beam trolleys are typically made from strong steel or cast iron, ensuring durability and heavy-duty performance[1][2].

Adjustment and Fit

• These trolleys can be adjusted to fit various I-beam flange sizes. For example, they can fit I-beam flanges ranging from 2″ to 8″ or more, depending on the model[1][2][4].
• It is crucial to measure the I-beam correctly, focusing on the height of the beam rather than the width across the flange[2].

Headroom

• The headroom, or the distance from the under beam to the base of the trolley eye, varies between models. It can range from 2-1/2″ to 8-5/8″[1].

Capacity

• I-beam trolleys come in various weight capacities, ranging from 500 pounds to 10,000 pounds or more. The capacity depends on the specific model and application[1][2][4].

Operation

• Motorized Systems: For applications requiring motorized movement, different trolley models and chain systems are available but are not typically part of standard hand-push trolleys[2].

Wheels and Bearings

• High-quality I-beam trolleys often feature sealed bearings and self-aligning frames, ensuring smooth and efficient movement along the beam[1][4].

Applications

Industrial Use

• I-beam trolleys are commonly used in heavy-duty industrial applications such as paint finishing lines, automotive assembly plants, and other manufacturing processes[2].

Workshop Use

• They are also suitable for home workshops and smaller-scale operations where efficient and simple product movement is required[2].

Safety Considerations

Load Movement

• Ensure that the load is securely attached to the trolley to prevent accidents. Using hooks or other attachment methods is recommended[2].

Inclines and Curves

• I-beam trolleys are suitable for moving products around curves but should not be used for moving products up or down inclines, as this can cause dangerous conditions[2].

Maintenance

• Regular maintenance of the trolley, including checking the bearings and ensuring proper adjustment, is essential for safe and efficient operation[1].

Installation and Setup

Quick Installation

• I-beam trolleys are designed for quick installation on virtually any S-type I-beam. They often come with a manual screw mechanism for adjusting the width to fit the beam[1].

Additional Components

• Some models include additional components such as lifting eyes for attaching hoists and locking rings to prevent width changes[1].

Pricing and Availability

Cost

• The cost of I-beam trolleys varies widely depending on the model, capacity, and features. Prices can range from a few hundred dollars to over a thousand dollars[1][2][4].

Availability

Guide to I-Beam Trolleys

What is an I-Beam Trolley?

An I-beam trolley, also known as a girder trolley or monorail trolley, is a device designed to run along an I-beam or a similarly shaped track. It is used to lift and move heavy loads such as machinery, construction materials, or industrial equipment.

• Features: Often include advanced control options such as variable speed, remote control, and automated operation[4].

Geared Beam Trolleys

• Operation: Use a geared mechanism to provide more precise control and positioning of the load.
• Applications: Commonly used in applications requiring high accuracy, such as manufacturing or assembly lines.
• Features: Provide precise movement and are ideal for tasks that require careful load placement[4].

Motorized Beam Trolleys

• Operation: Powered by an external power source, such as compressed air or hydraulics.
• Applications: Offer even greater lifting capacity and can be used in hazardous environments.
• Features: Suitable for heavy-duty applications and environments where electrical power may not be safe to use[4].

Frequently Asked Questions (FAQs)

Here are five frequently asked questions about trolleys for cranes in China, along with detailed answers:

What are the key components of a crane trolley?

A crane trolley is a crucial component of a crane system, responsible for moving the load along the crane’s beam or girder. The key components include the trolley frame, which provides the structural support; the hoist mechanism, which could be a wire rope hoist or a chain hoist, responsible for lifting and lowering the load; the traveling mechanism, which includes motors and gears that enable the trolley to move along the crane’s tracks; and the control system, which can be manual, remote, or cabin-controlled, allowing the operator to manage the trolley’s movements.

How do you determine the lifting capacity of a crane trolley?

Determining the lifting capacity of a crane trolley involves several factors. The rated lifting capacity is the maximum weight that the trolley can lift in a single operation under normal working conditions. This does not include the weight of the hook and any moving pulley groups, but it does include the weight of any removable material handling devices such as grabs or electromagnetic suction cups. The capacity is typically marked on the trolley’s nameplate and is measured in tons or kilograms.

What are the different types of trolley traveling speeds?

The traveling speed of a crane trolley refers to the speed at which the trolley moves along the crane’s tracks with the rated load. Trolleys can have multiple traveling speeds to accommodate different operational needs. For example, a trolley might have a fast speed for moving without a load and a slower speed for precise positioning with a load. These speeds are usually specified in meters per minute (m/min) and are indicated on the trolley’s nameplate.

How is the working class of a crane trolley determined?

The working class of a crane trolley is determined by two main factors: the frequency of use (utilization class) and the size of the load it bears (load state). The working class ranges from M1 to M8, with M1 being the lightest and M8 being the heaviest. This classification helps in ensuring that the trolley is suitable for the specific working conditions and can handle the required workload efficiently and safely.

What kind of maintenance and inspection are required for a crane trolley?

Regular maintenance and inspection are critical for ensuring the safe and efficient operation of a crane trolley. This includes routine checks on the trolley’s mechanical components, such as the hoist and traveling mechanisms, as well as the control systems. The trolley’s tracks and rails should also be inspected for any wear or damage. Additionally, load testing and quality assurance checks should be conducted periodically to ensure compliance with safety standards and to prevent any potential failures. Comprehensive documentation of these tests and inspections is essential for maintaining transparency and ensuring the trolley’s reliability.
