CMI - 4" Pulley with Stainless Steel Bushing

The CMI 4" Pulley is designed with durability and performance in mind, featuring stainless steel sideplates and a 4" aluminum sheave. It incorporates a stainless steel bushing and axle, ensuring reliable operation in demanding environments. The pulley is robust with a Minimum Breaking Strength (MBS) of 20,000 lb, making it suitable for handling substantial loads. Additionally, it accommodates ropes up to 5/8", offering versatility for various applications.

This pulley is ideal for scenarios requiring a strong and dependable component, such as rescue operations, rigging, and heavy lifting tasks. Its robust construction and high load capacity make it well-suited for use in both urban and rural environments where reliability is crucial. However, users should be aware that while it exceeds certain test standards, it is not certified, which may limit its use in some professional settings.

With a Minimum Breaking Strength (MBS) of 20,000 lb, the CMI 4" Pulley is capable of handling substantial loads. This makes it suitable for heavy-duty tasks such as lifting and pulling in various settings. The stainless steel components provide added durability under stress, ensuring the pulley remains operational even under challenging conditions.

While the CMI 4" Pulley is robust and versatile, it is not certified despite exceeding NFPA 1983-2006 tests. This may limit its use in certain professional or regulated environments where certification is required. Additionally, its weight of 2.2 lb might be a consideration for those needing lightweight gear for extended carry. Users should evaluate these factors based on their specific needs and scenarios.

The CMI 4" Pulley accommodates ropes with a diameter of up to 5/8". This makes it versatile for a range of applications, allowing users to employ various rope sizes depending on the task at hand. It's important to ensure that the rope used is appropriate for the load and conditions to maximize safety and efficiency.

The CMI 4" Pulley is constructed with stainless steel sideplates and a stainless steel axle, which contribute significantly to its durability. These materials are known for their resistance to corrosion and wear, making the pulley suitable for use in harsh environments. The aluminum sheave also adds to its strength while keeping the overall weight manageable.

The CMI 4" Pulley exceeds NFPA 1983-2006 tests, but it is not certified, which may be due to the manufacturer's decision or specific certification requirements. Certification often requires additional testing and compliance with regulatory standards, which can be costly and time-consuming. While the pulley is built to high standards, users should consider this factor when selecting equipment for regulated environments.

The CMI 4" Pulley measures 8x4.75 inches and weighs approximately 2.2 lb, balancing strength and manageability. Its size and weight make it suitable for use in various settings, providing a robust solution without being overly cumbersome. However, for those requiring ultra-lightweight gear, the weight might be a consideration in long-duration or mobile operations.

The CMI 4" Pulley uses stainless steel for its sideplates and axle, and aluminum for its sheave. Stainless steel is chosen for its strength and resistance to corrosion, making it ideal for demanding environments. Aluminum is used for the sheave to reduce weight while maintaining durability. These materials ensure the pulley can withstand heavy use and harsh conditions.

The CMI 4" Pulley is robust and capable of handling significant loads, making it suitable for many rescue operations. However, its lack of certification may limit its use in professional settings where certified equipment is mandatory. Users should assess the requirements of their specific application and consider whether certification is necessary for their operations.
