One-Sided Only Lifting, Mounting, & Bolting

Makuri have progressively developed a true one-sided bolting and installation design called the MAK-Lok system

There is much to be gained by changing to and using faster and safer one-sided mounting systems for all types of chute liners.

The Makuri MAK-Lok system is comprised of 4 major components;

The nut/bolt
The mounting plate
The bolt head receiver – welded into the mounting plate
The lifting & alignment Tool

The bolt does not require contact with the slotted hole in the chute wall for proper location, so no loss of functionality is encountered if the slots are not perfectly cut.
The locking element prevents the head of the bolt turning in the hole after installation, dramatically reducing the chance of bolts disengaging
Bolts on standard T and S style assemblies are pre-fitted with dry threadlocker at the factory. The threadlocker activates when the bolts are tightened, preventing loosening of the nuts during operation
The wider bolt heads provided on MAK-Lok bolts allows for greater overhang on either side of the slot, further reducing the chance of dislodgement if chute wall slots are in poor condition
Installation nuts are fitted with through-holes to facilitate removal. The bottom end of the nuts are fitted with nylon inserts to prevent ingress of dirt into the bolt hole.
Nuts are extended into the backing plate of the wear plate. This ensures that the nut is still able to clamp effectively even with all wear material removed.
Installation sockets are through hardened and are fitted with replaceable dowels, allowing for replacement on site if breakages occur
Our rail system allows chutes to be converted to the MAK-Lok system without the need to physically modify the chute.

Two-sided Lifting, Mounting & Bolting

Makuri have progressively developed a range of advanced two-sided bolting and installation systems.

Plug Weld

Two-Sided Bolting

MAK- BB System (Back Bolted)

Allows for the full life of the liner to be obtained
Allows for flat packing
Fast, safe and versatile mounting and lifting options
Can be used with Makuri’s 5-step installation system

MAK-CB Bolts (Capped Bolts)

Unique Makuri bimetallic bolts with MAK-Hard white iron caps
Prevents wear to the structural part of the bolt
Prevents streaming wear in the bolting hole
Allows for flat packing

MAK-FT Bolts (Fishtail Bolts)

Makuri liners can be manufactured to suit any bolt profile
Fishtail bolts are readily available and do not turn inside the hole
Allows for some degree of misalignment
Liners can be flat packed

MAK-HT Studs (High Tensile)

Provides for simple installation, but requires additional space for packing
Weld-free design ensures tensile strength of studs is maintained
Allows for studs to be fully tensioned in critical applications

MAK-CS Bolts (Countersunk)

Liners can be manufactured to suit any standard CS bolts available on site
In some applications, use of these can allow the full thickness of wear material to be utilised without damaging the bolt head
Liners can be flat packed

MAK PW Slots (Plug Weld)

Can be used where installation conditions do not allow for use of bolts, or where chute conditions are not acceptable for bolting

All bolting options can be supplied with Nyloc nuts, standard hardened washers, self-aligning sealing washers and self-locking washers.

Typical Problems

Poor bolting and retention systems, like countersunk bolts, are still being offered by designers and suppliers based on price
Most current systems still require personnel on both sides of the chute to fit both liners and bolts correctly
After bolt heads wear off liners fall out and damage belts and downstream processes
Damaged bolts are difficult to remove from the chute & require cutting
Liners need to be removed early to avoid bolt failure
Lack of choice in what retention system is best for each liner application
Having personnel only on the one side for mounting and securing adds a significant safety advantages having less personnel doing the job as well as not having personnel in potential confined areas

Makuri Solutions

Makuri can supply a wide range of mounting options to suit existing site fitment practices and can custom-design additional systems to suit individual requirements.

We have developed many proprietary and patented designs that address the demands of the industry for safer and faster relines in most applications and working to cover all such liners applications and conditions as a priority.

Applying the correct liner mounting system allows us to guarantee a lower TCO and provide greater sustainability to our industry
