Heavy-Duty Mechanical Steel Jacks (3 Tonne to 20 Tonne)
Engineered for rugged, reliable lifting, pushing, supporting, and lower-level positioning without hydraulic fluid or electrical power, these heavy-duty mechanical steel jacks (rack and pinion jacks) are built for harsh industrial environments. Designed to handle loads from 3 tonnes up to 20 tonnes, they allow dual-position lifting via either the top head or the low-clearance bottom toe.
Key Features:
 * Dual-Position Lifting (Head & Toe): Unique design allows full rated capacity on top of the head as well as on the bottom toe, ideal for low-clearance equipment where standard jacks cannot slide underneath.
 * Self-Locking Ratchet Crank Handle: Features a double-ratchet pawl system and folding safety handle that prevents kickback and holds the load securely at any height during operation.
 * All-Mechanical Rack & Pinion Drive: Precision-machined heat-treated steel gears deliver smooth, positive mechanical advantage with zero risk of hydraulic fluid leaks or pressure drops.
 * High-Tensile Steel Body: Heavy-gauge fabricated steel housing protects internal gearing and gear tracks from dust, debris, and severe site impacts.
 * Stable Wide Base Plate: Oversized, reinforced base footprint distributes heavy point loads evenly across flat ground and factory floors to prevent tipping.
Applications:
 * Lifting low-clearance heavy machinery, transformers, and industrial equipment
 * Railroad track maintenance, alignment, and timber sleeper replacement
 * Civil engineering, bridge support, and structural steel positioning
 * Shipyards, mining operations, and remote construction sites lacking power
