The H-Lift Mechanical Ratchet Jack MRTJ type is a heavy-duty lifting tool designed for field operations where hydraulic systems may be impractical. Utilizing a robust rack-and-pinion mechanism operated by a steel lever handle, it provides reliable mechanical lifting from both the head and the low-profile toe. This durable jack is essential for railway maintenance, structural moving, and heavy machinery installation, offering precise control and high stability on rugged terrain.

Available Capacities: 5 ton, 10 ton, and 15 ton
Mechanical rack-and-pinion design for reliable, oil-free operation
Dual lifting points: Head (full capacity) and Toe (rated capacity)
Low toe height allows access under minimal clearance loads
Durable steel construction with folding handle for compact storage

Technical Data
Safe Use of Jacks

The MRTJ Series Mechanical Ratchet Jack is a robust lifting tool designed for railway maintenance, mining, and heavy machinery positioning. Constructed from drop-forged alloy steel, it features dual lifting points (Top and Toe) to provide versatility in low-clearance environments.

↕️ Dual Lifting Points

Top Cap: Supports full rated capacity (5T, 10T, 15T).

Toe: Supports 50% of rated capacity (2.5T, 5T, 7.5T). Ideal for low-clearance lifting starting from the ground.

📐 Close Quarter Use

Designed with Double Lever Sockets, allowing the operator to insert the handle at different angles. Critical for effective jacking in tight or confined spaces.

🛠️ Rugged Construction

Features Drop Forged Alloy Steel components for superior strength in mining and shipyard environments. Plated Springs resist rust and corrosion.

🛡️ Safety & Stability

Built with a Large Base for a firm foundation. Equipped with Multiple Tooth Pawls for secure load holding and mechanical safety.

Q: Is the capacity the same on the toe and the top? A: No. For the MRTJ series, the Toe Capacity is exactly 50% of the Top Capacity. (e.g., MRTJ-10 lifts 10T on top, but 5T on the toe).

Q: What is a "double lever socket"? A: It allows the jack handle to be inserted in two different positions. This flexibility is critical when working in tight spaces where a full handle stroke might be obstructed in one position.

Selecting the Correct Jack

Jacks may be hydraulic or mechanical in operation and are available in a wide range of capacities and designs. Proper selection is critical for safety.

Key Considerations:

Type: Hydraulic, ratchet, screw, or journal jack.
Dimensions: Capacity, closed height, lifting height, and overall dimensions.
Accessories: Toe/claw attachments, screwed ram with locking collar, calibrated gauges for load measurement.
Support: Packing materials needed during jacking and to support the load once raised.

Safety Guidelines

Always

Store and handle jacks correctly.
Inspect jacks before use and before placing into storage.
Ensure the surface is level, even, and capable of taking the imposed load.
Ensure the jack is positioned so the load is applied in the correct plane.
Use packing capable of withstanding loads without crushing.
Lift and lower in small stages using support packing to minimize load falls.

Never

Never obliquely load (side load) jacks.
Never raise the load higher than necessary.
Never over-extend the jack beyond its rated stroke.
Never leave a load supported solely on jacks (use stands/packing).
Never reach under a load supported by jacks.
Never work or climb on a load supported by jacks.

Operation & Maintenance

Using Jacks Safely

Multiple Jacks: Most operations require multiple jacks. It is impossible to raise/lower them in perfect unison, causing uneven loading. Ensure jack capacity is adequate to handle load transfer. Keep the load level.

Floor Stability: Ensure the floor can withstand the point load. Use floor plates to spread the load if necessary. Avoid buried cables or pipes.

Contact: The jack head must be in full, firm contact with the jacking point. Use packers to prevent slipping.

Storage & Handling

Store jacks upright with the ram/rack/screw fully lowered to protect them from damage. Remove handles/levers and store separately. Never store damaged jacks.

In-service Inspection

Clean jacks regularly to remove dirt from racks, screws, and seals. Check hydraulic oil levels. Lubricate moving mechanical parts.

Defects to Watch For:

Failure to lift or lower; load slipping/creeping.
Cracked or distorted body/base.
Bent operating levers.
Hydraulic: Oil leaks, scored/distorted rams, inoperative release valves.
Mechanical: Chipped/worn rack teeth or screws, seized swivel heads.

⚠️ WARNING: Excessive grease on ratchet jacks can cause the holding pawl to stick, potentially dropping the load.
