The Liebherr LR 1300 SX is a 300 metric tons (331 U.S. tons) lattice boom crawler crane with an innovative self-assembly and self-loading system that enables unloading and assembly without a setup crane. In this capacity category, cost-effective transportation and quick set-up time play is ideal for crane rental companies and contractors to get lifting. 

The main boom has a maximum reach of 92.04 m (302 ft). This versatile crane's configurations enable the crane to reach various heights. to meet the demand of the crane lifting project with boom and jib extensions reaching up to 169.16 m (555 ft). 

A high-power Liebherr D 856 A7 SCR engine with a 238-gallon fuel tank, pushing 270 HP/2, 000 rpm powers the crane. The main winch, luffing jib winch, and boom winch are compact and easy to assemble. The hydraulic system uses an axial displacement pump that supplies the open-loop hydraulic system for boom, jib luffing, and travel. The main hoist winches and swing are operated in a closed-loop system. All functions can be operated simultaneously.

The crawler’s propulsion uses an axial piston motor, a hydraulically released spring-loaded multi-disc brake, and hydraulic chain tensioning. The swing consists of roller bearings with external teeth. There are 2 swing modes, speed control or free swing. 

The crane operator cabin cab has an ergonomic design and is insulated against noise and vibration giving the operator comfort for those long working hours. The control system developed by Liebherr includes all operating and control functions of the crane and permits very delicate and secure lifting. The load capacities are automatically calculated during operation. The crane is equipped with proportional control for all main movements, which can be carried out simultaneously. The crane is operated with two multi-directional joysticks, the right for winch one and boom, the left controls winch two, and swing control.
