Product Overview

The front brace assembly for the ZOOMLION QUY80, QUY260 and ZCC crawler cranes is supplied as a lower and upper pair — two braces, new, for the front of the machine. Like most heavy equipment spare parts, it is ordered by number rather than by description, so the reference on the old brace and the model on the machine plate are what the order is built from.

The lower and the upper are not the same component: they carry different references and different geometry, and they are listed together here so a workshop can renew the pair in one job instead of waiting on two deliveries weeks apart. Each one arrives complete and ready to fit, rather than as a bare bracket that has to be built up from the old part.

Most crane spare part orders like this leave us after a knock at the front end, a seized roller, or a planned overhaul where the braces come off anyway and the old ones are not worth refitting. What hurts in those situations is not the price of the bracket — it is a crane standing idle while somebody works out which reference belongs on the machine.

Specifications

Build & Finish

• Painted steel bracket. The brace body is heavy steel with a glossy yellow paint finish carried over the whole face, including the edges, so a machine that lives outdoors is not starting from bare metal.
• Black rollers on pivoting arms. The rollers sit in the arms and should turn freely by hand; a roller that drags or rocks on its pin is the usual reason a brace comes off a machine in the first place — the first thing crane parts suppliers should check on a new one.
• Coiled spring. A coiled spring sits in the linkage and returns the arm. Work it through its travel before the brace goes on the crane, not after.
• Drilled mounting holes. The holes are drilled through the bracket flanges and are meant to line up with the machine's fixing points — always compare them with the old part before lifting the new one into position.
• Threaded studs. Studs stand proud of the bracket face, ready for nuts. Run a nut down each one on arrival; it takes a minute and catches any thread damaged in transit.
• New condition throughout. No straightening, no re-welding, no repainted used parts. Every crane spare part we send arrives as a new component, which is the only condition worth putting back on a lifting machine.

Model Coverage & Fitment

1. Match the model on the plate. This assembly is confirmed for the ZOOMLION QUY80, the QUY260 and the ZCC crawler range — the same crawler machines we cover for undercarriage parts. Quote the full ZCC designation rather than just "ZCC" — the series covers more than one machine.
2. Read the reference on the old brace. YLD7P/61-03020 and YLD7P/61-03010 cover the lower and the upper brace. They are separate parts and one will not substitute for the other.
3. Photograph the old part. Front, back and mounting face, with a tape or rule in one shot for scale. Numbers get painted over or ground off on machines that have worked for years, and clear photos usually settle it.
4. Measure if the number is gone. Hole spacing, stud length and pin diameter are enough for us to cross-check the reference against your machine.
5. List what else came off. Pins, nuts, washers and roller pins often leave with the brace; naming them up front stops the crane waiting on a second delivery.
6. Send it before you order. We compare your photos and figures against the ZOOMLION crane parts reference and confirm whether you need the lower, the upper or the pair before anything is packed.

Installation & First Run Checks

• Support the front end first. Block the structure before the fixings come out — standard practice on any construction machinery spare parts repair — and lay the washers and shims out in the order they came off so nothing has to be guessed on reassembly.
• Compare old and new on the bench. Hole pattern, stud length, arm angle and roller position should agree before anything is lifted into place; a mismatch is far easier to see on the ground, which is why crane parts suppliers check it before dispatch.
• Run the fixings on by hand. Finger-tight first, so the holes tell you straight away if the bracket is not sitting square against the mounting face.
• Torque to the manual. Use the figure the crane's maintenance manual gives for these fixings rather than a value borrowed from another model or a generic heavy equipment spare parts chart.
• Sweep the linkage through its full travel. The arms should pivot without binding and the spring should pull them back; a stiff roller shows up here rather than on the first lift.
• Re-check after the first shift. Nuts settle and paint compresses under washers, so a second torque check once the machine has worked is normal practice on a structural repair.

About ZOOMLION

ZOOMLION Heavy Industry Science & Technology Co., Ltd. was founded in 1992 and builds high-tech equipment for the engineering and agricultural industries. It has grown into a global enterprise with 10 major categories, 56 product lines and close to 600 products, and it was the first construction machinery company in China to list on both the Shenzhen and Hong Kong stock exchanges, with registered capital of RMB 7.664 billion. Its current direction is high-end equipment that brings engineering machinery, agricultural machinery and financial services together.

That scale is also why the model and the build year matter when you order a front brace assembly: a machine built in one year does not always carry the same front-end bracket as one that left the works a few years later. We have spent close to ten years as one of the crane parts suppliers working with ZOOMLION crawler cranes, and our customers now cover more than 20 countries, with after-sales service stations in a number of them. For new and revised ZOOMLION crane parts, our engineers can also attend on site when a repair needs more than a parts counter.

Ordering & Delivery

1. Send the reference. Tell us the number from the old brace, or the machine model with photos, and we confirm which brace you need. One piece is enough — there is no minimum beyond a single brace, whether you are ordering one assembly or a mixed pallet of construction machinery spare parts.
2. Choose the trade term. EXW, FOB, CFR and CIF are all available, with loading through Shanghai, Dalian and other ports to suit your route.
3. Settle payment. T/T and Western Union are both accepted, or as agreed when the order is confirmed.
4. We pack and dispatch. Each brace travels in a plywood box for export. Most parts are in stock, undercarriage parts included; delivery usually takes 7-20 days, according to the quantity.
5. Warranty cover. The assembly carries a warranty of 2500 working hours or one year.

Technical Support & Model Matching

Not sure which part fits your machine? Send the part number, the machine model, and a photo of the nameplate or the worn item, and our engineers — each with more than ten years in the construction machinery business — will confirm the correct reference and quote it. We advise on installation, help trace faults, and answer technical questions before and after dispatch. Since 2017 we have built this support on a supplier network covering FUWA, SANY, XCMG and ZOOMLION crane parts, so older and hard-to-find references can usually still be sourced.
