Product Details
Compact Crawler Spider Crane
4‑Ton Spider Crane for Lifting in Confined Spaces
The Onchtech 4‑ton spider crane is a compact crawler crane designed for indoor passages, rooftops, and work around obstacles. With an overall width of approximately 1 m, it can access areas where large cranes cannot reach. Equipped with rubber tracks, a telescopic boom, and extendable outriggers, it handles equipment installation, component lifting, and maintenance hoisting. It is suitable for contractors, equipment rental companies, project purchasers, and industrial users facing challenges such as limited access, scattered work positions, or restricted overhead space.This product is CE certified.
Core Performance & Structural Configuration
4‑Ton Rated Lifting Capacity
The crane has a rated capacity of 4 tons, covering common lifting needs for industrial equipment, building materials, and engineering components. The actual liftable weight depends on the working radius, boom length, outrigger status, and site conditions, and should be verified against the load chart for the specific configuration.
7‑Section Telescopic Boom for Height Reach
The 2.8 m × 7‑section high‑strength manganese steel telescopic boom provides a maximum above‑ground lifting height of 15 m and a maximum working radius of 13 m, making it easy to deliver loads from floors, rooftops, or around equipment foundations to target positions, reducing the need for frequent crane repositioning.
Crawler Undercarriage for Restricted Passages
The approx. 3‑ton lightweight self‑weight combined with rubber tracks enables movement through passages about 1 m wide. The rubber tracks help reduce direct wear on indoor floors and finished surfaces, making the crane suitable for workshops, station buildings, and other sites with strict floor‑protection requirements.
Operation, Safety Design & Optional Configurations
Standard Operating Configuration
It is available with engines from Changchai, Xinchai, Yanmar, etc., meeting Euro V and EPA emission standards. With a robust engine and a diesel/electric dual‑power system, it adapts to various on‑site power conditions. The user‑friendly control panel supports fine‑motion control for precise positioning.
Outrigger Support & Leveling
The three‑section extendable outriggers use manual extension and hydraulic automatic support, allowing adjustment of the support spread according to the available space around the crane, providing a stable base for lifting operations. Outrigger arrangement should consider ground bearing capacity.
Options & Customization
Wireless remote control, load‑moment indicator, and hydraulic jib are available as options, which can be selected based on project requirements for operating distance, load monitoring, and lifting coverage. Onchtech supports OEM, ODM, and OBM cooperation for configuration, appearance, and branding adaptation.
Typical Applications
The 4‑ton spider crane primarily handles lifting tasks where the equipment must enter restricted areas before hoisting. Typical working conditions include:
Floor & Rooftop Lifting
Using the telescopic boom to lift electromechanical equipment, materials, or components to designated installation positions on building floors, roof edges, or interior construction zones.
Substation Maintenance
In environments with limited passageways and equipment spacing, the compact crawler approaches maintenance points to assist in component replacement and equipment servicing.
Municipal Engineering
Suitable for lifting materials near road auxiliary facilities, underground entrances, and building gaps, with outriggers arranged according to available site space.
Factory Maintenance
During installation and maintenance of production equipment, pipelines, or moulds inside factories, the rubber tracks are more suitable for areas requiring floor protection.
