M.R. Manila Rope Pulleys in single, double, and triple-sleeve — for block-and-tackle rigging and manual lifting across construction sites and rural worksites in NE India.
An M.R. (Manila Rope) Pulley is a cast iron or steel-framed snatch block with one, two, or three rope sheaves (grooved wheels) mounted on a common axle. The sheave groove is profiled to accept fibre rope — manila, sisal, or polypropylene — and to guide it smoothly under load without kinking or crushing the fibres. M.R. pulleys are used in block-and-tackle rigging systems where a series of fixed and moving pulleys with a continuous rope creates a mechanical advantage that allows a small applied force at the hauling end to lift or move a much heavier load.
Multi Trade Combines stocks M.R. pulleys in single, double, and triple-sleeve configurations at our Guwahati Lifting & Handling counter. These are fundamental rigging tools for construction, rural site work, and material handling operations across Northeast India where powered lifting equipment is impractical — remote hill sites in Arunachal Pradesh, Manipur, and Nagaland, island river communities in Assam, and small building projects where a gin pole and block-and-tackle rig is more practical than a mobile crane.
Rural building contractors constructing homes, community buildings, and small commercial structures across Assam, Meghalaya, and Mizoram use M.R. pulleys in gin-pole configurations to raise roof trusses, ridge beams, and precast elements without powered plant. A two-man team with a single-mast gin pole and a four-sheave block-and-tackle can raise timber roof frames and masonry elements weighing several hundred kilograms with manual pull — work that saves the cost of a crane hire for simple lift operations.
Tea estate factory workers across Upper and Lower Assam use pulleys for internal material lifting — moving bale presses, heavy equipment components, and bags of withered leaf using hand-rigged tackle systems. Inland waterway cargo handlers at riverine ghats on the Brahmaputra and its tributaries use manila rope and block-and-tackle for loading and positioning cargo on country boats and inland barges.
Forestry and timber operations in Assam's reserve forest fringes use M.R. pulleys in log-rigging operations to winch felled timber to extraction roads. The pulley is also a standard rigging component for the monkey cranes and builder hoists available from our Light Construction Machinery range — the two products are often used together on building sites for material vertical lifting.

A Manila Rope (M.R.) pulley is a snatch block or sheave block designed to guide and redirect a fibre rope — manila, sisal, or polypropylene — in a lifting or hauling rig. On construction sites and rural worksites without power, M.R. pulleys are used in gin-pole, derrick, and block-and-tackle arrangements to multiply the mechanical advantage of manual pull so that two or three workers can lift loads that would otherwise require a machine. A single moving pulley doubles the mechanical advantage; two moving pulleys with a fixed head block give four-to-one mechanical advantage. The single, double, and triple-sleeve M.R. pulley range at Multi Trade Combines allows building any block-and-tackle configuration up to practical limits.
A single-sleeve M.R. pulley (one sheave) is the basic unit — it redirects one rope run and provides no mechanical advantage when used as a fixed point, but doubles the pull when used as a running (moving) pulley in a tackle. A double-sleeve pulley has two sheaves side-by-side on a common axle in a single frame, allowing two rope runs to pass through simultaneously — used in compound block-and-tackle rigs where a single block would create unacceptable rope angles. A triple-sleeve pulley with three sheaves further extends the rope capacity of a tackle rig and is used in heavy dead-lift applications where a large mechanical advantage is required without adding more tackle stages. The load rating per sheave is the same; the additional sheaves simply accommodate more rope runs.
