4.5 Ton Mini Excavator

4.5 Ton Mini Excavator Product Functions

Within its operating envelope, the HT45 compact excavator executes a complete excavation work cycle. The boom-arm combination opens trenches to a maximum depth of 2545mm and lifts material to a digging height of 4450mm, while the 3050mm dumping height clears the side walls of standard dump trucks and trailers. The integrated dozer blade—with 359mm of lifting travel and 268mm of digging depth—performs backfilling, surface grading, and light earthmoving without requiring a separate attachment. Thanks to the 1170mm minimum tail swing radius, the superstructure can rotate a full 360° inside narrow trenches and against structures, minimizing repositioning and extending productive time. The 35° climbing ability and 34.8kPa ground pressure keep the unit operational on inclined sites and load-bearing-sensitive surfaces.

Mini Excavator 4.5 Ton Features

The HT45 small excavator combines a set of practical engineering characteristics drawn directly from its specification. Its compact dimensions—4400mm overall length with the arm lowered, 2200mm overall height, and 1530/1600mm overall width—permit road transport on standard trailers and access into low-clearance or gated sites. The 22MPa hydraulic system, fed by a 32cc plunger main pump with 99L/min flow, delivers smooth and responsive power to both the working tools and the running gear. A two-speed plunger travel motor switches between a 2.4km/h working crawl and a 4.6km/h fast transit mode, improving cycle efficiency on multi-point job sites. The 60L fuel reservoir and 75L hydraulic tank support extended working shifts with fewer interruptions for refueling, and the 557mm platform ground clearance helps the machine cross obstacles and debris on rough terrain.

Mini Excavator 4.5 Ton Application Scenarios

The HT45 4.5 ton small excavator fits a broad range of working environments:

• Urban construction: foundation excavation for small buildings, basement digging in confined lots, underground pipe corridors.
• Utility engineering: trenching for water supply, gas, electricity, and telecom cable installation.
• Municipal works: road repair, sidewalk leveling, drainage ditch maintenance, curb installation.
• Agriculture and landscaping: pond excavation, orchard soil preparation, tree planting, garden and park landscaping.
• Rural construction: house foundations, farm building earthworks, small-scale land leveling.
• Interior and tunnel work: the 1170mm minimum tail swing radius enables operation in narrow corridors, basements, and tunnels.
• Rental fleets: compact transport size and low ground pressure make it an economical, versatile rental unit.

The machine is suitable for construction sites, narrow urban streets, soft-soil areas, slopes up to 35°, and restricted zones where full-size excavators cannot be deployed.

Hightop Group Service

Hightop maintains a structured after-sales support system for every HT45 small excavator. The warranty covers manufacturing defects in major assemblies for the contractually agreed period, and our service team responds to technical inquiries within 24 hours on working days. The after-sales flow follows clear steps: report the issue with photos or videos → our engineers provide remote diagnosis → where parts are required, we dispatch replacements or guide local repair → for major faults, on-site service or workshop repair is arranged. Technical support includes remote guidance during commissioning and operator training, plus access to a downloadable parts catalog and maintenance documentation. Spare-part supply is coordinated to keep your machine running with minimal interruption.

Common Problems With 4.5-ton Small Excavators

Q1: What is the delivery time for the HT45 4.5 ton small excavator? 

Standard production takes 15–30 days depending on configuration and order quantity. Sea freight to the destination port generally requires 20–40 days after loading. A confirmed delivery schedule is stated in the sales contract, and we update you on production and shipping progress throughout the process.

Q2: Do you support customization? 

Yes. Options include bucket capacity, quick coupler, extra auxiliary hydraulic lines for attachments, dozer blade configuration, machine color, and logo marking. Contact our sales team with your project requirements to receive a tailored quotation and production schedule.

Q3: What is the warranty period and coverage? 

The HT45 carries a standard warranty covering manufacturing defects in major assemblies. The warranty term and coverage scope are defined in the sales contract—typically covering the engine and hydraulic system for a specified period from the shipment date. Paid extended warranty options are also available.

Q4: How is the machine shipped and packaged? 

The excavator is secured in a 40ft container, or shipped by flat rack or RO-RO vessel depending on size and destination. We handle export packing, container loading, and all export documentation, and provide tracking information once the vessel departs.

Q5: Are spare parts readily available?

Yes. We stock frequently replaced consumables such as filters, seals, hydraulic hoses, and wear parts. They can be shipped together with the machine order or dispatched separately to your location on demand.

Q6: Do you provide operator training and technical documentation? 

We supply a complete documentation package—operation manual, parts catalog, and maintenance schedule—together with operation videos and remote technical guidance. On-site training can be arranged for fleet customers through our service network, either at the factory or at your project site.
