Bobcat reveals Bobdock

Nick Johnson reports on the latest machine developments unveiled by Bobcat recently during its Demo Days in the Czech Republic.

Fully automatic quick couplers that allow an operator to quickly interchange different hydraulically powered attachments directly from the machine cab are becoming increasingly common on 360° excavators and articulated wheel loaders. Not having to move out of the machine to couple-up or disconnect the hydraulic hoses saves time, eliminates oil spills and enhances site safety. And now these worthy bonuses are being applied by Bobcat to its skid steer and compact tracked loaders.

used on different Bobcats in a hire fleet. The battery powered system can be fitted on any Bobcat machine from the S100 to the T870 with SJC joystick controls.

A receiver unit complete with amber/green strobe lights and a horn is mounted on the roof of the machine and a control mode selector/emergency stop button box is placed on top of the tailgate. The machine can then be operated remotely using the two joysticks and switches on the weatherproof portable control box. Battery life between recharges is said to be 20 hours and the system has a password-protected keyless start.

Compact loader addition

When used with the Power Bob-Tach, the Bobdock allows hydraulically powered attachments to be connected without leaving the cab.

Now in the final stages of testing, the new Bobdock system will be able to directly pick up existing hydraulically operated Bobcat attachments if they are fitted with a special adaptor plate. New implements will be offered with a dedicated Bobdock connection plate.

During a recent series of Demo Days staged by Bobcat at its Training Centre in the Czech Republic, the system was demonstrated using a Bobdock-equipped S770 skid steer loader. The operator was able to rapidly switch between a grapple bucket (with hydraulically operated clamps) and an HB1180 hydraulic breaker without leaving his cab. The removal and connection of each attachment in turn was very quickly accomplished using the established Power Bob-Tach system, whilst the addition of the Bobdock adaptor plates eliminated the need to dismount to manually connect or detach the hydraulic hoses. These intermediate attachment adaptor plates require short connecting hoses which could, in some applications, be vulnerable to site damage.

Remote control system

There have been remote-controlled Bobcats in the past, but now the company is refining a new CE/ISO compliant system, which was demonstrated on a T650 compact tracked loader. This ‘plug and play’ system can be installed or removed in minutes, so it can be readily


The latest Bobcat compact loader is a new version of the top-of-the- range T870 with a new 5-link torsion suspension undercarriage. With an operating weight of 5,863kg and a rated operating capacity of 1,726kg, it replaces the previous T870 which had a roller suspension system. Distinguished by its more open design, the new undercarriage has an additional fifth link on the rear axle for stability. This acts like an independent suspension to increase ride comfort and to reduce the rocking effect typically associated with some other track torsion systems.

The new undercarriage also has a larger drive motor with continuous lubrication, wider dual-flange front idlers and rollers to minimise wear and provide a smoother ride, and a 20% larger circumference rear idler that is positioned further back to allow for increased downward force to the cutting edge of the bucket. Longer tracks increase flotation and reduce ground pressure.

The machine has auto-track tensioning so there is no need to manually adjust the loader’s track tension with a grease gun.

Bobcat has developed a new radio remote control system for its loaders with joystick controls.
